The Formosa house is an amphibious house, designed by Baca Architects, that responds to floods by embracing them rather than trying to fight back. The house is capable of floating on floodwater before being gently restored to ground.
The house includes four vertical posts or 'dolphins' that guide the house upwards in a stable manner when the water level rises. The house's structure also includes a concrete base and sufficient ballast for stability. The house's facilities utilize flexible pipes that continue to operate during and after flood events.
The Formosa house is located 10 meters from the River Thames in Buckinghamsire, U in a designated flood zone. This area is considered at high risk of flooding but is also designated as a functional floodplain where water must be permitted to flow during times of flooding, making it an ideal location for this amphibious house.
