Manber Jeffries House

The project reworks a small area of the existing ground floor of the property and provides a new kitchen and dining room that simultaneously operates as a vaulted garden room for the home. The roof lines of the extension fall with 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 height and slope 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 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 an extreme rigour be applied to an informed use of standardised 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 outer façade slide past the steelwork behind when they directly interface with either the host property or the party wall. The exposed steelwork supports a complex roof geometry, and cantilever in two directions to form an elaborate tectonic to the forming of openings to the garden. A deliberate honesty and celebration of stark, layered construction is employed throughout.
