London Extension 108 | Connecting Split Levels Through Light, Oak, and Section

Applied products
View all applied products

A modest Victorian terrace in Southwest London is restructured through a quiet but deliberate series of sectional and spatial moves — anchored by a timber-framed glass extension and a lowered reading nook carved into the undercroft. The project reorganises the home’s split-level plan into a sequence of connected, calm, and functional volumes, reflecting a family’s need for togetherness without sacrificing moments of retreat.

The brief came from a family of five seeking a better balance between connection and separation — a layout that would support cooking, eating, working, and resting without relying on full open-plan living. The house’s existing configuration placed the kitchen at the lower rear, the living room at the front, and a generously sized central room in between that lacked a clear role. The design challenge was to turn this middle space from a transitional zone into a core part of daily life.

The first intervention infilled the narrow side return with a timber-framed glass extension. A deep seating nook subtly projects into the garden, offering a place to sit, dine, and look out. This gesture opened the kitchen to the garden and created a warm enclosure that draws light deep into the plan.

The more transformative move looked inward. By lowering the floor of the central room into the undercroft, the design created a sunken reading nook that connects directly to the kitchen below, eliminating excess circulation and stitching the ground floor together in section rather than in plan. This reconfigured middle zone gains borrowed light from both ends of the house and a retained window above, making it a bright and defined place to pause.

Oak was used consistently — in glazing frames and bespoke joinery — to bring warmth and continuity across the new and existing spaces. The reading nook is framed with storage, lined in oak, and acts as both a retreat and a connector. Many of the interior elements were developed in close collaboration with the client, whose strong design sensibility helped shape the tone and detail of the final space.

The result is a compact but highly resolved reconfiguration — achieving connection through section, comfort through material, and clarity through a set of quiet, deliberate decisions.
