Before considering building on this site, one must first consider our rights to alter what exists now, despite the spit’s man-made identity. The spit may be depiction of our sins, however this is no longer an abiotic dumping ground and the earth has reclaimed its material and created a living sponge. If one is forced to interfere and design a human structure, one must find a way to live cohesively with the ecosystems that exist. My proposal suggests our role is not to design the ecosystem but merely our relationship to it by closely regulating the extent our effect. We must make the sacrifices to existing nature minimal and worthy, and maximize cohesion and sustainability by joining natural cycles and behaving as a member not master of the site. The building can be seen as the body of an animal, a vessel to carry, to shape behaviour, to limit and to inform. The building is a set of organs within an organism, within an ecosystem and as a product of the landscape. The flow of energy and its transformation through the membrane and presence within the body shape the body itself, flexing and pulling it as the energy is traded through the flexible matrix between programs and is eventually output back into the natural world. The building must behave as a membrane, at the intersection of all natural conditions, transforming the potential energy of the site into comfort and functionality. The result is a building centered around a massive interior cob wall, performing as a system of ventilation, heating, cooling, bracing and occupation. These principles have distilled the building back to the original purpose: a machine that transforms conditions into habitat, which creates true belonging on its site and justification for its existence.
