The Nighthawk Retreat, an earth-sheltered and solar-powered vacation home near Chelan, Washington, received both the Sustainable Merit Award and the Residential Structures Award at the 2010 Excellence in Concrete Construction Awards. This follows the retreat’s CRSI 2010 Honorable Mention and recent publication in the book “21st Century Houses: 150 of the World’s Best”. Its always nice to know somebody thinks we’re doing something right.
Rather than showing photos of the final design again, here are some construction sequence shots, highlighting the process of cast-in-place concrete construction. It’s interesting to see how much effort went into placing the concrete, most of which was backfilled & buried – never to be seen again. By using concrete and earth as thermal mass, the interior spaces stay cooler in summer and warmer in winter than they would have been if conventional wood-frame construction had been used.
Once again, this project would not have been possible without great clients and the engineering prowess of Quantum Consulting Engineers.
