Luciano Pia Urban Treehouse

We’re loving this stunning 5-story apartment building in Turin, Italy. Designed by Luciano Pia, this amazing structure helps protect residents from air and noise pollution via 150 trees that absorb close to 200,000 litres of carbon dioxide an hour! Brings a whole new meaning…to the conventional tree house!
