Casa Peninsula, a weekend home in a coastal city close to São Paulo, is composed of three stacked abstract volumes which have been delicately positioned on a steep slope overlooking the Atlantic Ocean for minimum topographic impact. The house is divided in three parts: the rectangular base and the triangular superior volume, which have more private areas; and the transparent space in-between them where the common areas are located. The suspended triangular volume creates shaded balconies protected from direct sunlight, while the more enclosed and monolithic base provides more intimate spaces.
