At home in flood: danger as quality

Code PAB090


The project is located in un-exploited regularly flooded areas. It uses the dynamics of the water to create a deformation of landscape with a gradation from temporary to permanent. Combined with a gradual development of infrastructure according to the deformation, different programmes through the year and in time are generated.

The project is designed to be located in river deltas and regularly flooded areas and is assessing the impact of flooded (unexploited) areas where the water level changes through the year.
The observation of the on water living qualities in the Netherlands (houseboats and floating houses) offered the instrumentality for the design of a safe settlement inbetween a changing landscape according to water level.

"I want to wake up with the ducks, to see the coast changing through my window everyday …":
The observation revealed also the desire of numbered city inhabitants that want to live with the ambiguous conditions of this kind of nature but not in an actual houseboat and its related problems (renovation, lack of space, etc).

Project:

The concept is to use the dynamics of the water instead of fighting against, to create a. landscape generated public programme through the year b. safe housing in land that can be exploited.

The project consists of 3 stages:

1. The landscape manipulation is based on the delay of the thick layer of clay and the reveal of gravel in selected parts of a whole recreational site. This creates areas of different conditions and different height: low areas of gravel (flooded and deformed), 'in-between' areas of a thin layer of clay (sometimes flooded and open to deformation) and safe 'permanent' areas of a thick layer of clay (non-flooded, never deformed).
Achievement: a. a softer flow of water inside the land, b. the changing landscape provides the safety of de-intensification of forces of the water.

2. Introduction of soft infrastructure (pylons for gas and electricity and moving piers according to the water surface) for a. more water related activities when flooded, b. accommodation of temporary public activities in the summer (open cinema, birdwatchers, concerts, summer events, etc.)

3. Introduction of low rise housing development.
A continuous row of housing structure is applied perpendicular to the hightlines of the manipulated landscape. The whole settlement comes as a tissue to be applied on every landscape.

The house itself is never flooded while the percentage of dry public space is changing through the year.
The housing design is borrowing the house boat concept and translating the houseboat typologies:
Semi-private yard of 10x13 meters, togetherness and the idea of community, common row access, houses teamed in two (the possibility of a second boat).

The rows of housing are oriented in order to maximize solar access of the southern elevation and for better use of the unbuilt area.
The construction is based on common (reinforced concrete frame) and local materials.
The enclosed spaces are aligned with the contour of the plot, while the features related to the sun (windows & overhangs) adhere to the orientation. Most of the openings are on the water side, while the back side is a blind party wall with the main entrance and the insertion of the car.

Sustainability aspects:
Two devices are used to reinforce the community with a common sustainable system:
a. wastewater enclosed garden. A south sera works as solar collector and the enclosed garden purifies the greywater (washing, kitchen) and blackwater (sink food gringer, toilet, urine sources). Wasteliquids are transpirated and evaporated by the plants and a particle filter in each enclosed garden.
b. double roof of heat yielding material for canalization of the air evaporated by the plants.

Urban aspects:
Variation on the form of the continuous structure give the possibility for accommodating various programmes beyond housing.
