The concept caters for both construction professionals and keen amateurs, so that the most cost-effective buildup solution can be found from a range of options, including hybrid builder/client-build programmes.

A high level of insulation ensures buildings will retain a low-variance constant temperature, with low heat takeup in summer, and low heat loss in winter. Humidity levels are maintained through gradual equalisation of indoor and outdoor moisture content, leading to a  constant average humidity within the healthy range.

The building system is deliberately breathable, not hermetic, so it won’t trap moisture and won’t become too arrid.
