one column house by DiA architecture studio

‘one column house’ by DiA architecture studiointerior view

amsterdam-based DiA architecture studio has decided to incorporate a detached volume as an extension to the existing house which grounds closer to the lake shore and oriented towards the best landscape vistas, creating an internal patio between the existing house and the extension volume. the new addition establishes a clear division between the public and private areas – old and the new.

while the existing house will host two large bedrooms, the main bathroom in the ground floor and a secondary bedroom in the first level, all public areas will be linearly organized within the extension volume: open kitchen, dining place and the lounge area; all these spaces will share a wide open wooden terrace deck facing and open to the lake shore.

the new section will mainly be constructed by a reinforced concrete structure: a planar roof runs widely from one neighbor boundary line to the other and is strengthened by four inverted beams that converge in the only load bearing vertical element of the house. the column is formed by a pair of twisted concrete shear walls performing in different ways.
