Net Zero modular homes from our popular Haus4 range

Haus4 is our answer to the housing and homelessness crisis. Cyngor Gwynedd Council is using our Haus4One modular homes to house vulnerable homeless people in their region.

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

Project Description

We built these four new homes for Gwynedd Council at our offsite factory using modern methods of construction, before transporting them 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.

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.

The advantages of offsite manufacturing

Modular construction was chosen for this housing development due to its speed, cost-effectiveness, and operational efficiency. The homes were constructed offsite at our factory, allowing for more precise construction and reduced waste. The use of prefabricated components also made it possible to construct the homes in a shorter time frame than traditional homes.

The homes were built to the Passivhaus standard and, as such, are designed to be highly energy-efficient. The walls, roof, and floor are all super-insulated as a result of our patented build system, and the windows were triple-glazed to prevent heat loss. The homes are all fitted with MVHR, which helps to improve indoor air quality.

The benefits of the scheme

The construction of these Net Zero modular homes brings a host of benefits to the council, its tenants and the environment. For residents, the homes provide a high standard of living, with comfortable indoor temperatures, improved indoor air quality, and reduced energy costs. The use of renewable energy systems means that residents will have access to clean, sustainable energy that will significantly reduce their energy bills and help to combat fuel poverty.

For the environment, the construction of these homes represents a significant step forward in sustainable construction. The energy efficiency of our structural thermal envelope results in an attendant decrease in carbon emissions and the use of renewable energy systems means that the homes have a very low environmental impact. In addition, modular construction by definition reduces waste and lowers the overall carbon footprint of the housing scheme.
