Blueprint: Amphibious Foundation for a Small House — Build Specification

Build specification for a flood-resilient amphibious foundation: a 38,000 kg single-storey house on a watertight buoyant base 10.0 m x 8.0 m x 1.40 m resting on six concrete pads in dry weather and floating up six steel guide posts (168.3 mm x 8.0 mm circular hollow section, 5.20 m tall) when flooded. DESIGN BLUEPRINT - SIMULATED, NOT MEASURED - NOT BUILT, NOT LOAD-TESTED. All performance numbers are from the source paper: lift-off at 0.50 m flood depth, draft 0.475 m, freeboard 0.925 m, rise 2.525 m at the 3.0 m design flood, guide-post bending margin 1.85 at 2.0 m/s current, debris impact margin 1.97, jammed-guide failure at margin 0.13, overtopping at 1.4 m if held down, and hard limits at 3.475 m flood depth, 2.72 m/s current and 987 kg debris.
