In the beginning, there was a vision: building a house without heating or cooling. A house offering atmosphere alongside well-tempered interiors at the globally accepted feel-good temperature of 22 to 26 degrees Celsius. 2226: The vision has become reality, the name for the building concept is a promise.

Several projects have already been realized in the 2226 concept.
