Architecture, Building and Structure Design House LW27 Private Residence by Stephan Maria Lang House LW27 is a private residence built on a relatively small site in a residential area. The white volume contrasts with rough natural stone elements. White plastered walls, oak floors and natural stone for floors, bathrooms, chimneys and walls shape the interior. On the ground level an open plan flows freely from east to west along the pool. Floor to ceiling sliding windows link inside and outside all year. The upper floor holds bedrooms with ensuite bathrooms. A planted roof terrace returns the sealed ground area to nature.
