A row of raw concrete gables give a zig-zagging profile to this summer house by Swedish studio Tham & Videgård Arkitekter on an island in the Stockholm archipelago.
In Situ Cast concrete volumes hearken to a boathouse typology characterized by a span of transverse gabled roofs. The pleated effect creates a sequence of varied room heights and open the possibility for a completely open living area. Despite a relatively shallow room depth, the site’s waterfront views are invited into the white-and-ash interiors with a continuous band of glazing.
Sea and sky additionally enter the space with walls of sliding doors along smaller, north-facing rooms, and operable skylights from smaller pitched ceiling spaces. This is an architecture informed by the material palette of its context, with a weight and color that connects the form to the archipelagic granite bedrock that embraces it.
