The cube-shaped nesting box turns every tree into a design hotel for architectural orientated birds. The outer covering made from stainless or rusted weatherproof steel serves as a rain shelter. Inside the birds find a cozy, species-appropriate room made entirely from wood. The steel cover does not lie against the wooden interior so that the air can circulate well in between. A very likable product that for sure makes winged friends feel comfortable and that offers pleasant calm aesthetics to the eye. Would say: perfectly balanced modern architecture with the potential to become a classic.
