Hurst Hollow Stilthouse, Austin, Texas

New floodplain rules required this lakeside residence to have 20-foot (6-m) stilts and a continuous ramp to the main level. Steel was selected as the most cost-efficient structural system that could withstand lateral forces 20 feet in the air. Inspired by the systematic approach in premanufactured rigid-frame technology, the stilts were extended into customized rigid-frames whose asymmetry reflects the apportionment of space on the main level.

The 1,653-square-foot (154-m2) residence features 838 square feet (78 m2) of porches. The non-view side of the house features service spaces hugged by an exterior switchback ramp. The remainder of the residence is a large deck that runs the full length of the house, offering broad northerly views of the lake. The frames, expressed on the interior, are tall enough to provide two-story spaces for the main gathering room while allowing the master suite to tuck in above the guest room, laundry and bathroom on the main level.

The residence utilized approximately 4,620 square feet (429 m2) of 24-gauge prefinished double-lock standing-seam steel metal panels by Berridge Manufacturing for the roof and siding.
