House Extensions in Kingston upon Thames
Kingston upon Thames offers some of the most desirable family homes in South West London, but growing families often need more space than these properties originally provide. BuildExtensions has been designing and building house extensions across Kingston, Surbiton, New Malden, and beyond for over 20 years — creating beautiful, light-filled spaces that transform how families live.
From rear kitchen-diner extensions with bi-fold doors opening onto Kingston gardens, to two-storey additions that add bedrooms and bathrooms upstairs, our in-house architects and builders deliver seamless extensions that look like they have always been part of your home. We understand Kingston Council's planning policies, building control requirements, and the character of different neighborhoods from riverfront properties to suburban semis.
Whether you live in a Victorian terrace in Surbiton, a 1930s semi in New Malden, or a detached home near Richmond Park, we tailor every Kingston extension to your property's unique style, your family's needs, and your budget. Our fixed-price contracts and dedicated project managers mean no surprises — just exceptional results.
House Extensions Services in Kingston
Rear Extensions
The classic Kingston kitchen extension — extending into your garden to create open-plan kitchen-diners with bi-fold or sliding doors. Perfect for family living and entertaining.
Side Return Extensions
Ideal for Kingston's Victorian and Edwardian terraced houses. We extend into the narrow side alley to create surprising amounts of extra living and kitchen space.
Wraparound Extensions
Combine a rear and side return extension for maximum impact. Popular in Kingston and Surbiton for creating truly expansive ground-floor living spaces with multiple aspects.
Two-Storey Extensions
Add space on both floors — a larger kitchen below and an additional bedroom or bathroom above. The most cost-effective way to add significant square footage to your Kingston home.

Kingston House Extensions FAQs
Do I need planning permission for a house extension in Kingston?
Many single-storey rear extensions in Kingston fall under permitted development rights, but larger projects, side extensions, and two-storey additions usually require planning permission from Kingston Council. We assess your property and handle the application.
How much does a house extension cost in Kingston?
A typical single-storey rear extension in Kingston costs between £60,000 and £100,000 depending on size and specification. Two-storey extensions range from £90,000 to £160,000. We provide detailed fixed-price quotes after your free consultation.
How long does a Kingston house extension take to build?
A single-storey rear extension typically takes 10 to 14 weeks. Two-storey extensions take 14 to 20 weeks. Planning approval can add 8 to 12 weeks. We provide a detailed timeline before work begins.
Can you match the existing brickwork on my Kingston home?
Absolutely. Matching existing materials is essential for a seamless extension. We source reclaimed or custom-matched bricks, roof tiles, and windows to ensure your Kingston extension looks original.
Do you handle building regulations for Kingston extensions?
Yes, we manage the entire Building Control process for Kingston extensions. This includes structural calculations, insulation compliance, fire safety, drainage, and final sign-off certificates.
Can I live in my house during a Kingston extension build?
In most cases, yes. We carefully phase the work to minimize disruption, especially for rear extensions where we can often maintain access to the main house throughout construction.
