‘Building improvisations’ would like to give a positive impulse to the relation between client and architect. We look for new design and production methods for houses to make them more personal.We build a garden house from refuse and unusual materials in which the design process coincides with the building process. Through moulage technique of draping materials on improvised structures we work with trial and error, a process in which the client can also intervene. The 1:1 mock up becomes the actual building.
