Haiti | 1000 Passive Houses | V. Callebaut

[XXXXX]

Called “The Pearl of West Indies”, Haiti was during a long time the most visited country of the Greater Antilles representing the occidental third of Hispaniola Island. Devastated in 2010 by an earthquake measuring 7.0 on the Richter scale, the country has now to be rebuilt from new innovative architectural and town-planning concepts.

The Coral Reef project designed by Vincent Callebaut Architects plans a matrix to build a three dimensional and energy self-sufficient village from one and only standardised and prefabricated module in order to rehouse the refugees from such humanitarian catastrophes. This basic module is simply made of two passive houses (with metallic structure and tropical wood facades) interlocked in duplex around a transversal horizontal circulation linking every unit.

Inspired from a Coral reef with fluid and organic shapes, the overall project presents itself as a great living structure made of two waves dedicated to accommodate more than one thousand Haitian families. These two inhabited waves undulate along the water on an artificial pier built on seismic piles in the Caribbean Sea. From concave curves to convex curves, the housing modules are aligned and piled up by successive stratums such as a great origami. Between the two inhabited waves is created a sumptuous interior canyon in pixels with terraces and cascades of food gardens.

Actually, the laying-out in staggered rows of the plane-parallel base modules enables to superimpose the passive houses in cantilever and to multiply the vision axes towards an endless number of perspectives. Each roof of each module becomes then an organic suspended garden enabling to each Creole family to cultivate its own food and to use themselves their own wastage as compost.

This canyon is a true tropical ecosystem for the local fauna and the flora. Ode to the urban biodiversity, it is also the central axis of the communitarian life of this futuristic village and respectful of its environment. Between the waves of these ecological housing, the sinuous lines of the anti-seismic basement (absorbing the vibrations in case of earthquake) integrate the public functions of the social life. Aquicultural farms welcome pisciculture pools whereas the purification plant lagoons recycle the used waters before rejecting them in the sea.

The Master Plan can evolve and extends itself according to the «plug-in» principle. The urban framework of this ecological village remains thus undetermined, flexible and develops itself continuously according to the time and the space. New extension modules, also prefabricated in factory and brought by cargo will be actually added such as a giant meccano set to correspond to the needs of inhabitants completing the basic matrix.
