Competition Details


by Rui Filipe Maia dos Reis


The present proposal intends to provide a sense of safety and relative stability within a scenario of calamity. To make this possible, the draft focuses on two decisive aspects:

a) shelter
b) orientation

The sense of safety is supposed to emerge from the sheltering archaic symbolism of a cave motif.
Orientation is provided by using wide and transparent windows, which enable the people to keep their disturbed environment in view.


Both the dwelling unit and the sanitary unit are based on identical oval cross-sections, only differing in scale and alignment.

a) Four prefabricated curved modules, shaped from bended plywood sheeting fixed on an aluminium/plywood–substructure using bolted connexions, form a stable oval spatial unit.
b) This oval unit lies on two horizontal aluminium beams in order to be lined up horizontally and to finally form a dwelling unit. In the case of the sanitary unit, there is only one oval profile of four modules which has to be fixed onto a water-/wastewater tank.
c) The outer skin consists of an ETFE membrane with a high permeability to light. The edges of this plastic sheeting are reinforced with a clamping strip and tensioned perpendicularly to the cross-section plane towards the outside margins of the dwelling/sanitary unit. Below the membrane there is a ventilation space. In hot climates fresh air is sucked in from below the units, then it flows to the top where it escapes. In cold climates the air flow is stopped in order to establish a certain insulation level.
d) The dwelling unit is completed with a door/window frame which is covered with a double-layer ETFE membrane. This aluminium frame is assembled and transported as an entire unit. The sanitary unit is completed with a roof element, an aluminium sheeted rigid-foam panel with a circular opening.
