What Is the Most Accurate Building Cost Estimator?

Introduction

“I’m planning to build a home — but how do I even begin to estimate the cost?”

Whether you're a homeowner preparing for your dream build or a builder quoting projects regularly, estimating construction costs is one of the most important decisions you’ll make.

A good estimate gives you:

Budget clarity

Tender confidence

Control over financial risk

And peace of mind

In this guide, we’ll walk you through how to estimate building construction costs in Australia — the professional way — and show you how to avoid common pricing mistakes that lead to budget blowouts.

Step-by-Step: How to Estimate Construction Costs

1. Review Your Plans and Project Scope

It all starts with your architectural drawings and project brief.

You need to know:

The number of floors

Types of materials and finishes

Special features (basements, custom cabinetry, solar, etc.)

Site conditions (sloped block? access issues?)

Tip: The more detailed your plans, the more accurate your estimate.

2. Perform a Quantity Takeoff

A takeoff involves measuring the quantities of all materials and labour required. For example:

Cubic meters of concrete

Square meters of tiling

Lineal meters of cornice

Number of power points

Tools we use: PlanSwift, Cubit, Bluebeam Revu These tools make it fast, precise, and export-ready.

3. Apply Local Material & Labour Rates

This is where accuracy matters most. Use:

Local supplier prices (Bunnings, Reece, CSR)

Labour benchmarks for your city or region

Equipment hire and logistics (cranes, scaffolding, skips)

Example: Bricklaying costs in Melbourne are not the same as in regional WA.

4. Add Overheads, Contingency, and Builder’s Margin

Even the best projects come with surprises.

Include:

Supervision and admin costs

Permits and insurance

5–10% contingency

10–20% builder’s margin

Failing to include these = profit loss or client disputes later.

5. Deliver a Professional BOQ or Estimate Report

Wrap everything into a Bill of Quantities (BOQ) or a detailed cost breakdown.

Your final estimate should include:

Materials and labour

Subcontractor pricing

Trade-by-trade cost structure

Notes for variations

At AS Estimation & Consultants, our BOQs are:

Tender-ready

Bank/loan-ready

Format-compatible for builders, architects, and developers

Real Example

Project: Single-storey home in Brisbane Size: 200m² | Build Type: Brick veneer Estimation Process Output:

$2,300/m² × 200 = $460,000

5% contingency = $483,000

15% margin = $555,450

Online calculator showed $410,000 — missing site costs and labour uplift.

FAQs

1. Can I estimate my own building costs?

Yes — but only to a rough extent. A professional estimator provides accuracy, risk coverage, and compliance.

2. What is a takeoff?

It’s a detailed measurement of all required construction quantities — from concrete to tiles.

3. How accurate is a BOQ?

With professional software and real pricing, our BOQs are within 3–5% of actual build cost.

4. What if I don’t have full plans yet?

We can provide preliminary estimates based on concept drawings and assumptions — great for feasibility studies.

5. Can I use your estimate for my bank or tender?

Absolutely. Our estimates are used for loan approvals, builder quotes, and developer tenders.

Final Thoughts

Don’t guess your way through a six-figure construction project. Estimating is part science, part experience, and part negotiation — and it’s worth doing right the first time.

When you work with AS Estimation & Consultants, you’re working with professionals who:

Use licensed software

Know your local construction market

Deliver fast, formatted, reliable BOQs

Baby In A Basket

A short ficlet where Glinda finds a baby in a basket in their doorway and wonders if her lovers gave birth without her.

Glinda huffed as she got out of the taxi, briefly thanking the driver. She had gone to survey the construction of an office building in Emerald City with that insufferably detail-lacking stand-in for her client, who kept asking why there needed to be ramps in all the ground-floor facilities and why the spacings had to be quite exact so a wheelchair could fit in. She couldn’t figure out if it was from genuine ignorance or cruelty, but once they’d suggested to remove the braille on the signs, as he assured her, no blind person would ever work for this company. Oz knows how close she was to banging his head with her clipboard, or perhaps making him slip and fall down a floor or two, she could make it look like an accident, or better yet, set an example. She wouldn’t be above being known for a workplace incident that involved the hospital.

But she also wouldn’t want to be convicted, and that’d be horrendible for her company, but maybe they deserved it.

Nonetheless, she was home, and her Fiyero and Elphie were waiting for her, no doubt with dinner being prepared as she walked to the street of their two-story home. She was very proud of being the head of renovation when they moved in, and she was still leading the garden’s existence, white against her beautiful pink tulips. She’s become rather fond of plants, or flowers, more of. Boq and Nessarose ran a flower shop together, and they were to thank for the rare potted plant in her home office that had green flowers. How they grew, Glinda didn’t know; she was simply thankful for their existence.

She walked over the path from the fence of the front yard to the door, littered with broken ceramic pieces. Ah, she remembered the day they all came together and smashed those ceramic pieces. Avaric had been devastated the day before it, sobbing over the ceramic set he won at a fair that Milla had said he only had for an hour. She was briefly terrified by Nessa’s fervor in smashing the plates, which Boq assured her was normal.

She was in the middle of removing her heels when she spotted a basket in front of their door. She looked around, but couldn’t recall noticing anyone running off and dropping a gift at their doorstep. It was off-season as well, and it was a plain basket, not even with a ribbon. Nessa always sent hers with ribbons, and she’s the only one who sends these things. She leaned down to pull off one of the many covers of the basket, noting it was too large before executing the action.

A sleeping blonde baby greeted her, a contented smile on its face.

Slowly processing this information, she called to her lovers, leaning on the doorframe, heels in hand. “Elphie, Fifi, did either of you give birth while I was gone?” Humor has a way to deal with hardships, including the sudden stress of a child at her doorstep, and a coping mechanism she was sure her lovers would appreciate.

“No,” came Elphaba’s voice, looking up at her from the kitchen and now the living room couch, gray in color simply because it matched the carpets they had already received from Fiyero’s family.. “Did you, Yero?” She asked, looking over her shoulder. Galinda took a sniff and found that the night’s stew had already finished brewing, and her Elphie was waiting for her blondes to come to the dinner table. 

“Did I what?” Fiyero’s voice was fainter, probably from upstairs, reorganizing Oz knows what. She had asked him to fix one of the guest bedrooms, so he’d have a room to himself during the day, which he could decorate. She sometimes regrets letting him spend so much time around Crope, Tibett, and Avaric during their college years.

“Give birth,” Glinda yells, staring at the baby in the basket, whose blankets had an odd lion motif. She had to appreciate the parents’ commitment to the theme, even if they dropped their flesh and blood at her doorstep with not a note in sight.

“No,” thundering footsteps came her way, with her boyfriend in a tank top, fresh from a day’s work and a hundred percent ready for a bath, in her opinion. “Why?” He asked, rubbing his hands with wet wipes, covered in dust.

“Because there’s a baby in a basket on our doorstep.”

“A what?!” Her darlings cried in chorus.

The Role of Microfinance Institutions in Build Change’s Retrofitting Strategy

The year is moving fast; my time supporting the team in Colombia is over. My time is now fully committed to the program in the Philippines.

During my initial trip, I had the chance to visit some of the communities where Build Change has been working and become familiar with the existing tools used in these communities. Also, I was introduced to the crucial role that microfinance institutions (MFIs) play in Build Change’s strategy to retrofit vulnerable houses in the Philippines.

A lot of questions came to mind after that trip. Specifically, how to transfer the governmental responsibility of having safer houses for the low-income population to an external agent, and how to make MFIs’ business of providing loans to retrofit houses profitable? Compared with Colombia, where the government plays the principal role of providing grants to homeowners to retrofit their houses, there is very little government involvement in improving informal housing in the Philippines. Instead, microfinance institutions play a pivotal role in working directly with homeowners to finance housing retrofits.

MFIs have been working in the Philippines for many years. According to the Banko Sentral ng Pilipinas and the Asian Development Bank, MFIs are organizations that offer a broad range of financial services such as loans, payment services, money transfers, and insurance products to low-income homeowners or households and their microenterprises. Small loans from microfinance institutions are recognized as an effective method of directly improving the lives of those in need — a service that can often have a long-lasting impact.

Homeowners and households must successfully navigate several steps to obtain credit from an MFI. For example, the homeowner has to submit a membership application, there is a background check investigation, there is general documentation to be filled out, and the homeowner must pay a safety deposit that is usually 20% of the total loan (applicable on some loans). This last requirement reduces, in general, the total amount of money that can be used in retrofit applications.

Deficiencies in informal construction in the Philippines are similar to deficiencies identified worldwide in these types of structures, including a lack of a ring beam on the top of masonry walls, inferior quality materials, inadequate locations of openings, excessive openings in shear walls, irregular layouts, and high gable walls. Developing a full retrofitting assessment and solutions for a house requires a lot of engineering effort and time in order to obtain buildable documents and building permits. As a result, Build Change developed a simplified approach focusing on eight deficiencies:

All exterior walls must include a minimum solid wall length of 1.5 meters or 35% of the total length of the wall. This requirement reduces potential torsion effects in the house.

Columns are required at the intersections and ends of walls, allowing the transformation of a partially confined or unconfined masonry system into a confined masonry system.

Ring beams are required on top of the walls. Many homeowners of informal one-story houses wait to build a ring beam until the concrete slab is poured during a second floor expansion. In the meantime, these houses are vulnerable to earthquakes and wind forces.

Openings must be protected by the placement of confining elements around them. This enhances the performance of the wall as a confined masonry member.

For unplastered masonry walls, 1.5 centimeters of mortar plaster are specified at each side.

If parallel walls spaced more than 3 meters apart exist, a new perpendicular CMU wall 1 meter long between parallel walls is required to buttress the walls for out-of-plane lateral forces.

If a masonry gable wall exists, two options are specified: Construct a slanted ring beam at the top of the gable wall; or demolish the wall and replace it with a gable wall made of a lightweight material such as timber.

Anchor the roof framing to the ring beams with metal straps, if not previously completed.

The full application of this retrofit strategy typically creates a total scope of work that far exceeds the loan amount accessible to homeowners through an MFI. Therefore, prioritizing and dividing the scope of work into different phases is required. It demands extra engineering time. To make this work scalable, existing resources must be improved to automate as much of this process as possible.

MFIs use loan officers as liaisons between the institution, the homeowner, and Build Change. Loan officers are usually salespersons without a technical background. However, the assessments that they perform require the loan officers to take actual house measurements. With very little guidance on how to take accurate measurements, they may find this process too complicated. Any confusion when performing an assessment will likely affect the quality of the final bill of quantities (BOQ) and scope of work.

Figure 1. Tool developed for loan officers to guide them through assessments.

In response to these problems, Build Change has created an XLMForm application using FieldSight, an application developed by UNOPS and the World Vision Nepal Innovation Lab to ensure Nepal is properly rebuilt after the devastating earthquake of 2015. This platform allows data collected by loan officers in the field to be directly monitored from Build Change’s office. A new feature of the app involves using pictures to help loan officers identify the elements that must be measured and minimize the judgment and interpretation required by the loan officer.

Currently, only a single typology (one-story houses without future expansions) is available in this simplified procedure. However, the goal is to extend the app to cover other typologies, such as one-story houses with the capacity for future expansion, two-story houses with a lightweight roof, one-story timber houses, and two-story houses built from multiple materials.  With the development of more modules that can cater to more typologies of homes, we can cover a more significant portion of the market.

Figure 2. Visiting a house in the Philippines with a loan officer of Kasanagaka (local MFI).

I had the chance to visit an MFI client in Southville, Rodriguez, Rizal. The requirements and scope of work determined previously for this client’s house by the MFI loan officer were very different from the type of intervention the homeowner was expecting. Many factors could have contributed to these differences. However, in my opinion, loan officers require more training and improved, user-friendly tools to ensure that a scope of work is generated that is consistent with the homeowner’s desires.

To conclude this blog, I believe that the approach and strategy adopted by Build Change to promote safer housing and better construction practices is correct, given the lack of government involvement in informal housing vulnerability. Homeowners committed to having a safer house play a key role in promoting better construction practices among local builders.

Improving construction practices is a long road, but it is the only way to ensure safer housing on a large scale, years and decades into the future. This aligns with Build Change’s mission to save lives and significantly reduce injuries and economic losses in earthquakes and windstorms. Additionally, becoming involved with the retrofitting of vulnerable houses can be a source of growth for MFIs, allowing them to reach more homeowners. That said, Build Change must continue to help MFIs with the technical support, the development of the tools, and the training of loan offices to achieve our final goal.

A Handy Construction Glossary: 38 Common Terms Defined

Make no mistake about it, the construction industry is complicated, with thousands of terms and jargon that are tough to grasp for anyone new to the industry.

If you’re just getting involved in construction management, or are trying your hand at your own home project, it’s helpful to understand some of the basic terms used by the industry.

We’ve put together this handy construction glossary that identifies some of the most common terms you’re likely to encounter as you get to work on your construction project.

1. Aggregate: A particulate material which is made up of sand or crushed stone. Aggregates are used in materials such as concrete and are a fundamental part of building foundations.

2. Backfilling: The process of refilling trenches or holes created during excavation, especially around foundations.

3. Beam: Beams run horizontally along the main walls of a building at ceiling level, supporting the structure.

4. BIM: BIM (building information modeling) is the process of creating a computer model of a building that includes all of the details of that structure, from its basic layout to the smallest measurements.

5. BOQ: The bill of quantities is a contract document that contains a list of materials and workmanship involved in a construction project. It is necessary for properly pricing a project.

6. CAD: CAD (computer-aided design) refers to using architecture software to create detailed models of buildings to speed up the design process, allow for more creativity, and ensure greater accuracy in measurements.

7. Caulking: A flexible, rubbery type of material that is used to seal gaps in a joint.

8. Ceiling joist: Parallel framing members that support ceiling loads and are themselves supported by load-bearing walls.

9. Circuit breaker: A switch in the electrical panel that shuts off power to certain parts of the building.

10. Concrete: A building material created by a hardened mixture of cement, gravel, sand, and water. It is used for slabs, columns, and other types of structures.

11. Construction management software: This software is designed for construction managers to help them more efficiently run a construction project; it can include features to manage accounting and financials, documentation, and team workloads.

12. Dimension: A dimension is used in the planning stage and refers to a measure between two points.

13. Drywall: A panel made from gypsum plaster that is wrapped in cardboard. It is commonly used as a fundamental material for framing a building.

14. Ducts: Piping that carries air throughout a structure.

15. Egress: A way of exiting a structure, such as a window or door. Laws require a certain number of egress windows in certain parts of a home.

16. Field measure: Taking measurements within the structure itself rather than relying on blueprints.

17. Floor plan: The floor plan refers to the layout of the building. It is a drawing of the horizontal section that shows how the different spaces relate to each other.

18. Girder: The main horizontal support of a structure that supports smaller beams.

19. HVAC: An abbreviation that stands for heat, ventilation, and air conditioning.

20. I-beam: A beam that has a cross-section that looks like the capital letter I. Girders often have an I-beam cross-section.

21. Insulation: Material that’s designed to prevent heat from leaving or entering a building. Insulation material is placed within the walls, ceiling, or floor of a structure.

22. Joist: The location where the surfaces of two components are joined.

23. King stud: A framing member that runs from the bottom to the top of a panel or sheet.

24. Lath: A metal wire on the frame of a building that serves as a base for laying down stucco or plaster.

25. Load-bearing wall (partition): A partition or load-bearing wall carries the load of the structure above it. As a result, they cannot be removed without compromising the integrity of the structure.

26. Mortar: In masonry, mortar is the paste that is used to bind stones, bricks, and other similar types of units used to construct the walls of a building. Mortar can be made up of a variety of things, such as asphalt, pitch, or clay.

27. Particle board: A substitute for plywood that is composed of sawdust mixed with resin.

28. Plywood: A panel of wood that is made from multiple layers of veneer, compressed together.

8 Ways to Avoid Going Over Remodeling Budget

Kitchen remodeling is a beast of a project that needs to be carefully planned out from the beginning to the end, in order to get successful results. However, no matter how much restraint you show in your design, sometimes you’ll definitely hit some little bumps and hiccups that will make you spend a little more than your remodeling budget allows. All you can do is tighten the seatbelts and prepare for a seamless ride by having your consultant prepare itemized BOQ’s (Bill of Quantities) that lists out the nitty-gritty of your expenditure budget and go from there.

Even then, you can never tell during the live project. Keeping your toes well and within the budget is pretty hard, especially when you’re vying for the prettiest and shiniest things in the market. In the beginning, you will have no idea what your dream vision will cost, but with the passage of time, you will intimately get to know the market prices and begin to apply them within the context of your space. There are many reasons that a kitchen renovation can go over budget – some of them accidental, and many of them not. Today we will be looking at 8 ways to avoid going over budget with your kitchen design.

1. Playing out of your league

One of the mainstream and most universal reasons that kitchen renovations go beyond the restricted budget is when the clients begin to select more upscale products, material and finishes for their space. It’s human nature to want better for yourself, but when you’ve got a set, allocated budget, this can definitely hamper the success result and ultimately, the timeline of your remodel.

So when you go out shopping for those finishes and accessories, take a quick look at your estimated budget – how much you’re willing to splurge on what, and will that be worth it in the grand scheme of things – before you actually go out and bust it. If you keep finding reasons to splurge on things then the costs would definitely rack up quickly, and will ultimately effect the set-out timeline of your renovation.

2. Customized cabinet designs Professionals have estimated that about 60% of the allocated budget of any kitchen remodel goes into the cabinet designs. The actual costs of a cabinets depends on whether they are customized, bought prefab from the market or are even semi-customized. The varying range between these three categories could differ from $50 to $2000 depending on whether or not you choose the utmost customization.

The key to controlling your budget in this aspect is by doing a thorough research on the market price of every category before you start the renovation, and decide if you still want a certain upgrade if you cannot fix it in your allocated budget.

3. Additional features

External finishes aside, another major cause of over-budgeting is splurging on special features like in-built cabinet customization. Attractive little accoutrements like magic corners, pull-out shelving and organized drawers may look like fanciful things but these cost a fortune and can waylay your budget by thousands of dollars.

The nifty little add-on’s are infinite in number. You could keep adding newer, shinier things to your cabinets and create a heft dent – up to at least $15,000 – in your budget without a sweat. So carefully consider these small attractions and definitely keep a reign on it.

4. Knowing your appliances

The cost of appliances depends completely on the make, model and brand name you’re going for. Of course luxury appliances cost way more than the regular ones and the range in between can leave a gaping hole in your allocated budget.

The point is, that of some of the brand name appliances like Viking could cost a whopping $15,000 per product, and the consultant has estimated the entire budget of your project to be around $35,000 then is it really worth it to blow a chunk of your already established remodel allowance on something you don’t even need? You decide.

5. Countertops

Perhaps the most innocuous face makers of the kitchen design, the prices for these range vastly, depending on the materials. For example, plastic laminate countertops cost relatively less than granite or quartz when it comes to price per square footage. There are quite a lot of composite options in the market these days, so conduct a thorough research before you decide to blow your budget on something redundant.

6. Unknown structural blasts

You can never foresee a problem that you hadn’t considered even existed. These are the most dangerous of them all, and they can definite cost you a pretty penny. An example of such a phenomenon is when you open up the drywall and it is riddled with termites, or if you find an undetected water leak or even if you unknowingly tear down a load bearing structural wall and have to recover the support by paying for a beam that was not previously in the written budget. These may be unforeseen, but they could certainly upset your budget.

All we could suggest is that you do a pre-project reconnaissance of your building before launching a full-scale construction effort in order to minimize the damages.

7. Researching the codes

Building codes, if not followed properly, could get you in so much trouble with the authorities. These dictate the kind of exhaust and hood fans you should be using in your kitchen, along with the extension bylaws of the area. If you do not comply with these codes, a surprise inspection might get you slapped with a heavy fine.

8. Easy whimsy

This is maybe the most dangerous budget buster of them all – being half-way into the guts and core of a remodel and deciding that you do not want that particular design installation, or that finish just doesn’t fit in with the rest of the aesthetic. It will screech your entire project to a halt, which will result in inordinate payment for the labor, extra charges for the redone design work and finishes. So decide on what you want before everything is way ahead of schedule to be taken apart again.

Conclusion

Now that you know just what kind of obstacles might stand in in you and your dream budgets way, be very wary of making any unnecessary deviations.

…will increase the total cost due to engineering and labour needs.

3. Site Conditions

Flat blocks are ideal. Sloping or rocky sites need:

Retaining walls

Excavation

Drainage solutions

Access management (machinery, deliveries)

4. Finishes and Inclusions

Your finishes have a big influence. Options that raise costs include:

Stone benchtops

Hardwood flooring

Frameless shower screens

Smart lighting and automation

Budget homes might come in at $2,000/m², while higher-spec 3-bed homes can exceed $3,500/m².

5. Location and Labour Rates

Metro areas typically have higher labour costs. Remote or regional builds may face material delivery surcharges.

Sample Estimate Breakdown (Brisbane Example)

Home Size: 180 m² Build Type: Brick veneer, single-storey Finish Level: Mid-range

Base Build: 180 m² × $2,400/m² = $432,000

Site Works & Permits: $18,000

Contingency (5%): $21,600

Estimated Total: $471,600

Add landscaping, driveways, fencing, and approvals to get your all-in cost.

Tips to Stay Within Budget

Choose efficient floorplans with minimal hallways

Limit structural changes during the build

Stick with mid-range, durable finishes

Compare inclusions lists between builders

Request a detailed cost breakdown (not just a lump sum)

FAQs

1. Can I build a 3-bedroom home for under $400K in 2025?

Yes, in regional areas or with basic inclusions on a flat site. In major cities or custom builds, expect to spend $450K–$600K+.

2. Is it cheaper to build or buy a 3-bedroom house?

Buying may seem cheaper upfront, but building gives you full control over layout, energy efficiency, and location. Long-term, it may offer better value.

3. What’s the cheapest way to build a 3-bedroom home?

Go for a standard single-storey design with simple rooflines and finishes. Use lightweight cladding, avoid custom cabinetry, and choose builder-included packages.

4. Do house and land packages save money?

They can, especially with volume builders, but be sure to check what’s included — some don’t cover fencing, landscaping, or driveways.

5. Do I need a professional estimator or is a builder quote enough?

Builder quotes are helpful but often vary in scope. A detailed cost estimate or BOQ gives you transparency and negotiating power.

Final Thoughts

The cost to build a 3-bedroom house in Australia is shaped by dozens of moving parts — from block size and slope to kitchen benchtop finishes.

Square metre rates can give you a rough starting point, but only a tailored estimate based on your plans will reveal your true build cost.

Before you sign a contract or commit to a builder, take the time to:

Understand your site

Compare quotes

Review inclusions

And get a professional estimate if needed

It’s the smartest move you’ll make in the building journey.

Can I Use a Building Cost Calculator for Renovations?

Introduction

You’re ready to transform your kitchen, add a second storey, or finally build that backyard studio — but first, the big question:

“Can I use a building cost calculator to estimate my renovation costs?”

It’s a fair starting point. With countless free calculators online, it seems like a quick way to budget.

But here’s the truth: renovations are not like new builds, and square metre calculators don’t always work the way you think.

In this article, we’ll explore:

When cost calculators are helpful

Why renovations are harder to estimate

What factors most calculators miss

And how to get a detailed, accurate renovation estimate

How Building Cost Calculators Work (and Where They Fit In)

Most online calculators ask you to input:

Area (in m²)

Type of build (single or double-storey)

Finish level (standard, premium, custom)

Location

They then apply an average rate (e.g., $2,200/m²) and produce a ballpark total.

This method is simple and effective for:

Project homes

Flat sites

Volume builds

But for renovations? Not so much.

Why Renovation Costs Are Harder to Estimate Per m²

Renovations don’t follow the same rules as new construction. Here’s why:

1. Demolition and Waste Removal

Before you build, you have to remove. Calculators rarely include:

Demolition

Temporary supports

Asbestos removal

Rubbish disposal

2. Structural Uncertainty

You won’t always know what’s behind that wall — and surprises = extra cost:

Electrical rewiring

Plumbing redirection

Damaged joists or slab irregularities

3. Access and Site Limitations

It’s harder and more expensive to work in:

Tight spaces

Occupied homes

Multi-storey inner-city sites

Scaffold hire, crane access, and labour loading must be factored in — calculators don’t cover these.

4. Integration with Existing Structure

It costs more to “tie into” your current layout than to start from scratch. Example:

Matching flooring or brickwork

Adjusting rooflines

Bringing older sections up to code

When a Cost Calculator Might Help

A renovation calculator can give you:

A ballpark figure to assess feasibility

Cost comparison between standard vs high-end finishes

An idea of cost per room (e.g., bathroom vs full-house reno)

Use it early — but don’t rely on it for final planning or financing.

The Better Way: Professional Renovation Estimating

Here’s what we do at AS Estimation & Consultants:

Review your floor plans and renovation brief

Conduct a digital takeoff (materials, labour, waste, etc.)

Factor in site access and demolition requirements

Use local supplier rates and labour costs

Deliver a BOQ or detailed estimate tailored to your project

This results in a more accurate, realistic forecast — especially for:

Kitchen and bathroom upgrades

Storey additions

Structural extensions

Multi-phase renos or heritage properties

FAQs

1. Can I use a building cost calculator for a kitchen renovation?

Only for very rough pricing. A kitchen’s cost depends on cabinetry, electricals, appliances, and plumbing — which calculators can’t fully capture.

2. Are renovation estimates per square metre accurate?

Not usually. Renovation work is more labour-intensive and includes demolition and integration — driving up the cost per m² significantly.

3. What’s the average cost of a home renovation in Australia?

It varies widely. Basic bathroom reno: $15,000–$30,000. Full extension: $2,500–$4,000/m² depending on complexity.

4. How long does a professional renovation estimate take?

Typically 3–5 business days after receiving floor plans and scope of works.

5. Can I use your estimate to compare builder quotes?

Yes — our BOQs help you verify if builder quotes are missing scope or inflated in certain trades.

Final Thoughts

Building cost calculators are great for new builds — but they fall short when it comes to renovations.

If your project involves demolition, custom adjustments, or working around existing structures, your costs will be highly variable. That’s why you need a professional, renovation-specific estimate.
