This single family luxury residence employs a unique 'double hull' design where each floor is an opposing arch. This combination of 2 simple shapes creates an off-set mass where interior space interlocks with extrerior space and overlapping volumes create shade overhangs and secluded private spaces. Even though it does not have conventional form the design provides ample square footage, a large yard area and big upstairs deck on a conventional 12,000 Sq, foot lot.
