Project Location

Cobham is not an ordinary village. Known internationally as the home of Chelsea F.C.’s training ground, it has evolved into one of Surrey’s most prestigious addresses attracting international residents and high-net-worth homeowners who expect architectural excellence. The atmosphere is sleek, refined and technologically advanced.

At Extension Architecture, we design to meet this standard. With over 16 years of experience delivering residential and commercial projects, we understand the precision and discretion required in Cobham. From bespoke super-villas to carefully detailed extensions, we unlock complex sites while navigating planning policy strategically.
Our architects and designers oversee every stage from concept design and planning applications to technical detailing and coordination. We serve homeowners and developers across KT7, KT8, KT10, KT11, KT12 and KT13, delivering architecture defined by confidence, innovation and enduring quality.

Kensington is not simply a postcode; it represents heritage, prestige and architectural distinction. From white stucco terraces to grand Victorian townhouses, the district demands design that respects history while embracing modern refinement.
At Extension Architecture, we design within this context. With over 16 years of experience across residential and commercial projects in Kensington, our team understands the discretion, precision and planning intelligence required here. Complex sites, listed buildings and conservation constraints are approached not as obstacles, but as opportunities for thoughtful architectural expression.
Our architects, project managers and interior designers oversee every stage from concept design and planning strategy to technical detailing and construction coordination. We serve homeowners and developers across SW3, SW5 (part), SW7, SW10 (part), W8, W10 (part), W11 and W14 (small part), delivering architecture defined by quality, longevity and understated luxury.

Oxshott is defined by privacy, scale and architectural presence. Set behind private roads and expansive plots, this is a landscape of monumental homes where proportion and symmetry matter as much as craftsmanship. Architecture here is not modest but it is composed, confident and enduring.

Coombe is defined by seclusion, prestige and architectural restraint. Hidden behind mature trees and private roads, it is one of southwest London’s most exclusive residential enclaves, where homes sit on expansive plots and privacy is paramount.

Richmond demands a considered and highly coordinated approach to design. We provide a complete architectural service, managing every stage from initial concept through planning, technical design and construction support.
Our work spans substantial detached homes, refined period terraces and riverside properties across TW1, TW2, TW9, TW10, TW11, TW12, SW13 and SW14. Each project begins with a strategic understanding of site, heritage context and planning constraints.
We integrate architectural design, planning applications, building regulations and consultant coordination under one structure, ensuring clarity and continuity throughout. This reduces risk, strengthens decision making and protects long term value.
In Richmond, success lies in precision and restraint. Our role is to deliver a seamless process and a finished result that feels entirely aligned with its setting.

Fulham requires a precise and highly coordinated architectural approach. We provide a complete service across W6, W12, W14, SW6, SW10 part, W10 part and NW10 small part, managing every stage from concept design through planning applications, technical development and construction support.
Our work spans Victorian and Edwardian terraces, lateral apartments and riverside properties, each demanding careful spatial strategy within often constrained urban plots.
By integrating design, planning, consultant coordination and regulatory approvals under one structure, we ensure clarity and continuity throughout the process. This cohesive approach protects programme timelines and strengthens decision making. In Fulham’s competitive property market, architecture must do more than add space. It must elevate proportion, light and long term value while preserving the composure of the surrounding streetscape.

Esher is characterised by substantial detached homes, private roads and generous plots that demand a confident yet disciplined architectural response. We provide a complete architectural service across KT7, KT8, KT10, KT11, KT12 and KT13, guiding projects from initial concept through planning, technical design and construction coordination.
Our work ranges from refined extensions to complete redevelopment of large family residences. 

We also undertake select projects across wider Surrey locations including Farnham, Godalming and Haslemere, where larger rural plots and countryside settings require a similarly disciplined architectural approach.
By integrating architectural design, planning strategy and consultant coordination within one structured process, we ensure clarity at every stage. In Esher, scale alone does not define success. Proportion, material quality and spatial hierarchy are critical. We approach each project with a strategic understanding of site context, local planning policy and long term value, delivering architecture that enhances both the property and its setting with confidence and permanence.

Our portfolio in Weybridge includes large scale extensions, internal reconfigurations and bespoke new build residences. By coordinating design, planning applications and technical consultants under one framework, we ensure continuity and efficiency throughout. In a location where property value and presentation are closely linked, architecture must be both aspirational and disciplined. We focus on proportion, spatial hierarchy and material refinement to deliver homes that strengthen long term value and architectural presence.
