The Hildreth Residence occupies a steep hillside site above the Girdwood valley floor, with a clear view corridor across the valley to Turnagain Arm and the Kenai Mountains beyond.
The heavy timber primary structure is engineered for 130 psf snow — Girdwood's extreme design year condition — with moment-frame connections at the entry that allow the large glazed opening without reducing structural capacity.
Triple-glazed wall units with thermally broken frames maintain a wall assembly U-value below 0.10, meeting passive house targets for a building of this size in this climate.
