Douglas Fir Extension Brings Elegant, Light Addition to London Home

The Talbot Road project by Emil Eve Architects is a pavilion-like extension to an Edwardian end-of-terrace house in the Highgate Conservation Area of London. The work creates a large kitchen and a snug that reconnects the home to its garden through a lightweight timber structure.

This extension expresses contemporary clarity while respecting the historic envelope. The design uses a slender Douglas fir frame and a latticed white-stained roof to convey lightness and offer a shaded, outdoor-friendly space.

Concept and design language

The project reinterprets the traditional terrace within a sensitive conservation context. It introduces a lightweight extension that reads as a modern pavilion.

The emphasis is on material honesty and daylight. There is a direct relationship with outdoor space, achieved without imposing on the period façade.

The extension steps down from the main house, orienting the kitchen to the north and the snug to the south. It relies on level changes rather than partitions to delineate spaces.

This strategy creates a seamless flow between indoor and outdoor living. There is a clearly defined sequence from entrance to garden.

Structural expression: timber, roof, and light

The project is defined by a thin Douglas fir frame and a latticed, white-stained roof that extends outward to form a deep pergola. This lightweight structure creates a sense of lightness and helps manage solar gain.

The pergola frames a wrapped patio area that can be enjoyed year-round. A circular skylight and a low wall mark the snug.

The exposed timber roof pattern, along with varied rooflights, modulates light and spatial definition throughout the day. Large sliding windows and doors are framed with slender metal profiles, maximizing transparency and connection to the garden.

Bespoke oak joinery and storage sit beneath the white roof. Externally, ridged ceramic tiles—made from 50% recycled waste—clad the extension, supporting a sustainable, low-impact approach to materials.

• Lightweight Douglas fir frame
• Latticed white-stained roof forming a deep pergola
• Exposed timber roof pattern and rooflights
• Thin metal-framed sliding windows and doors
• Bespoke oak joinery and storage integrated below the roof
• Ridged ceramic cladding with 50% recycled content

Spatial strategy and environmental performance

The kitchen is positioned to the north to optimize daylight. The snug sits to the south, creating different ambiences across the two new spaces.

The design uses level changes rather than walls or partitions to carve out distinct zones. This preserves openness and provides intimate moments for cooking, relaxing, and socializing.

The pergola-like roof modulates light to prevent overheating of the glazed extension and shades the patio. Douglas fir columns rest on in-situ cast concrete feet, which provide weatherproofing and a visual sense of lightness.

The combination of timber, precise detailing, and a restrained palette ensures the extension reads as a contemporary addition that respects the Edwardian envelope.

Craft collaboration and construction approach

Emil Eve director Ross Perkin emphasized a contemporary pavilion concept that still respects period architecture through careful detailing. Close collaboration with the contractor was essential throughout the process.

This approach helped achieve precision in timber joints and roof geometry. It also ensured the integration of new materials with the existing fabric.

Photography for the project is by Taran Wilkhu. The practice—founded by Ross and Emma Perkin in 2009—has completed sensitive London house additions and a Hackney office fit-out.

They are committed to high-quality, contextually appropriate design in urban sites.
