Our Services For Wraparound
extensions in London:

Due to their complex hybrid structure, courtesy of the combination of a side and rear extension that wraps around the back of the home, forming an L-shape, a wraparound extension is quite unique as an extension form. They incite a certain degree of architectural interest, facilitating an expansive space, unlike any other extension form in comparison. That being said, they also pose structural complications, higher costs, and may also give rise to boundary disputes, hindering natural light and triggering the party wall act with neighbours if not managed well.

While London is cramped for urban space, for the very same reason, a wraparound extension is also the desired form that can effectively utilise a previously dead space, to give rise to multifunctional and expansive living areas. As a London-based practice, Extension Architecture understands the arc of London’s geography and aesthetic considerations, along with the unique challenges of the city’s properties that vary as narrow plots, heritage considerations, and planning constraints. Whether you’re looking to build a spacious family kitchen, add natural light through skylights and bi-fold doors, or achieve a seamless indoor-outdoor flow, through our design-and-build approach, our experts ensure a wraparound extension that’s a thoughtful reinvention of how you live.

What our Clients are Saying

Here's what some of our clients have to say about working with us, their stories reflect the trust, value, and impact we strive to deliver in every project.

Our process of building a Wraparound Extension

Our process of building a wraparound extension begins by understanding your vision and assessing your property’s potential, followed by drafting bespoke plans that seamlessly blend the new structure with your existing home. Our architects curate designs that blend with the existing design, a critical step that involves either remaining synonymous or creating contrasts with aesthetics. Factors such as adjoining properties, considerations to maximise natural light, and London’s strict planning regulations are all tabled and envisioned.   From design concept to material selection and execution, we consume the complete baggage through our design and build approach that involves timely coordination between architects, engineers, and builders to realise a visually cohesive and structurally lasting extension.

A double storey wraparound extension not only maximizes your floor area but also reshapes how you live and connect within your space by providing the best of both worlds. You can not only enjoy a larger, open-plan ground floor for contemporary living & entertaining, but also take advantage of additional upper-floor space as bedrooms or leisure areas making it ideal for growing families. Beyond functionality, a wraparound extension enhances architectural harmony by blending tradition with modern design seamlessly.

Yes, and most certainly, as wrap-around extensions always exceed the rules of permitted development with their unique side and rear combination.
In London, the cost of a wrap-around extension may range from £70,000 to £1,30,000, while in the UK, the costs are lesser priced and start with £60,000, going up to £1,20,000.
Absolutely, and with great success. As semi-detached spaces often have one dead space to the side and a garden to the back, they are ideal candidates for a wrap-around extension. with terraced properties, the side-return is often narrow, and a wrap-around can fill this space, extending further back into the garden.
Often, a wrap-around extension is considered a great extension prospect that increases property value by up to 15-20%. 
Because Extension Architecture exclusively specialises in bespoke extensions, we are seasoned specialists in accommodating maximised space, natural light, and functionality while complementing your property’s character. With a design and build approach, we curate from initial concept and planning approvals to precise construction, with meticulous attention to detail. We also boast of a track record of delivering high-quality, structurally sound extensions on time and within budget.
