The lake's water levels rise and fall from year to year, requiring a design that floats on top of a steel pontoon raft that automatically adjusts to changing water levels. The house and platform were constructed from prefab parts, assembled on land, then towed to the site and anchored in the water.
The advantages of a floating house include the ability to harness natural heating and cooling from the lake site due to water's vast capacity for absorbing energy. Aquatecture in general also has the potential to be less expensive (no high land payments), more portable, and presents a possible solution to rising sea levels caused by global warming. Drawbacks of aquatecture include practical problems such as sway induced by high waves, the fact that water homes don't have yards or gardens, and unanswered questions about the possibility of damaging environmental side affects.
