Net Zero Modular Homes
Haus4 is an answer to the housing and homelessness crisis. Cyngor Gwynedd Council is using the Haus4One modular homes to house vulnerable homeless people in their region.
These four new homes for Gwynedd Council were built using the Beattie Passive Build System, utilising modern methods of construction, before being transported to the site of an old Roman fort. The scheme consists of four Haus4One units (GIA 24m2) which are all clad in Cedral Click cladding. Each home is equipped with photovoltaic panels to achieve Net Zero in terms of operational carbon emissions.
The modules are a fully bespoke, relocatable solution that can be redeployed according to Gwynedd Council’s changing housing needs. The homes have all been constructed to Passivhaus standards of airtightness and thermal comfort.


With a SAP rating of 104A, each home will save 0.20 tonnes of carbon each year.

Net Zero: the future of housing
The council’s decision to construct Net Zero Passivhaus-standard modular homes represents a significant step forward in sustainable construction in the area. These homes not only offer residents a higher standard of living, but also reduce the environmental impact of housing developments. In this case study, we’ll take a closer look at the construction process and the benefits of these homes for both residents and the environment.
