The £2 million scheme – drawing on local vernacular – aims to provide a model for rural developments in the West Midlands

Located on a greenfield site in Callaughtons Ash, Much Wenlock, this £2 million development designed by Architype provides 12 one, two and three-bedroom homes for the South Shropshire Housing Association, of which two are shared ownership and 10 for social rent. With tackling fuel poverty a priority, the housing association decided to follow Passivhaus principles, which can minimise operational costs to around £100 per year for the average house.

Architype, based in neighbouring Herefordshire, has designed the units through ‘investigating the local vernacular’ of Shropshire, working with what it terms a ‘barn aesthetic’. A natural palette of materials sourced locally has been used: clay roof tiles, lime render and hardwood cladding, which has been thermally modified to increase its resistance to decay. Entrances – including entire gables where these contain the main point of access – have been accented with cream-rendered panels.



Architect’s view

The site layout and landscape design was particularly challenging as a result of the steeply sloping site, although with the need for brick retaining structures came the opportunity to broaden the palette of landscape materials. The development was ultimately able to reduce water run-off onto the adjoining road through a wider sustainable drainage strategy.

The houses are arranged around a central shared public green space for use by the new community. Through collaboration with local groups, native tree species and wildflower meadows planting form a central part of the development.
