River Structures Paul Hirzel
- River House I ‘The Bridge’ with 2,310sqf conditioned space is the living-guest quarters and it sets approx. 12 feet above grade. A 15-foot deep steel Howe truss system spans 80 feet at the center span with 32/16 foot balancing cantilevers at each end. The steel bridge truss supports a wood lattice that shades conditioned space below.
- River House II ‘The Lookout’ with 1,139sqf conditioned space is a multiuse space 1000 feet up river from the main structure. It is constructed with an inverted steel truss exoskeleton which cantilevers 40 feet over the river to view a rare Steelhead spawning pool below.
