Self-excavation hurricane house

Margot Krasojevic Architecture


The hurricane house is located near the Louisiana coastline which has a history of hurricanes and their destructive effects.
 It is recorded that hurricanes twist around the eye of the storm, always in the same direction which is anticlockwise in the northern hemisphere and clockwise in the South. To determine the design criteria the nature of the hurricane is considered, The scheme uses the hurricane's strength to slowly turn part of the structure along its helicoid retaining wall, burying itself as it turns by using wind direction to mobilize its hydraulic pivots. For this house to withstand environmental loads like winds it must be flexible enough to move with the hurricane, yet provide enough resistance and weight, to dig itself into its own excavated engineered landscape.
The house has a main superstructure which holds the living accommodation, it can move along a helicoid retaining wall, excavating as it does so. The building's core is a reinforced concrete anchor under which a grid of root-like cable foundations spread, pinned into the landscape this anchor supports the superstructure by using a series of hydraulic column lifts which pivot to turn the building, excavating its own substructure as the main living area moves. The architecture is choreographed by the wind direction of the hurricane, turning with it.
The excavated ground is pushed away whilst the artificial island surrounding the building acts as a canopy moving water away from the building.
