Greenford (UB6) is classic outer-west-London Metro-land: broad avenues of interwar semis with deep gardens, ideal for rear and wraparound kitchen extensions, loft conversions with rear dormers, and garage-to-room conversions. Most householder projects here fall squarely within permitted development or a straightforward Ealing Council householder application.

The one sensitivity is the Canalside conservation area on the neighbourhood's north-west flank near the Grand Union, where materials and rear massing get closer scrutiny. We prepare drawings that hold the interwar building line and gap-to-boundary rhythm Ealing's officers expect, and flag any canal-edge or former-industrial plot early so ground and drainage issues are designed out.

Planning in Greenford (UB6): what to know before you apply

No published householder Article 4 direction in Greenford, so most extensions and lofts run under permitted development or a standard Ealing householder application. Properties bordering the Canalside conservation area lose some permitted-development rights, and rear/side extension depths are assessed against the neighbouring semis' building line.

Typical Greenford housing stock

Greenford is dominated by 1920s-30s bay-fronted semis and short terraces laid out along wide suburban avenues, many with generous rear gardens and original hipped roofs. Nearer the Grand Union Canal and the old Rockware/Lyon works, plots give way to former industrial land and later flat-roofed infill.

Loft Conversion Drawings for Greenford (UB6) homes: the package and the process

Every loft conversion drawings we prepare for an Greenford property is drawn to London Borough of Ealing’s validation standards and tuned to the UB6 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.

A loft conversion is one of the most cost-effective ways to add a bedroom in London — but the right drawings depend on your roof type, your borough's rules and whether the work is permitted development or needs planning permission. DrawingsDirect draws every loft type and checks your permitted development eligibility before you commit to an application. Getting the route right at the drawing stage is what protects the whole build: a loft designed as permitted development but actually needing planning permission stalls on site, while one over-specified for a full application pays for consent it never needed.

Do I need planning permission for a loft conversion in London?

Many loft conversions are permitted development, but volume limits (40m³ for terraced homes, 50m³ for detached and semi-detached), materials and the presence of a conservation area or Article 4 direction can change that. We assess your roof and borough and recommend the fastest lawful route — often a Lawful Development Certificate rather than a full planning application. A certificate is worth having even when the work is clearly permitted: it gives your buyer's solicitor and your building-control surveyor documentary proof the loft is lawful, which matters when you sell.

Which loft conversion type suits your roof?

The best conversion depends on your roof shape and the headroom it offers.

Dormer

A box dormer adds headroom and floor area at the rear and is the most common London loft — frequently permitted development.

Mansard

A mansard rebuilds the rear (or front and rear) roof slope for maximum space, common in conservation areas but usually needing planning permission.

Hip-to-gable

Extends a hipped roof to a vertical gable, ideal for semi-detached and end-of-terrace homes.

Velux / rooflight

The simplest option — rooflights within the existing roofline, almost always permitted development.

FAQ

Loft Conversion Drawings in Greenford UB6 — FAQs

How much do loft conversion drawings cost in London?+
Drawing packages typically start around £1,100 for a permitted development loft and rise for mansards or full planning applications with structural calculations. We quote a fixed fee upfront.
Will my loft need a fire escape window?+
Most loft conversions require a means of escape and a protected stairway under building regulations. We design these in from the start.
Is a dormer loft permitted development?+
Often yes, within the volume limits and outside conservation areas — but we always check your specific property and borough first, free.
Can I convert my loft if I live in a conservation area?+
Usually yes, but conservation areas and Article 4 directions often remove permitted development for rear dormers, so the work needs a full planning application and a roof-form the council will accept — commonly a mansard or discreet rear dormer. We check your borough's designation before recommending a route.
Do you provide the structural calculations for the steels?+
Yes. Our full package includes structural drawings and calculations for the floor beams and any ridge or purlin steels, coordinated in-house so your builder can price and build without waiting on a separate engineer.
Do I need planning permission for a rear extension in Ealing?+
Many Ealing semis and terraces keep permitted development rights for a single-storey rear extension, so a full application isn't always needed. But the borough-wide Article 4 direction on HMO conversions, and conservation areas such as Bedford Park and Pitshanger, remove or restrict those rights in places. We check your address against the designations first and, where it qualifies, confirm permitted development with a Lawful Development Certificate.
What extra control applies in Bedford Park?+
Bedford Park is one of West London's most tightly controlled conservation areas, with detailed control over materials, rooflines, windows and front elevations. A standard permitted-development dormer or cladding change usually won't apply; instead we design to the area's Arts-and-Crafts character and prepare a full householder application with the elevations and materials the council expects — the reliable route to approval there.
How long does Ealing Council take to decide a householder application?+
Ealing determines most householder applications within the statutory eight-week period once they are validated. The commonest cause of delay is a validation query over missing or inconsistent drawings, so we prepare Ealing submissions to the council's validation checklist — correctly scaled existing and proposed plans, elevations and a location plan — to avoid that back-and-forth.
Can you help with a loft conversion on a 1930s Ealing semi?+
Yes. Ealing's Metro-land semis in Perivale, Greenford and Northolt suit hip-to-gable and dormer loft conversions, which frequently qualify as permitted development on semi-detached homes within the volume limits. We confirm eligibility against those limits and any Article 4 or conservation constraint, then produce the planning and building-regulations drawings.
How much do planning drawings cost in Ealing?+
We work to a fixed fee agreed before we start, typically around 30% below an architect's charge for the same council-accepted drawings, with free redraws until Ealing grants approval. The exact figure depends on the project — a single-storey rear extension differs from a double-storey or a loft — so we quote once we understand your scheme rather than on an open-ended hourly basis.
