This unusual roof addition sits atop a private villa in Stocksund, Stockholm, Sweden. The structure is formed by three equal-sized square rooms, that substitute the previous existing pitched roof. Each room contains big window panes and skylights opening the spaces to the nature outside.

The separate volumes house a living room, a walk in closet with a bathroom and a bedroom. the application of a dark copper material to the addition is visually contrasting to the rest of the exterior – firmly anchoring the renovation onto the old building’s rooftop.
