Project
RAHIP Enfield is a deep-retrofit pilot of 10 houses delivered with Osborne Property Services. The approach was fabric-first, later extended to door and window replacement, roof and loft ventilation, and an air-source heat pump with solar PV, bringing the homes up to EPC A.
Ventilation detail
A bespoke vent box was designed to sit on the rear wall, containing all the ventilation equipment and protruding only 100 mm from the external wall. This allowed the services to run externally without entering the house and became a successful part of the retrofit.
Scope
The drawing set covers Archetype 10A at 26 Deansway, documenting the existing and proposed house through plans, elevations, 3D views, construction details, and coordinated ventilation, electrical and plumbing drawings. Site photos record the retrofit in progress.
Role
Technical Designer — Retrofit, working across the existing and proposed drawings, the services coordination, and the construction details for the project.
