Loft Conversion Drawings in West Kensington W14
Fixed-fee, MCIAT-chartered loft conversion drawings for West Kensington (W14) homeowners — London Borough of Hammersmith & Fulham validation and local constraints handled from the start.
West Kensington (W14) is defined by its red-brick Victorian mansion flats — the Gunter family developed much of the district as planned mansion-block and terrace streets, and a large share of the housing is now flats rather than whole houses. That tenure shapes every project: rear, roof and party-wall work here typically touches more than one household.
The Gunter Estate, Barons Court and Sinclair Road conservation areas cover much of the district and protect that planned red-brick character. We establish the conservation boundary, the tenure and the block's shared elements before recommending a route, and draw to the borough's guidance.
Planning in West Kensington (W14): what to know before you apply
W14 sits across the Gunter Estate, Barons Court and Sinclair Road conservation areas, which protect the planned red-brick mansion-flat streets and remove permitted development rights on many of them — and because so much of the stock is flatted, extensions and loft work are assessed against shared roofs, rear elevations and party walls as well as conservation character. London Borough of Hammersmith and Fulham does not publish an Article 4 schedule to the national open-data register, so an empty entry there is not evidence of absence — we confirm the current directions with the council before advising.
Typical West Kensington housing stock

Loft Conversion Drawings for West Kensington (W14) 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 |
