House Extensions Surrey: Practical Design from Concept to Completion

Archicraft specialises in designing and delivering house extensions across Surrey, helping homeowners unlock space, improve layout, and add long-term value to their property. Whether you are planning a single storey extension, double storey addition or a full home remodelling project, we provide a practical, cost-conscious approach from initial concept through to final completion.

Our service covers everything from early design and planning drawings to technical specifications, contract administration and on-site project management. This ensures your extension is not only well designed, but fully compliant and efficiently delivered.

Designing a House Extension That Works for Your Home

Designing a house extension is about more than adding space. It is about improving how your home functions day to day. We take the time to understand how you use your space, identifying opportunities to enhance layout, natural light and flow between rooms.

Our architectural design process balances creativity with practicality, ensuring your extension is achievable within budget while meeting planning and building regulations.

We regularly work with homeowners across Surrey, including Woking, Guildford, Epsom, Cobham and surrounding areas, adapting designs to suit both property type and local planning requirements.

Types of House Extensions We Design

We design a wide range of house extensions to suit different property styles, budgets and space requirements.


Single Storey House Extensions

Ideal for expanding kitchens, dining areas or creating open-plan living spaces, single storey extensions are one of the most popular ways to improve your home without major structural complexity.

Rear Extensions

Perfect for properties with available garden space, rear extensions can transform the back of your home into a modern, open-plan environment.

Wraparound Extensions

Combining rear and side extensions, this option offers maximum transformation potential and is ideal for full home remodelling projects.

Double/Two Storey Extensions

A double storey house extension allows you to increase both living and bedroom space, making it a cost-effective option for growing families looking for long-term flexibility.

Side Return Extensions

Common in terraced and semi-detached homes, side return extensions make use of unused outdoor space to significantly improve internal layout.

Garage Conversions

Converting a garage into usable living space is a cost-effective way to add functionality without extending the building footprint.
