Situated in Brazil’s Quinta da Baroneza is the stunning Casa HS designed by Studio Arthur Casa. A palatial residence offering 11,000 square feet of space, the architects managed to make the property feel even more spacious by building walls that swing out at a moment’s notice for an open-air living experience. The facade of the house features perforated metal planning which serves to add privacy from the outside while still offering its residents a light-filled space indoors. Split into two areas: one for children and guests and another consisting of common spaces and the master suite, the two halves are joined by an open square pond. Featuring extensive recreation areas including a pool, decks and balconies, this house offers its residents a truly seamless indoor-outdoor experience.
