Extensions and roof extensions in Zaandam

Soft peat ground and timber foundations: here every conversation starts below the floor.

The Zaan region sits on peat, which makes it the area where we most often recommend a foundation survey before anything at all is drawn. An extension that is not founded correctly settles visibly here and pulls the joint with the existing house open. That is not a theoretical risk, it is why you see leaning facades in older Zaandam streets.

Good news for roof extensions: precisely because the subsoil is soft, weight is the deciding factor, and a light timber frame structure is exactly the right answer to that. Post-war districts such as Westerkoog and Rooswijk also have many houses with flat roofs, which is the simplest starting point there is.
