In this single-storey contemporary urban home in São Paulo, Brazil, Focus’s iconic Gyrofocus central fireplace is right at home in the stylish, minimalist interior. Barely visible from the street or the neighbouring houses, Casa V4 brings the indoor and outdoor space together through its system of retractable glass doors that open onto an interior garden. The glass gives the impression that the house has open walls. Casa V4 was nominated for an award in the ‘House’ category at the 2012 World Architecture Festival. .
