Breklenkamp, the Netherlands
This ‘bakspieker’ (cottage used for baking bread) was built in 1738. However, in 1900 the tenant of the house wanted to expand it to include a pigpen. Baroness van Twickel, the owner of the land, didn’t like that as the oak next to the house would have to be felled. The tenant, who was apparently quite solution-oriented, found it no problem at all and built the extension around the tree. Every year, the size of the tree increases by about three centimeters, and the roofpanes move along with it.
