Project Description

Project: Wren Close Affordable Housing
Client: Rosebery Housing Association
Location: Bahram Road, Epsom
Year Completed: 2018
Value: £2.4m (total cost for both projects)
Contractor: Bramber Construction
Architect: David Seaman Partnership

One of two affordable housing projects in Epsom engineered by Gyoury Self for Rosebery Housing Association in 2018. The other project is Mead Court.

The modern housing development is set within a cul-de-sac, providing two two-bedroom semi-detached houses and three one-bedroom terraced houses, delivering a total of five affordable new homes for shared ownership.

The buildings are comprised of load-bearing masonry construction supporting timber floors and timber trussed roof structure, all supported on traditional mass concrete strip foundations.

The Challenges

Gyoury Self undertook all aspects of Structural and Civil Engineering at Wren Close.

This was a tight infill plot, so the biggest challenge was keeping the adjoining boundary walls in place. These were in poor condition and in some instances the new buildings had to be constructed very close to potentially unstable walls.

The unstable walls were first strengthened with galvanised steel posts on the existing concrete slab which was present across the site. This slab was then carefully removed, leaving the perimeter in place to provide temporary support.

The foundations to these areas were also constructed as shallow reinforced beams supported onto isolated pads, to lessen the risk of undermining and possible collapse.
