Villa Deer is a combination of an old summer house and it’s modern extension. Existing 1960’s cabin was built to lakeside in a former municipilaty of Kisko in Southwest Finland. The old cabin was relatively small consisting only of one room and a sauna and bathing spaces. Idea for the extension was to make a modern and radical architecture compared to the modest gable roofed summer house architecture of the 1960’s. Slanted end wall and zig-zag facade facing the lake create contrast to the more common rectangular building mass of the old part. New and old was connected by using similar facade material and matching roof angles. Extension part was designed to continue from the living room as seamless series of spaces that’s seperatable if needed.
