House extensions across Ealing, West Ealing, Hanwell and Acton from £34,000 inc. VAT.
Side returns for Edwardian terraces, wrap-around and two-storey extensions for 1930s semis — with conservation area checks, planning, party wall notices and building control handled for you.
Vita Modular builds house extensions in Ealing — side returns, rear kitchen extensions, wrap-arounds and two-storey extensions for the homes of W5, W13, W7 and beyond — from £34,000 inc. VAT. Ealing earned the name "Queen of the Suburbs" around 1902, and its streets still show it: Edwardian terraces in West Ealing, Northfields and Hanwell, and long runs of 1930s semis towards Greenford and Perivale. Those two house types extend in different ways, and we design for each.
Planning in Ealing is address-specific. As at 2026 the borough has around 29 conservation areas, from Bedford Park and Brentham Garden Suburb to Ealing Green, Montpelier and Hanwell Clock Tower, and a 2024–25 review redrew the boundaries of around 20 of them and added a new one at Lammas Park. A house that sat outside a conservation area two years ago may now be inside one. We check your address against the council's current records before any design work begins.
Every extension is 100% bespoke and sold at a fixed, all-inclusive price. The structural steel frame and insulated panels are manufactured at our Warwickshire facility while your foundations go in, then assembled on site by our own teams with no crane or heavy lifting. Most London extensions are built on site in 4–6 weeks.
In Ealing, extending usually costs far less than trading up. The borough's average house price was £541,772 in November 2024 (Land Registry), up 31.1% in ten years, so moving to a bigger home means a large price gap plus stamp duty, fees and removals.
Stay on the street you chose. Families often buy in Ealing for its parks, schools and transport, then outgrow the house. A 15 m² rear extension starts from £45,000 inc. VAT and a 21 m² wrap-around from £63,000, which buys the open-plan kitchen and family room most buyers want without leaving West Ealing, Northfields or Hanwell.
Two house types, two good answers. Edwardian terraces have a rear outrigger with a narrow, shaded strip beside it — the classic side return. Many of Ealing's 1930s semis have side access instead, which leaves room for a wrap-around that turns the corner of the house, or a two-storey extension that adds a bedroom as well as a bigger kitchen.
Added value, not just added space. Industry analysis puts a quality extension at around £1.50 of added value for every £1 spent, typically £1.40–£1.60. Side returns to period terraces are among the strongest performers, which suits the Edwardian streets of W5, W13 and W7.
Less disruption on residential streets. Our frame and panels are made off-site and carried in by hand, with no crane and no heavy plant. That suits mid-terraces with no rear access, narrow side returns and sites reached only through the house, and it means fewer deliveries on streets where parking is tight.
A fixed price agreed before work starts. The price covers foundations, the structural steel frame, external walls, silicone render, flat roof, painted walls and ceilings, electrics and lighting, flooring and up to 3m-wide aluminium or uPVC doors and windows. Demolitions, ground preparation, drainage, professional fees, statutory approvals and new structural openings are itemised separately.
River Brent homes checked first. Parts of Hanwell and Perivale and stretches of the Brent valley lie in Flood Zones 2 and 3 because of the River Brent and the Grand Union Canal. If your home is near either, we check its flood zone at the survey so any flood risk assessment or flood-resilient detailing is planned from the outset.
The planning authority for house extensions in Ealing is the London Borough of Ealing, and its householder guidance is SPD 4 Residential Extensions. Whether you need full permission depends mainly on whether your address is in a conservation area or covered by a householder Article 4 direction.
As at 2026, Ealing has around 29 conservation areas. They include Bedford Park in W4, often described as the world's first garden suburb, which straddles the boundary with Hounslow; Brentham Garden Suburb, the Arts and Crafts estate near Pitshanger; Ealing Green and Montpelier in W5; and Hanwell Clock Tower and St Mark's Church & Canal in Hanwell. A 2024–25 review changed around 20 areas — most were extended, some reduced — and designated a new Lammas Park conservation area. Pitshanger and Northfields are neighbourhood names, not conservation areas in their own right, so the check has to be made by address.
Inside a conservation area, permitted development rights are reduced. Side extensions, which include most side return infills and the side part of a wrap-around, need full planning permission, and the larger home extension prior approval route is not available.
Ealing's borough-wide Article 4 direction, confirmed on 11 July 2025 and in force since 14 November 2025, removes the permitted development right to change a house (use class C3) into a small house in multiple occupation (C4). It covers the whole borough except Perivale ward and the OPDC area. It is often mistaken for a restriction on building work, but it is not: it does not affect ordinary house extensions. A family adding a kitchen extension to their own home is unaffected by it.
Separate Article 4 directions in some conservation areas, Bedford Park among them, remove specific householder permitted development rights. These follow individual properties, so we confirm the position for your address with the council rather than relying on a street map. Our guide to planning permission and Article 4 in London explains how these directions work.
Outside conservation areas, and where no Article 4 direction or planning condition applies, a single-storey rear extension on a terraced house or semi can generally project up to 3m from the original rear wall without an application, with a maximum height of 4m, or up to 6m through prior approval with neighbour consultation. Two-storey extensions in Ealing will usually need a householder planning application. Building control approval is needed for every extension, and we manage it through to sign-off.
We check your address against Ealing's conservation area and Article 4 records and the Environment Agency flood map before you commit, then prepare and submit the application, manage building control approval and serve party wall notices as part of the turnkey service. Planning information is accurate as at 2026 and is general information, not planning advice.
Roughly half or more of Ealing's homes are terraced and around a third semi-detached, on indicative figures — and the right extension depends on which you live in.
Edwardian terraces — West Ealing, Northfields, Hanwell. The Edwardian terraces of West Ealing (W13), Northfields and Little Ealing, and the Victorian and Edwardian streets of Hanwell (W7), share the familiar outrigger and side return. A side return extension squares off the back of the house and turns a galley kitchen into a full-width room. Acton (W3) and Southall (UB1/UB2) have similar period terraces, alongside many flat conversions.
Ealing Broadway, Ealing Common and Pitshanger — W5. Victorian and Edwardian villas and terraces around Ealing Broadway and Ealing Common, and Edwardian and Arts and Crafts houses in Pitshanger and Brentham. Several streets fall within Ealing Green, Montpelier or Brentham Garden Suburb, where materials, roof form and glazing are judged closely, so we detail brick, render and glazing to suit the house.
1930s semis — Greenford, Perivale, Northolt. In UB6 and UB5, and in parts of Hanwell, the typical home is an interwar semi with side access. That space suits a wrap-around extension wrapping a new kitchen round the side and rear, or a two-storey extension that adds a bedroom above. Two-storey work normally needs a householder application, which we prepare.
Bedford Park — W4 edge. The Ealing side of Bedford Park has red-brick garden-suburb houses under conservation area and Article 4 controls. Extensions here are possible, but many need a planning application and a careful, well-matched design; we check the Article 4 position for your address. Ground-floor flats with garden rights anywhere in the borough also need full planning, as flats have no permitted development rights.
House extensions in Ealing start from £34,000 inc. VAT, at £3,000 per m² all-inclusive. A 12 m² side return starts from £36,000, an 18 m² rear extension from around £54,000, a 21 m² wrap-around from £63,000 and a 30–40 m² two-storey extension from £90,000. Traditional London builders often reach £3,800 per m² or more once VAT, glazing, electrics, flooring and decoration are added.
Where Ealing adds cost. Conservation area homes in Bedford Park, Brentham or Ealing Green need a planning application and design-led drawings, and matched brick or conservation-style glazing adds to the specification. Homes in Flood Zones 2 or 3 near the River Brent may need a flood risk assessment and flood-resilient details. Opening up the back of a period terrace usually needs a new structural opening, quoted separately.
Where it stays efficient. A rear-only extension on an undesignated terrace or semi can often go ahead under permitted development, avoiding an application fee and wait. Our no-crane method keeps access costs down on mid-terraces where materials have to come through the house.
Comparing like with like. A typical 18 m² rear extension from a traditional London builder comes to around £68,400 or more once everything is included, against around £54,000 inc. VAT from us. Traditional builds also often take 10–16 weeks or more on site, compared with an average of around 6 weeks for ours. See our London extension cost guide for the full breakdown.
What our price includes. Foundations, structural steel frame, external walls and silicone render, flat roof, painted walls and ceilings, electrics and lighting, flooring and up to 3m-wide aluminium or uPVC doors and windows. Optional extras such as roof glazing, canopies, kitchens and underfloor heating can be added in the quotation form.

These completed Vita builds come from projects across the UK and show the sizes and fixed prices behind an Ealing extension. The borough's 1930s semis usually have side access and wider plots, so full-width rear, wrap-around and two-storey options all come into play.

We build house extensions across the whole London Borough of Ealing — W5, W13, W7, W3, the W4 edge and UB1, UB2, UB5 and UB6. Every project starts with an address-specific planning and flood check.
Industrial land on the Park Royal fringe falls under the Old Oak and Park Royal Development Corporation rather than Ealing for planning, and Bedford Park straddles Ealing and Hounslow — we check which authority covers your address. We also build across neighbouring Hammersmith & Fulham and Richmond .
What homeowners in Ealing, West Ealing, Hanwell and Greenford ask most about planning, cost and building on a terrace or semi.
It depends on your address. As at 2026, Ealing has around 29 conservation areas, and inside them side return infills, wrap-arounds and larger rear extensions need full planning permission. Outside them, a single-storey rear extension on a terraced or semi-detached house in Ealing can usually project up to 3m under permitted development, or up to 6m through prior approval. Two-storey extensions usually need a householder application. Building control approval is needed in every case, and we check your address with the council before design starts.
No. Ealing's borough-wide Article 4 direction, in force since 14 November 2025, only removes the permitted development right to convert a family house into a small house in multiple occupation. It applies across Ealing except Perivale ward and the OPDC area, but it does not affect ordinary house extensions. Your rear, side return or wrap-around extension follows the usual permitted development and conservation area rules. Separate Article 4 directions in some conservation areas, such as Bedford Park, can remove householder rights, so we check your property individually.
Possibly, even if it was not before. Ealing's 2024–25 review changed around 20 conservation areas, extending most, reducing some and creating a new Lammas Park conservation area. Established areas include Bedford Park, Brentham Garden Suburb, Ealing Green, Montpelier, Hanwell Clock Tower and St Mark's Church & Canal. Pitshanger and Northfields are not conservation areas by name. Boundaries follow individual properties, so we confirm your exact address with Ealing Council before any drawings are prepared.
Our side return extensions in Ealing start from £36,000 inc. VAT for 12 m², at £3,000 per m² all-inclusive, covering foundations, steel frame, walls, roof, glazing, electrics, lighting, flooring and decoration. A larger 21 m² wrap-around starts from £63,000. Traditional London builders often reach £3,800 per m² or more once the same items are included. Drainage, demolition and any new structural opening are quoted separately, and our instant quotation form gives an itemised fixed price for your Ealing home in minutes.
Both suit the 1930s semis common in Greenford, Perivale, Northolt and parts of Hanwell, because many have side access. A wrap-around uses that side space and the rear to create a large kitchen-family room, from £63,000 inc. VAT for 21 m². A two-storey extension adds a bedroom too, from £90,000 for 30–40 m². In Ealing, two-storey work and side extensions in conservation areas usually need planning permission, which we prepare and submit as part of the service.
It can. The River Brent and the Grand Union Canal put parts of Hanwell, Perivale and the Brent valley in Ealing into Environment Agency Flood Zones 2 and 3, and there is a flood warning area for the River Brent in Ealing. Homes in those zones may need a flood risk assessment with the planning application and flood-resilient details. Flood risk is address-specific, so we check your property's flood zone at the survey and design for it from the start.
In most cases, yes. Most homes in Ealing are terraced or semi-detached, so a side return, rear or wrap-around extension usually involves building on or near a shared wall, and the Party Wall etc. Act 1996 applies. Notices must be served on adjoining owners before work begins. We serve the notices, coordinate surveyors where a neighbour appoints one, and fit the process into your programme so it does not hold up your start date in Ealing.
Once your order is placed we offer a guaranteed 4-week lead time to start on site, subject to any planning permission or prior approval being in place. Where planning and design are needed, that stage typically takes 8–10 weeks first. The frame and panels are manufactured at our Warwickshire facility while foundations go in, so most Ealing extensions are built on site in 4–6 weeks, compared with 10–16 weeks or more for a traditional build.
