The project creates a modular form of architecture that latches onto and revitalises derelict buildings, while benefitting the local community. It improves energy efficiency in response to the recent energy crisis by using prefabricated and recycled steel elements, reclaimed construction materials, and retrofit additions. The old Coleg Harlech building is transformed into a recycling plant, training centre, and manufacturing facility for PV panel systems and mycelium insulation.

These two main manufacturing exports are part of a kit that includes HVAC and electrical equipment to enhance energy efficiency in Harlech housing. The modular system allows for easy disassembly and relocation to other communities for continued energy efficiency improvements. The program is supported by trained locals who maintain the equipment.
