Archipelago House is situated on a plot in Stockholm’s inner archipelago, featuring granite cliffs sloping down towards a southern view, pine trees and low vegetation in poor soil. The project is an extension to a relatively newly built house, a long box facing the view, with a black-charred wooden facade and a gently sloping shed roof. The project is built of of four parts: an extension of the existing house, a pool house, a guest house, and a carport.

The extension is based on a wooden and steel structure, clad in vertical zinc cladding, with large sliding panels that open towards the southern view. The plan is based on a simple division into three equal-sized rectangles: a living room, a bedroom with a walk-in closet, and a large bathroom. To access the extension, a new, top-lit stairwell clad in light brick is added.

To the west of the main house, a freestanding pool house is planned, with large sliding panels facing the view and a new stone terrace that connects the buildings. The exterior of the pool house is clad in the same brick as the stairwell, while the interior is finished with limestone. Large round skylights illuminate the rear areas. To the east of the main house, stands a smaller guest house, clad in black-charred wood paneling similar to that of the original house. The carport is an open structure of wooden columns and laminated timber beams held together by steel cables. The project also includes a significant redesign of the plot’s landscape.
