Transform-ER Pilot, 156 Parsloes Avenue
Four-week full-home retrofit of a social-rented house under the Transform-ER pilot, run by Energiesprong UK. A kit-of-parts approach combines a prefabricated EWI facade, thermally broken structural connections, solar PV with battery storage, mechanical ventilation and waste-water heat recovery. Post-retrofit EPC raised to A 93.

156 Parsloes Avenue is a social-rented home in Dagenham on the Transform-ER retrofit scheme run by Energiesprong UK. The pilot set out to show that a full-home retrofit could be delivered in four weeks, using an innovative kit-of-parts methodology and bespoke, thermally broken structural elements that connect through the external wall insulation (EWI) facade.
What the drawing package covers
The issued set runs from survey through to a loft schematic and sequence of works: ground, first and loft plans, north and south elevations, a services elevation showing the I-beam support structure, plus the special details that make the retrofit tricky — rear door thresholds, loft chimneys and the roof eaves detail.
Services & fabric upgrade
The retrofit combines a prefabricated EWI envelope with 6.23 kWp solar PV and battery storage, mechanical ventilation and waste-water heat recovery. The thermally broken structural connections eliminate thermal bridging and maintain airtightness, allowing high-volume, industrialised retrofits without compromising building physics or tenant comfort.
