Why we chose it
450 mm walls store the day’s heat and give it back at night, so the rooms stay even, with little need for air conditioning.
How it ages
The face softens and the layers show more over time. Wind can wear the surface, so we added a deep roof and a stone base.
Sustainability
Most of the wall came from within 30 m of where it stands. Very little was trucked in.
