Architecture, Building and Structure Design ARC Residence House by Caroline Andrusko This residence in Curitiba is a contemporary interpretation of Brazilian Natural architecture that blends clean volumetry, natural materials and calibrated light. The design responds creatively to a steep site, creating fluid indoor outdoor continuity and layered living levels. Movable muxarabis, exposed concrete slats and Nuvolato marble give identity, while integrated landscape and smart, solar based systems ensure comfort and sustainability.
