Construction is in progress at Studio III Architecture’s prototype Passive House! As the foundations get their finishing touches, we reflect on how reality can force upon us design choices we wouldn’t otherwise expect. The original design called for screw pile foundations drilled into the soil as a way to float the main volume above the ground and reduce our carbon footprint by avoiding the use of concrete. Instead, bedrock covers almost all of our buildable area. And so we welcome concrete into our home, whether we want to or not. But at least no one can accuse us of building our house on sand.
