Loft Conversions · W5 Ealing
Ealing applies conservation control across several W5 villa suburbs; the large plots make rear and side extensions a strong local market.
This page covers one part of the borough. For the full picture — fees, timelines and the council's current position — read loft conversions in Ealing.
A loft conversion in Ealing usually takes the form of a rear or L-shaped dormer on W5's terraced houses, or a hip-to-gable plus dormer on the semi-detached and villa stock. Ealing Council assesses roof additions on design and street impact, particularly near Ealing Green, Montpelier, Pitshanger, Mount Park; we confirm whether your loft is Permitted Development or needs full planning, then handle the drawings, structural calculations and Party Wall notices.
Every loft type across every Ealing roof line — dormer, mansard, hip-to-gable, L-shape, Velux. LDC or full planning route, building regulations, structural calculations and party wall notices, all fixed price.
Across Ealing, Ealing Broadway, Pitshanger, Montpelier in W5, the dominant property is substantial edwardian and victorian villas and semis, inter-war housing and mansion blocks across ealing, 'queen of the suburbs'. That stock shapes what loft conversion drawings looks like here: the right approach for a period terrace differs from a mansion-block flat or a new-build, and Ealing Council judges each on design quality and neighbour impact. We survey the specific Ealing property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the W5 streetscape.

Because W5 is full of substantial Edwardian and Victorian villas and semis on generous plots around Pitshanger and Montpelier — ideal for rear, side and double-storey extensions and large loft conversions as families grow. We've drawn the full range here to Ealing's standards, on both Permitted Development and full-planning routes.
Ealing Broadway on the Elizabeth line has cut journey times across London, reinforcing W5's status as a premium family suburb and supporting values. For a house project the binding controls remain Permitted Development limits and the local conservation designation, which we check for your road.
Often, yes. The larger semis and detached houses around Mount Park Road and Castlebar Road have the plot and separation for a two-storey side or rear extension, subject to Ealing's design and neighbour-amenity policy. We design within those limits and draw the scheme for planning and Building Control.
Ealing Green, Montpelier, Pitshanger and Mount Park all carry conservation designations within W5, controlling materials, bays and roofscape. We check your exact address, because it determines whether you need full planning and a Heritage Statement rather than a Lawful Development Certificate.
With Ealing property at around £450,000 for a flat and £900,000-£1.4m for a house, the professional drawing fee is a small fraction of the value the work adds to W5's substantial edwardian and victorian villas and semis.

We quote the drawings as one fixed price and the free site survey covers every W5 address.

Almost always. Any structural work behind loft conversion drawings in Ealing — new openings, steel beams, loft floors, foundations — needs Building Regulations approval covering structure (Part A), fire escape (Part B) and insulation (Part L), submitted to Ealing Council Building Control or an approved inspector. On W5's typically terraced and semi-detached stock, a Party Wall notice to adjoining neighbours is normally required before the steelwork. We coordinate both as part of the Complete package.
In value terms, yes. The bigger risk is an unapproved or non-compliant scheme — which is why council-ready drawings and a clean Building Control sign-off matter on W5 homes.
Planning history and precedent stop at the borough line, so the comparable approvals nearby may sit elsewhere. See all services in NW10, W3, W4, W7 and W13.
