The house, designed by CF Møller Architects for the building materials provider Saint-Gobain Isover, is conceived as a playhouse for children and adults or as an unusual guest annex.

Built with an aim to highlight the construction of energy-saving homes, the Playhouse will be exhibited during the climate summit in Copenhagen from December 7-18, 2009. Although small, the house displays details and materials which will be a part of tomorrow’s solutions.

Playhouse is 4.5 meters long and 3 meters tall, and has a distinct leaning profile, with large ‘smart’ glazing windows, skylight and solar panel. The house features an interior lighting that uses a new technology. The walls contain a special, highly insulating glass wool, and the triple-layer energy glazing is equivalent to modern passive-house standards.

The house is so well insulated that a few candles are suffice for heating, even in winter. The skewed form not only looks interesting, it also helps the building’s south facade shade itself from the summer sun.

The walls of the house are not less than 40 centimeter by 40 inches and are filled with a special type of high-insulating glass wool from Isover. An additional advantage of the thick and well insulated walls is that there is hardly escape street noise or other noise from outside.

Panes from the scanner glass are 3-layer energy windows of the most advanced types that are used to modern passive houses. They are designed so that light is released into, but the heat is not allowed to escape.

The house can be experienced live at home business at Highbridge Place in Copenhagen during the entire climate summit from December 7-18, 2009. Saint Gobain is considering to put the house in mass production.

The Playhouse can be won by entering the competition at estate agents home’s website from December 4-17, 2009, or participate in the ‘Climate Vows’ competition on radio Nova FM. Winner drawn will be notified directly.
