A modest rowhouse renovation in Arbúcies, Spain by Saizverdoux Arquitectos centers both physically and conceptually around a staircase that takes a different approach to forming the core of its habitat.
The concrete base rises right up from the floor, as if it were built into the foundation itself. This transitions to a metal-and-white tread-and-rail system, which in turn passes through the white-and-wood-frame ceilings along the way up.
New views and connections were created from this revamped spiral, and internal walkways span out from it at various levels as well, as seen in the sections above.
The result is a core means of circulation that seems at once to pull from its material surroundings and push then expand into them. A fascinating effect throughout.
