David and Gill’s offsite manufactured sustainable home
David and Gill made the decision to realise their sustainable self-build dream right by their existing home on a conservation site in Hertfordshire. The triangular plot they purchased held a dated bungalow with an awkward footprint, which the couple’s new home, being a replacement dwelling, had to strictly follow. Rising to the challenge, they began work on their low-carbon home based on the high-tech sustainable design put forward by friend and award-winning architect Richard Mitzman of MCMa Architects.
The result of David and Gill’s efforts is a striking timber-framed house inspired by innovation and sustainability. The build’s sloping roof is a clear example of this inspiration, doing much more than simply keeping out the weather: it holds Flextron photo voltaic panels for power generation and a layer of sedum that provides a habitat to wildlife and blends into the surrounding countryside.
Inside, the flooring is 100% recyclable and made from at least 40% recycled materials. The walls are formed by structural insulated panels (SIPs) which are manufactured off-site and offer remarkable insulation and airtightness.
This Modern Methods of Construction (MMC) feature was recognised at the Build It Awards 2020, where the project won ‘Best SIP Home’.
The house is heated using an air source heat pump (ASHP), whilst a mechanical ventilation heat recovery system (MVHR) ensures a constant through-flow of air. Thanks to these technologies, the couple can enjoy the low running costs of their EPC A home with a SAP rating of 97, a much higher score than they originally anticipated.
David and Gill love their new low-carbon home, spacious enough to accommodate their whole extended family in the kitchen/ dining room and enjoy the fantastic views of the surrounding countryside.
Choosing Ecology was a simple decision for them: “…they were the only lender that put a positive value on the ecological benefits the design of our house incorporated”.
