26 high quality, affordable, Lifetime Homes compliant, healthy, certified Passivhaus flats for social tenants in Exeter.The development, including one fully-accessible wheelchair unit, is aimed at providing downsizing apartments for over-60s, in turn freeing up larger council-owned homes for families in need. Utilising a monolithic clay block construction with high performance render externally and plaster internally means an entirely mineral wall build-up which is hygroscopic, helping to regulate internal humidity. Designed around the large format block coursing, construction time is greatly reduced, drying out period is minimised, and come the end of the buildings life, the construction can be simply crushed up without the need for separation and disposal of composite elements.
