The high levels of energy efficiency of this Passivhaus scheme has helped the housing association provide its tenants with affordable, low-energy accommodation.

Callaughtons Ash is a residential development of 12 homes located at Much Wenlock in rural Shropshire. The South Shropshire Housing Association wanted low energy housing for its tenants, appointed Architype, one of the UK’s leading architectural studios specialising in low-energy design.

The development comprises of  10 socially rented and two shared ownership properties with a mix of one-three bedrooms. 

Working with Lowfield Timber Frames, Architype designed these timber-clad homes to meet the Passivhaus Standard, which involves very high levels of insulation and airtightness so that buildings use very little energy for heating and cooling.

Lowfield Timber Frames translated the Architype’s design to create a fully bespoke timber system that would meet the high levels of energy-efficiency required to gain Passivhaus certification. Achieving this, minimises operational costs to below £100 per annum for average housing types, and so meet housing association’s core value of providing affordable, low-energy accommodation for local people.

The South Shropshire Housing Association and local community was consulted about the design, which reflects the rural local vernacular and are clad in locally sourced materials. This includes clay roof tiles that have been quarried and made within 25 miles of the site; lime render provided by local company Lime Green and; UK grown thermally modified hardwood cladding.

Together, the design promotes the housing association’s aims for a cohesive circular economy in Shropshire.
