Sustainable architecture: a straw house
© Kees Hageman,
Unlike the traditional hut which is evidently the architect’s source of inspiration, Arjen Reas' home combines a brick structure and foundations (something huts did not normally have) with a roof of straw which embraces the bricks and descends along most of the building’s height, clearly to insulate and shelter it: the straw’s fine structure provides constant protection against the elements, providing thermal and acoustic insulation to save energy.
If we are to find concrete applications of sustainability to everyday life, we must combine it with the styles, rhythms and demands of the private and public aspects of the home. This is what Reas was asked to do, and he managed to reconcile the insulation required of a home with a reduced environmental impact with the requirement of interaction with the landscape through dialogue between interior and exterior. This was made possible precisely by the combination of straw with “canonic” plastered brick, permitting inclusion of large windows that interrupt the compact straw surface to provide plenty of views of the home’s surroundings.
Built on two levels, the home is bathed in natural light, both in the public spaces joined together on the ground floor and the bedrooms and bathrooms upstairs and in the attic. The key space here is the master bedroom, which extends out to include the bathroom, from the bathtub in the centre of the room next to the double bed to the private and public areas containing the sinks and the shower room.
