The "Huisjeshuis" in Breda (2003-05) is a single family house developed as an affordable alternative for the rather boring and limited but relatively cheap catalogue houses. It exists out of a collection of standard shelters with an insulated hall system as a basis. In the specific case of Breda this concept results in a composition of a Romney hall as a basis with two wooden garden houses used as office space, a greenhouse in the garden being the additional 'outside' bathroom, and a siberian log house as sauna.Besides the invention of the polyester products also the heating system is developed especially for the half round shape of the hall. This shape makes the use of a wall radiation heating and/ or cooling ideal. Therefore in between the inside and outside cladding, in the curves of the inside plate 1,8 km of wall radiation pipe is braided in in 13 separate groups. By this you create a fast working system that doesn’t need to warm up a huge mass as with a standard floor heating system.
