Mix House is a 1,200 sq ft spec house in Mattituck, on the North Fork on Long Island, designed for a local developer. The prototype design for a sustainable single-family house comprises of two bedrooms and is a variation of the courtyard typology. The bedroom bar, which spans the courtyard, provides shelter for the carport below while framing the end views to the harbor beyond. A suspended concrete fireplace and wood storage component divides an otherwise open living space. An outdoor deck with a swimming pool attach to the kitchen block and form a 3-dimensional knuckle at the intersection of the living spaces.
