Loft Conversions in Fulham: What You Need to Know
Every loft conversion project in Fulham is designed to respect the Fulham Conservation Area and the character of Victorian terraces, Edwardian cottages, Hurlingham-side villas. Our in-house RIBA Chartered Architects handle Hammersmith & Fulham planning applications, our chartered structural engineers specify any load-bearing work, and our directly-employed trades deliver the build under one fixed-price contract. We coordinate Building Control, Party Wall awards where needed, and all certifications through to handover.
Fulham has conservation area coverage in parts, so some properties will need planning permission for external changes while others may proceed under permitted development. We assess each property individually.
Our loft conversion projects in Fulham are delivered by our in-house team of RIBA architects, structural engineers and specialist tradespeople. Every project is managed under a single fixed-price contract with no hidden costs.
Fulham is classic Victorian family London. In the London Borough of Hammersmith and Fulham, conservation areas protect its best Victorian streets and the riverside around Hurlingham, and it is a family-house area above all — long runs of bay-fronted Victorian terraces and Edwardian cottages. That is exactly why so much of the work here is loft conversions, adding an extra bedroom without leaving a much-loved street.
The planning check is unusually property-specific. Beyond any borough-wide rules, Hammersmith & Fulham has made Article 4 directions restricting permitted-development rights at many individual properties, especially in conservation areas, so two neighbouring houses can sit under different rules. We confirm the exact position for your address, because assuming permitted development in SW6 is a mistake.
The build has its own procedural steps. Where a conversion involves removing part of the roof structure, demolition work may need a Section 80 notice under the Building Act 1984, giving the council six weeks' notice before work starts. On roof form, and excluding VAT, a rooflight scheme starts near £50,000 to £90,000 while a hip-to-gable reaches £65,000 to £120,000, with the bay-fronted terraces on Hurlingham Road and Munster Road ideal candidates.
Loft Conversions in Fulham: Applied to the Local Stock
Fulham sits in the London Borough of Hammersmith and Fulham, with conservation areas protecting its best Victorian streets and the riverside around Hurlingham. Beyond the borough-wide basement direction, Hammersmith & Fulham has made Article 4 directions restricting permitted development rights at many individual properties — especially in conservation areas, to protect against unsuitable alterations — with directions covering Fulham streets and areas including Central Fulham (1)-(2), Fulham Park Gardens, Hurlingham, Studdridge Street (1)-(2), Walham Grove (1)-(2), Mimosa Street, Imperial Square and Fabian Road. Hammersmith and Fulham scrutinises external change in its conservation areas and applies Article 4 controls.
In Hammersmith & Fulham conservation areas, significant demolition needs planning permission (conservation area consent was replaced from 1 October 2013), a heritage statement is usually required, and demolishing a building in a conservation area without consent remains a criminal offence.

What a Loft Conversion Involves
Converting a loft turns dead roof space into a proper storey — usually a bedroom suite, office or studio — with the staircase, steelwork, insulation and fire strategy resolved together rather than improvised on site. Steels are engineered before a rafter is cut, the staircase position is fixed early so the floor below keeps its shape, and the whole build runs under one fixed-price contract. The right approach depends on your roof, and we design and build all of the main forms.
- Rear dormer — a flat-roofed extension off the back slope giving vertical walls and the most usable floor area on a terrace
- Mansard — the rear slope rebuilt almost vertical for maximum volume; the premium option on period streets, always via planning
- Hip-to-gable — the sloping side of a hipped roof squared off into a gable, transforming semis and end-of-terrace houses
- Velux / rooflight — windows set into the existing slope, the lightest-touch route where ridge height already allows
- L-shaped dormer — twin dormers over the main roof and the rear addition of a period terrace, often gaining two rooms
Whichever form suits your roof, the scope runs from steel and floor structure through staircase, en-suite plumbing, insulation, fire doors and detection to fitted eaves storage and final decoration.
How We Run Your Project
Six stages, engineered on paper before the roof is touched.
- Loft survey — we check ridge height, roof structure and party wall position, and confirm what your roof can genuinely accommodate.
- Design & engineering — our architects plan the rooms and staircase while the steel and floor structure are calculated alongside.
- Consents — permitted development confirmation, a planning application where one is needed, party wall notices and the building control submission.
- Fixed-price contract — a complete specification agreed before scaffolding goes up.
- Structure to fit-out — steels in, dormer or mansard built and made weathertight from outside, then staircase, bathroom, insulation and decoration inside.
- Sign-off & handover — snagging, the building control completion certificate and your warranty pack before we leave.

Many dormer and hip-to-gable conversions fall within permitted development, subject to volume allowances of 40 cubic metres on terraced houses and 50 on semis and detached homes — though conservation areas restrict this and flats have no loft PD rights at all. Where new steels bear on a wall shared with a neighbour, the Party Wall etc. Act 1996 requires two months’ notice before work begins, and Building Regulations govern the structure, staircase, insulation and fire safety of every conversion. Our planning guide library explains what applies in your borough.
Why Hampstead Renovations
A loft conversion is a structural project wearing a bedroom’s clothes, and we staff it accordingly. Layouts come from our in-house RIBA Chartered Architects, the steelwork is designed by our own structural engineers, and party wall support comes through RICS surveying at our sister company, Hampstead Chartered Surveyors. Delivery is by our long-standing build teams on a fixed-price JCT contract, insured to £10M for public liability, with a 12-month defects period and a 10-year workmanship warranty. Enquire before 2pm on a weekday and we will call you back the same day.
Loft Conversions in Fulham: Questions
Do loft conversions in Fulham need planning permission?
Often, and you cannot assume otherwise. Hammersmith & Fulham scrutinises external change in its conservation areas and applies Article 4 controls, and it has made Article 4 directions at many individual properties, especially in conservation areas. Because two neighbouring houses can sit under different rules, we confirm the exact position for your address first.
Which Fulham houses suit a loft conversion?
The bay-fronted Victorian terraces, above all. Generous family houses on Hurlingham Road and Munster Road are ideal for whole-house refurbishment, lofts and rear extensions, and their roofs take a conversion comfortably. On these streets a loft is the classic way to add a bedroom without moving.
What does a loft conversion cost in Fulham, and what forms are there?
Excluding VAT and on a London-wide basis, a dormer runs £60,000 to £100,000, a mansard £65,000 to £110,000, a hip-to-gable £65,000 to £120,000 and a Velux or skylight scheme £50,000 to £90,000. On a bay-fronted terrace a rear dormer or hip-to-gable usually gives the most usable room, subject to the conservation area.
Is a loft the best way to add a bedroom to a Fulham house?
For most family houses here, yes. These are family homes, and the work reflects it: loft conversions for an extra bedroom, rear and side-return extensions to open kitchens to gardens, and whole-house refurbishment. A loft adds a room and often an en-suite while leaving the footprint and garden untouched.
Does a Fulham loft need a demolition notice?
It can. Where the work involves removing part of the roof structure, demolition in Hammersmith & Fulham may require a Section 80 notice under the Building Act 1984, giving the council six weeks' notice before work begins, and significant demolition in a conservation area needs planning permission with a heritage statement. We handle those notices as part of the project.
