Project Etopia is building a development of 31 houses and 16 apartments on a site in Corby, Northamptonshire, using modular prefabricated components.
The superstructures of the first three-storey townhouses were completed in just 34 days, the company says, and the first house — the scheme’s showhome — has now been decorated and furnished.
The homes at Etopia Corby in Priors Hall Park uses a combined heat supply system using solar energy and heat pumps (CHESS SETUP). They have solar panels to generate energy, a GeoStore system to store heat energy and batteries to store electricity. Ground source heat pumps deliver hot water and heating.
The factory-made wall panels have a thermal efficiency U-value of 0.13, which is superior to the 0.16 U-value for a typical well-insulated wall in a new build brick property, Etopia says.
The energy efficiency is expected to similar to the Passivhaus standard.
Community interest company Electric Corby first devised plans for energy self-sufficient homes at Priors Hall Park in 2013, and gained planning permission in 2016. Project Etopia bought the site in 2018 after the project stalled and the company broke ground in December 2018.
