Widlund House by Claesson Koivisto Rune
Swedish architects Claesson Koivisto Rune have completed a house on the coast of a Baltic island with slanted roofs and walls that make the building narrower in the middle.

This 'waist' separates the two storeys of bedrooms at the back from a double-height communal space overlooking the water at the front.

Villa Widlund on the island of Öland was prefabricated from white concrete and grey lines of sealant draw graphic lines across the facade.

Here's some more information from the architects:
Villa Widlund vacation house
Öland, Sweden
This house is like a funnel of light, space and sea views. The location is the west coast of the Baltic island of Öland.

The white concrete box is "corsetted" in the middle, creating slightly sheared wall and roof angles.

This gives the house both its direction and character, while also marking the difference between the rear private two-storey bedroom part and the communal double ceiling-height front part.

Precast concrete is perhaps not the most common choice for a private house at this scale, but was ideal for achieving the ultimate precision in manufacturing tolerance and colour/finish.

The concrete is not painted or surface-pigmented but solid white, which gives it a wonderful glow.

The joints between the concrete elements are carefully designed and positioned so that – instead of interfering with – they become part of the building's geometry and expression.

The sealant in between is gray to enhance the graphic effect rather than matching the concrete surface.
