London Townhouse powered by an Air Source Heat Pump | Architects for Hackney | forrester architects

This ambitious London townhouse reconfigurationt redefines the traditional London townhouse layout for modern living, integrating an Air Source Heat Pump for sustainability.With rising energy costs, improving thermal efficiency was a priority. The project eliminates reliance on a gas boiler, enhancing insulation and overall energy performance.

At the heart of daily life will be a spacious, open-plan lower ground floor. Designed for light and space, it centres around the Danish made kitchen units, lounge, and dining area. The kitchen sits in a striking double-height space, created by removing part of the raised ground floor. A new mezzanine connects to a metal staircase leading to bespoke Danish-made kitchen units, the dining area, and the extension. The highly insulated timber-framed rear extension features a distinctive pyramidal roof with a large glazed top light, offering uninterrupted sky views. Beyond it, a new garden studio provides a dedicated workspace, mirroring the extension’s insulation for consistent energy efficiency.

On the top floor, a full roof rebuild includes a rear dormer conversion, maximizing insulation while preserving floor space. Custom-made wardrobes make use of generous roof voids in each bedroom. To cut electricity use, solar PV panels on the dormer roof support a sustainable energy strategy, reducing the home’s overall environmental impact.
