Budapest University of Technology and Economics' ODOO project is " a small house with an intensively used outdoor living area. The Odoo is a design concept to create a new type of living space which combines the benefits of traditional Hungarian lifestyle and modern, contemporary comfort conditions. "
This house has a really seductive plan, with an outdoor court integrated into the design. It also has an interesting system of water storage and circulation that keeps it cool in summer with sprinklers on the roof, and warm in winter with a radiant floor system tied into storage tanks to gather heat passively and release it later.
