Utzon House

Utzon tells us he first built a full-size wooden version of the house in order to gain an impression of how a house with 130 square metres of living space would look in practice. Careful consideration was given to the surroundings: sun, view and shelter from the wind. The result was that he decided to have a completely closed wall along the northern side and an open glass wall for the southern facade. The builders agreed to work under Utzon's direction without plans. The north wall was first completed so as to establish the basic geometry. The kitchen and bathroom were then added and the remaining rooms were arranged with movable pinewood partitions and doors in order to facilitate any subsequent alterations. The materials used inside and outside are the same: yellow-white bricks, Oregon pine and aluminium. Yellow tiling is used both at the top of the walls — with hard-baked tiles — and in the kitchen, grill niche and shower as well as for the fireplace. The absence of windows in the children's rooms along the north wall has been mentioned as a possible disadvantage but they were lit by skylights.
