The 'villa s2' is a single family home located on ijburg island just east of amsterdam's historic city center. designed by dutch practice MARC architects,the house is located next to the water's edge which informed certain setback conditions, and needed to accommodate a guest area in the subterranean level. as a result, the house contains several split floors so that the ground level is actually about two feet above grade, bringing in natural light to the functions below the ground. the nature of the compact dwelling is expressed through a reflective folding structure clad in composite white stone tiles that sandwiches the program between, with high airy ceilings. all the interior spaces have a direct visual connection to the exterior landscape through frame-less three-layered glass partitions with carefully designed connections to maintain a clean aesthetic. the swiss sky frame window system allows the connection of moveable sections with a subtle substructure that disappears completely into the hosting walls. the wooden screens and components of the project are made of biopolymers from sugar cane and locally sourced FSC timber that would age uniformly. heat recovery ducts are hidden within the 38 centimeter thick floor planes, and four solar panels on the roof power the array of LED lights inside.
