Best No Sweat No A / C Eco House

The Main Stay by Matt Fajkus Architecture

Mixing indoor and outdoor elements – the entire living room opens up on a bright blue lap pool – MF Architecture's Main Stay House is certainly easy on the eyes. But it's also easy on the environment. The six-year-old firm's design embraces nature in a way that makes us wanna be outdoorsy from the moment we walk in the front door.
