House B Hasselt is a project designed by UAU collectiv, the surrounding landscape of the river Demer and the program gave rise to a strict and straight-lined basic volume in which patios are recessed and boundaries between inside and outside appear to become blurred. These patios are experienced as “positive” outdoor areas that spatially and visually show a strong link with the indoor areas. The architecture is designed by an interplay of surfaces and volumes that is created where walls, window surfaces and floating volumes touch at the corners. The surprising volumetry has its strength in the degree of execution on the level of detailing.
