Stone cladding and a glazed corner define Pretpec, a compact guest annexe created for a house on the Croatian coast by Zagreb architecture practice Argu Studio. Argu Studio chose to make the new annexe the same compact size, a decision founder Marko Gusić describes as a critique of "uncontrolled development" in the area. "In doing so, the house positions itself as a critique of uncontrolled coastal development and the loss of spatial measure." The blockwork structure of the annexe has been left exposed internally and clad externally with irregular stonework, unified by a whitewashed finish. "The architectural language is informed by the existing house and its broader context, particularly through material presence, surface texture, and modes of use," Gusić explained.
