built as part of the CobBauge project which brought traditional "cob" techniques up to date and in line with UK building regulations.

£600k!

The article is a bit light on any details to say the least!

Yes, but I was pleased to see that it will probably help self-builders get their plans approved a bit more easily.

Over the years I am sure we have seen lots of people stymied because they couldn't show how traditional techniques complied with rules drawn up for brick, concrete and steel.

From what I can find it has an air source heatpump and an EV charger but no energy efficiency certificate yet. No sign of any solar panels or batteries.

EDIT - A bit more info on the building material here, but only says U value complies with building regulations,

"Experiments were completed to test the best composition of clay and fibre; with hemp and reed coming out top in terms of thermal insulation. The optimum thickness was calculated to be 300mm for both layers of lightweight earth and cob laid side by side. This combines excellent structural stability and a thermal ‘U’ value complying with Building Regulations, all tested in labs in the UK and France."

I found another website which gives a U-value of 0.26W/m²k for the CobBauge.

By comparison, Passivhaus standards are between 0.10 W/m2K to 0.15 W/m2K.
