The overall plan for 'Langerak' is characterized by its polder-based structure: north-south 'polder strips' with the elongated fields to be built on situated in between.
Our plan contains five of these fields.
- For two fields in the east, we built a single type of house (type A) in residential courtyards running east-west. At two points, these courtyards converge with the access road. Here the houses are accessed directly from the road, with parking on their own grounds. At three points the courtyard can be kept free of cars; parking is provided under houses specially designed for this purpose, or directly opposite the courtyard. For these three residential courts, which are accessed by bridges and border on the green polder strip, the idea was to implement complete paving under a green roof.
- For the north-west edge, patio houses with garage were developed (type B). They create peripherally, on the boundary of the plan area, a striking serrated wall. The living spaces of these houses enjoy a view over the impoldered land via the private patio.
- For the south-west edge, terraced housing was developed with the high façade facing the adjacent polder land (type C).
- For the north field, two types of houses were developed. On the striking corner position indicated in the overall plan, there is a six-storey block of flats (type E), which rises up directly out of the water.
- In line with the flats, there is a narrow 3-storey house (type D), which also rises up out of the water as a residential wall.
The entire plan provides for north-south lean-to roofs. When approaching from the west none of these roofs can be seen, but coming from the east you see a sea of roofs, which gives this plan its character.
