A family acquires a tabià and the neighbouring hayloft portion, which is on the verge of collapsing. This portion gets demolished, while its stone basement is consolidated – allowing to reinstate the initial volume in the future. The structurally sound portion remains abandoned. Twenty years later there is an opportunity for re-building the missing portion, for creating an annex. The disused tabià is asymmetric in shape. The previously consolidated basement ensures structural independence to the new timber volume: a few centimetres’ gap separate it from the ancient portion. The addition retraces the missing part, thus completing the building complex. The intervention is declared through variations in the openings’ layout and in the cladding: the windows shift, the external joinery is set in, the back façade is clad in metal sheets. All of the design choices sit within the boundaries set by the building regulations.
