Muswell Hill House.

2021

The project entailed the comprehensive structural transformation of an Edwardian mid-terrace house in London, focusing on enhancing energy efficiency and spatial functionality. Key structural interventions included the construction of a single-storey rear extension, which expanded the ground-floor living area. This necessitated the removal of a load-bearing spine wall, replaced by a steel box frame to maintain structural integrity and provide lateral stability. Additionally, a loft extension was undertaken, incorporating a dormer and skylights to create new habitable space on the second floor.

To address thermal performance, the building envelope was upgraded with high-performance insulation and triple-glazed windows, significantly reducing heat loss. An air-source heat pump was installed to provide efficient heating and hot water, complemented by mechanical ventilation with heat recovery (MVHR) systems to ensure optimal indoor air quality and energy conservation. These combined structural and energy-saving measures transformed the property into a low-energy home, aligning with sustainable building practices and modern living requirements.
