Manber Jeffries House is an intricate, single-story, rear, and side extension to the ground floor flat of a substantial, semi-detached, Victorian villa in Willesden Green, London. The project, completed by James Alder in March of 2021, reworks a small area of the existing ground floor of the property and also provides a new kitchen and dining room extension that simultaneously operates as a vaulted garden room for the home.

The roof lines of the extension fall within the internal circulation requirements, allowing the extension to manage the transition from the high level of the existing property’s ground floor to the lower level of the garden beyond. The extension is also designed to fall in height, to match and relate to the steep pitch of an existing lean-to construction, which had previously contained a very small kitchen.

Key to the project was the retention and extension of a substantial brick party wall that had historically supported a symmetrical pair of pitched garden outbuildings and lavatories. These were already semi-demolished and had been heavily neglected in recent decades. Victorian glasshouses and ancillary garden buildings, built as appendages to the boundary walls of formal gardens, formed a particularly strong inspiration for both the formal language and the materiality of the project.

Budgetary constraints demanded that extreme rigor be applied to the informed use of standardized building components to form two contrasting skins that externally and internally line an ambitious structural steel framing configuration. Although heavily interdependent, the openings of the red outer façade slide past the structural steelwork behind when they directly interface with either the host property or the party wall. Demolition of the host property was purposefully kept to a minimum.

The exposed steelwork supports a complex roof geometry and cantilevers in two directions to form an elaborate tectonic to the forming of openings to the garden beyond. A focus on detail and a deliberate honesty and celebration of stark, layered construction are employed throughout.
