Deco House is a London project that transforms a conventional terraced house into a richly articulated Neo–Art Deco interior. Rejecting the subdued material language typical of contemporary extensions, it foregrounds colour, texture, and ornament. Its character is built through a palette of mint and teal greens, cognac and crimson reds, and polished brass, with sculptural curves appearing in the main sweeping staircase, rounded skylights, and gently tiered circular steps.

The original house contained a small rear kitchen extension and suffered from structural subsidence at the back of the building. Limited storage and a narrow floor plan restricted the house’s ability to adapt to the clients’ lifestyle, particularly for one of the homeowners, a private chef whose work required a more generous and functional kitchen environment.

The design increases the overall floor area from approximately 100sqm to 170sqm through a combination of a loft extension, rear ground floor addition including a summer house and internal reconfiguration of the upper floors. A new master suite occupies the loft, complete with an ensuite and separate walk-in wardrobes, while the first floor retains two double bedrooms.

Internally, the spatial strategy focuses on widening the perceived experience of the house. Floors were removed around the stairwell to create a dramatic triple-height entrance hall, supported by new structural ring beams at the upper levels. This vertical space contrasts with a more intimate corridor that leads toward the rear extension, where the floor level drops to create a generous kitchen and dining space with increased ceiling height and stronger visual connections to the garden and park beyond.

Material choices draw from Art Deco precedents and the clients’ existing furniture collection. Glazed ceramic tiles, brass fixtures and warm timber finishes are paired with marble worktops sourced from Scotland, creating a rich yet cohesive interior palette.

The garden landscape forms an important extension of the architecture. An existing above-ground koi pond was integrated into the design alongside a circular summer house used as a home office. Curved pathways and planting establish a dialogue between the kitchen extension, garden pavilion and the open landscape of Pitshanger Park, extending the architectural narrative beyond the house itself.
