We take care of the planning route – from Lawful Development Certificates for three‑metre projects to prior‑approval applications for six‑metre schemes – using our experience with boroughs such as Haringey Council’s planning team, Lambeth Council’s planning service and Brent Council planning to shape proposals around what local councils typically support.
Throughout, we keep communication simple and regular so you always know where your project is and what’s coming next, aiming for a bright, well‑built Paddington extension that quickly becomes the main room everyone uses.

Innovative Paddington Extensions Crafted with Exceptional Architecture
Our Paddington 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 Paddington 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 Paddington 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 add on in Victorian and Edwardian buildings in Paddington. 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.

PADDINGTON — THE BRIDGING EXTENSION: BUILDING OVER THE SIDE PASSAGE (DOC A)
Every surveyor who walks a Paddington terrace clocks it eventually. The house stops. Then there’s a slot — bin width, bike width, the passage running back to the garden. Then next door starts. And above that slot, from the first floor up, there’s nothing at all.
Nothing, in W2. Where nothing costs more per square metre than most of Britain’s somethings.
That air over the passage is the last free site on the block. The bridging extension is the move that claims it: a first-floor room spanning the gap, one flank wall to the other. A study. A bathroom that unjams the whole upstairs plan. The fourth bedroom that quietly changes what kind of house this is when it sells.
Simple idea. The name gives away why it isn’t simple to build. It’s a bridge.
A bridge with a bed in it, resting — and this is the delicate part — partly on structure that isn’t yours.
One bearing on your own flank wall, the other on or beside the neighbour’s, or on a new frame dropped down through the passage.
All of it engineer’s work under Approved Document A, none of it optional, and the party wall process turns up early because building at the boundary and loading shared structures is precisely what that legislation exists for.
The neighbour’s surveyor will want to know exactly how your room intends to lean. Fair enough. It’s their wall too.
Underneath, the passage keeps its day job. Bins. Bikes. The meter reader. Which turns the soffit — the underside of the new room — into the busiest few centimetres on the project: structure, services and fire separation all threaded through it, with lawful headroom and the escape route preserved below.
There are no spare millimetres down there. The drawings behave accordingly.
Planning is a daylight argument, mostly. A new first-floor mass sits close to whatever windows the neighbour has in their flank wall, and where those exist the BRE conventions get applied without sentiment.
Westminster adds the street’s interest: those passage gaps are part of how the terrace breathes, and a clumsy infill is visible from the pavement forever. The consented ones tend to share manners — set back from the front, light or glazed where they face the view down the slot, a room that borrowed the air rather than seized it.
Is it worth the fuss? Look at the ratio. A whole room gained. Zero garden lost. The ground the household already stopped noticing keeps doing what it always did, and a century of useful space gets stacked on top of the bins.
Most London extensions buy space with land. This one buys it with air — and air, remarkably, is still going cheap in Paddington. It’s the only thing that is.

PADDINGTON — KITCHEN EXTENSIONS AND AIR: EXTRACT, ODOUR AND THE DOC F NUMBERS (DOC F)
October fish. Say it to anyone who lives open-plan and watch their face. The sear was worth it. The kitchen looked magnificent doing it. And the smell hit the back bedrooms by nine, met the school uniforms on the landing, and was still hanging around at breakfast like a guest who wouldn’t take the hint.
That house had a kitchen extension somebody designed once.
They all get designed twice, really — it’s just that the second design usually happens by accident. Design one: how it looks. Design two: what it does to the air. Steam off the pasta pot. A dishwasher cycle’s worth of moisture.
Sunday’s bacon. All of it loosed into a room that now connects — gloriously, fatally — to the entire house.
Open plan is a sharing arrangement. It doesn’t ask what you’d like to share.
The rulebook at least puts numbers on the problem. Approved Document F: 30 litres per second extracted next to the hob, 60 if the fan sits elsewhere in the room, background ventilation on top.
Those are minimums. An open-plan kitchen-diner — three rooms’ worth of air wearing one name — is a decent argument for not treating minimums as targets.
But honestly? The numbers are the easy bit. The fights that matter happen behind the hood brochure.
Ducted or recirculating. Ducted. Not a close call — a recirculating hood filters the grease and hands everything else straight back, moisture and all, like a waiter returning your complaint with a smile.
Then the route, which is where kitchens are won: ducting wants the shortest, straightest run to outside the plan can give it, because every bend takes a cut.
So the extract path goes on the architect’s drawings, early, long before anyone’s fondling cabinet samples.
The island hood — everyone’s darling — is the hardest client of all. Its duct has to swim the ceiling void or hide in a bulkhead, and that journey is either a resolved piece of design or the worst surprise of fit-out week. There is no third outcome.
And noise. Nobody budgets for noise, everybody lives with it.
A hood too loud to run delivers nothing whatsoever, whatever the box promised — CIBSE’s ventilation literature counts acoustics as performance, and so does anyone who’s tried to hold a conversation over a cheap fan on boost.
Outside, the molecule still needs somewhere to go, and in Paddington’s packed terraces “somewhere” is a few metres from someone else’s open window.
Discharge positions are chosen for dispersal and for peace — cooking-smell complaints are a whole genre Westminster’s environmental officers could recite from memory, and the prevention is one drawing detail, done once.
Physics wants its refund too: pull serious air out of a well-sealed room and replacement air must be designed in — trickle vents, door undercuts — or the extract will help itself, whistling in through every gap and dead chimney the house has been hiding.
Rigid duct, not flexi, for flow and for cleaning. Building control wants the rates evidenced at the end. Quite right.
The test, though. The test is the same as it ever was. Something ambitious, doors shut, then upstairs an hour later — and the good ones smell of nothing. Absolutely nothing.
Nothing takes drawings. October fish takes care of itself.
