Siza designed two housing blocks with 106 dwellings in the ‘social housing’ sector. The one building has 5 corners and the other 3. The houses in the 4-layer high building have a so called ‘portiekontsluiting’, which means, the entrance is facilitated with a stair, accessible from the street. The red bricks have a rhythmic pattern of large square windows. On the corners, several white smooth surfaces are made. In 1989-1993 a second phase was realized, with 238 houses on the Doedijnstraat and surroundings.
