Demonstration Houses

The Homes As Power Stations (HAPS) Demonstration Houses, built in partnership with Tai Tarian and Cardiff University’s Welsh School of Architecture showcase renewable technology within a home. Two 1950’s homes have undergone significant changes to improve and become HAPS homes by having an added heat pump, battery, and solar panels installed. 

The demo houses will be showcased in March 2025 – if you would like to register to visit the properties, please get in touch with HAPS@npt.gov.uk
