Innovative Battersea Extensions Crafted with Exceptional Architecture
Our Battersea architects create smart, sustainable extensions that suit your space perfectly.
Wraparound
We specialise in wrap-around extensions. This is a popular way to expand and transform properties. This extension combines a rear and side addition. It creates an L-shape that expands ground-floor space. This is ideal for open-plan kitchens, living spaces, or adaptable rooms that fit modern lifestyles. We handle everything from design and planning permission to construction.
Single Storey
A single-storey extension can really boost space in your Battersea property. It can be added to the back or side of the property. This addition offers more space for a modern kitchen, a living area, or a home office. This extension improves the flow inside and makes the property more practical. Our architectural team makes it easy for you to get great results that suit your property.
Multi Storey
A multi-storey extension in Battersea can provide a lot of space. You can use it for extra bedrooms, bigger living areas, or more bathrooms. Building up on your property lets you make the most of it without losing any garden space. We take care of everything. This includes planning, permissions, and construction. We ensure your extension fits well with the current architecture.
Side Return
A side return extension utilises the unused space beside your home. You often find this addon in Victorian and Edwardian buildings in Battersea. Clients can extend into this narrow area to make a wider, open-plan kitchen. This change will let in more natural light. Our architects are experts in side return extensions. These designs boost functionality and add to the property’s value.
Rear Extension
A rear extension expands the back of your property. This gives you room for an open-plan kitchen, a larger dining area, or a more spacious living room. This is ideal for clients looking to improve their ground floor. These extensions boost natural light and link indoor and outdoor spaces smoothly. We create rear extensions that match your home’s style. They also boost efficiency and value.

BATTERSEA — EXTENDING A NEW-BUILD HOME: WARRANTIES, COVENANTS AND THE TEN-YEAR CLOCK (NHBC)
Battersea has a kind of house that barely existed here twenty years ago: the new-build townhouse on a regeneration development.
Those homes are reaching the age where families outgrow them, and we’ve noticed something consistent in how these extension projects begin.
The owners arrive relaxed. Modern house, drawings on file, no Victorian mysteries in the walls — how hard can it be?
Our observation, from the projects we’ve taken through: the architecture genuinely is the easy part.
What catches people is paperwork, in layers a period-house owner never meets, and the pattern of who sails through and who stalls comes down to one thing — whether those layers were opened in week one or discovered mid-build.
Take the warranty first. Most new-builds carry ten years of structural cover, usually NHBC’s Buildmark, and in our experience owners treat it as something that protects the house rather than something that constrains alterations to it. It does both.
Cut into the structure without following the provider’s process and cover on the affected elements can be compromised — so while the clock runs, we treat the warranty as a member of the design team, its requirements sitting alongside the building regs, the new workmanship documented to the standard the original certificate set.
The actual policy terms live in the solicitor’s completion pack, which in our experience nobody has opened since the day they got the keys. We ask for it at the first meeting now, because we learned to.
Covenants are the layer that surprises people most, and we’d say this plainly: assume they exist until the deeds prove otherwise. New estates almost universally require the developer’s or management company’s consent for external alterations, sometimes for a fixed period, sometimes indefinitely, usually alongside a design code on materials and boundaries.
Where the home is leasehold — plenty on these developments are — the freeholder’s licence to alter applies in full, with the Leasehold Advisory Service covering that ground well and the Property Institute’s standards describing how a managing agent’s consent desk should behave. The misconception we correct most often: that planning permission covers all this. It covers none of it.
Each consent is its own key, and we run them in parallel from day one because sequentially they eat a programme alive.
On design, our reading of these estates is that they behave like young conservation areas. The streetscapes were composed — repetition, controlled palettes — and Wandsworth’s officers assess applications against that established character in much the same spirit.
What we’ve watched succeed: matching brick and details where the street can see, ambition spent at the rear. And one technical habit we’d urge on anyone: find out what the house is actually made of before the engineer draws a line. Timber-frame and thin-joint systems junction differently from masonry, and the file knows — so read the file.
Where does it bite if you skip a layer? The sale, years later, when a buyer’s solicitor asks for a consent that was never obtained.
We’ve been brought in to untangle exactly that, and prevention is embarrassingly cheaper. Read the ten-year clock early. It rewards the owners who do.

BATTERSEA — GETTING THE STEEL INTO THE EXTENSION: CRANES, LOGISTICS, TIGHT STREETS (CDM)
Ask us what actually decides the shape of a Battersea extension and the honest answer surprises people. It isn’t planning. It’s often a lorry.
There’s a morning on every one of these projects that the whole street remembers — steel day.
A vehicle the length of three parked cars, a beam that weighs as much as a small van, and a terrace whose side passage is sixty centimetres of bins.
We’ve stood on enough of these pavements to hold a firm view: whether that morning goes smoothly was decided months earlier, at the drawing board, and the projects that treat delivery as a design question never make the street’s group chat for the wrong reasons.
So that’s how we design here. Buildability first. Every structural element gets chosen with its journey in mind, and in our experience the choice comes down to three routes.
Beams spliced — drawn in bolted sections two people can carry through a hallway and assemble in place.
A contract lift over the roof — crane, road closure, permits, lift plan — which sounds extravagant and is sometimes genuinely the economic answer for a heavy package.
Or lighter framing and engineered timber where the engineer’s sums allow it, trading material cost against the logistics bill. We’ve learned not to be ideological about any of them. It’s arithmetic, run at design stage, because a beam drawn without its delivery route is just a problem with a delivery date.
The safety framework agrees with us, as it happens. CDM 2015 exists to make someone own exactly these risks — lifting operations, temporary works, site logistics — and on our projects that coordination sits with the principal designer on the design side and gets managed as a project discipline through construction.
The temporary condition deserves its own respect: the props, needles and load paths while walls are missing get designed to the Temporary Works Forum’s good practice, never improvised, because we’d say the most dangerous hours of any extension are the ones between steel arriving and steel working.
Then the street itself, which we treat as part of the site. Parking suspensions booked with the council weeks ahead.
Notice letters through doors before the first delivery, pavements protected, a banksman who waves pedestrians through with some grace — the Considerate Constructors habits, which in our observation do more for a project’s local standing than any hoarding graphic ever printed. Neighbours forgive noise. They don’t forgive surprise.
And one question we’d urge on anyone comparing tenders, because it separates builders faster than any reference: how does the steel get in? The good ones answer with a method — splice points, crane quote, route through the house.
The others answer with a pause, and that pause is what you’d be hiring.
Steel day done properly takes four hours and produces one photograph and no complaints.
The months of thinking behind it are invisible. On streets this tight, we’ve come to believe that invisibility is what competence looks like.
