The I-House system is based on Celcon Elements – storey-high panels of aircrete that are craned into place on site. Combined with pre-fabricated timber floors and roof system, and constructed by a specialist contracting team, the I-House system can deliver the complete watertight shell of a house on site within a week.
Celcon Elements have been in use in Europe for decades and as long ago as 2007 we used the concept as the basis for zero carbon demonstration projects with both Barratts and Miller Homes.
However, it took a severe skills shortage and a certain amount of government pressure for the housebuilding industry in the UK to start looking seriously at ways to use aircrete in Modern Methods of Construction.
I-House is perhaps the most radical system, so the acceptance by both NHBC and BOPAS is an essential reassurance for users.
We are delighted to see the number of projects using the system growing, with Barratts being an early adopter.
