Loft Conversion Drawings in West Ealing W13
Fixed-fee, MCIAT-chartered loft conversion drawings for West Ealing (W13) homeowners — London Borough of Ealing validation and local constraints handled from the start.
In West Ealing (W13) we draw up planning and building-control packages for rear kitchen extensions, loft conversions and refurbishments on the district's Edwardian terraces and villas.
The St Stephen's and Ealing Green conservation areas mean side extensions and roof changes get closer scrutiny, so we check whether your address sits inside the boundary before choosing between permitted development and a full application.
Planning in West Ealing (W13): what to know before you apply
There is no Article 4 direction on the W13 conservation areas, but conservation-area status still removes some permitted-development rights and adds design scrutiny. Homes outside the boundary often keep full rear-extension and loft PD allowances, which we confirm case by case.
Typical West Ealing housing stock
West Ealing is dominated by late-Victorian and Edwardian terraces and semi-detached villas laid out around Northfield Avenue and the St Stephen's streets, many with generous rear gardens suited to extensions.

Loft Conversion Drawings for West Ealing (W13) homes: the package and the process
A loft stands or falls on the section drawing. It has to prove usable head height along the length of the room, a staircase that meets the going and headroom rules without eating the landing below, floor joists sized for a habitable load rather than storage, and a means of escape that Building Control will accept — usually a protected stair, sometimes an escape window.
The same section does the planning work too, showing roof volume, ridge height and how the new form sits against the existing roof. Where the conversion relies on permitted development we set the volume out on the drawing as a calculation, so the position is evidenced rather than asserted.
Roof shape decides which conversion is even possible. A hipped roof has to become a gable before it offers full-width space; a shallow pitch may not deliver head height at any cost; and a terrace with a rear outrigger opens up an L-shaped option a detached house has no use for.
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.
What building regulations apply to a loft conversion?
Loft conversions must meet fire escape, structural and insulation standards — a protected stairway, adequate floor joists and beams, and often a means of escape window. A loft that adds a third storey to a two-storey house triggers stricter fire-separation rules, including fire doors to habitable rooms off the new stairway. We coordinate the structural calculations with the drawings so the build proceeds without delays.
| Loft type | Best for | Usual route | Fee from |
|---|---|---|---|
| Velux / rooflight | Roofs with existing headroom | Permitted development / LDC | £1,100 |
| Dormer | Rear headroom + floor area | Permitted development / LDC | £1,300 |
| Hip-to-gable | Semi and end-of-terrace roofs | Permitted development or planning | £1,600 |
| Mansard | Maximum space, conservation areas | Full planning application | £2,200 |
