Loft conversion builders in Fulham
Fulham is full of Victorian terraces with narrow footprints, so building up is often the most practical way to add a bedroom. A loft conversion in SW6 typically gives a main bedroom with an en-suite and keeps the garden intact. Our loft conversion builders in Fulham design the layout, handle structural calculations and approvals, and build to Building Regulations for stairs, fire safety and insulation. Many Fulham homes were converted into flats, so we also help with freeholder consent.
Types of loft conversion in Fulham
Fulham's long rows of Victorian terraces make the rear dormer the standard answer, often combined with a rear outrigger extension below. Rooflight-only conversions suit flats where the roof shape cannot change, and mansards are uncommon and tightly controlled.
Rooflight (Velux) conversions
Roof windows added without changing the roof shape.
Rear dormer loft conversions
Full-height space at the back of the roof.
Hip-to-gable loft conversions
Straightens a sloping side roof for a larger room.
Mansard loft conversions
Steep-sided, flat-roofed. Needs planning permission.
Loft conversions by property type
Terraced houses
Long runs of Victorian terraces in Parsons Green, Munster Village and Walham Green take rear dormers well. Because roof structure is shared, a Party Wall notice is normally needed.
Semi-detached houses
Larger Edwardian semis towards Hurlingham and Bishop's Park may suit hip-to-gable and rear dormer combinations that add a full extra floor.
Detached houses
Detached houses are rare in SW6, but where they exist they allow bigger dormers, subject to the council's conservation area rules.
Is your Fulham loft suitable for conversion?
- Houses or flats: flats need the freeholder's consent and often a lease variation, so check who owns the roof space first.
- Head height: around 2.2 metres from floor to ridge is the usual starting point.
- Existing extensions: a rear outrigger or previous dormer can use up permitted development allowance.
- Roof structure: original cut roofs convert more easily than modern trussed roofs.
House extension builders in Fulham
Fulham's Victorian terraces were built with narrow side passages and small back rooms. A side-return or wraparound extension is the classic answer, making a bright kitchen-diner that opens onto the garden. Our house extension builders in Fulham build single-storey rear, side-return and wraparound extensions, taking care of foundations, steelwork, roofing and glazing.
On Fulham's tight terraced streets, planning how to bring materials in and take rubble out is half the job. We plan deliveries, skips and scaffolding in advance, and keep neighbours informed throughout.
Home renovation and refurbishment in Fulham
Many SW6 homes are period houses or flats that have not been fully updated in decades. We carry out whole-house renovations and individual kitchens and bathrooms, coordinating plumbers, electricians, plasterers and joiners under one team.
- Full house renovation: strip-out, structural changes, services and finishes managed as one project. House renovation

- Bathroom renovation: waterproofing, tiling, plumbing and fitting. Bathroom renovation
Why Fulham homes need an experienced local builder
Fulham's character comes from its Victorian terraces, built in long, uniform rows across Parsons Green, Munster Village, Walham Green and Sands End, mixed with larger Edwardian houses near Bishop's Park and Hurlingham and a large number of flat conversions and mansion blocks.
The London Borough of Hammersmith and Fulham has 44 conservation areas covering about half of the borough, including Fulham Park Gardens. In those areas, changes visible from the street, such as roofs, windows and front boundaries, are controlled more tightly.
Parts of SW6 close to the Thames also sit in flood zones, which affects basements and ground-floor levels. We check this early and design to suit.
Many Fulham terraces share the same plan: a rear outrigger, a small garden and a narrow side passage. That repeated layout means neighbours on both sides have often extended already, which can help with planning but can also use up allowances. We check what has been built nearby before we design.
Do you need planning permission to build in Fulham?
Many loft conversions and rear extensions on Fulham houses fall under permitted development, but flats do not have those rights, and conservation areas restrict them further. Use the table as a guide and confirm your address with the council.
| Project | Permitted development | Planning permission needed |
|---|---|---|
| Loft conversion (rear dormer) on a house | Often yes, within volume limits (40 m³ terraced, 50 m³ semi-detached or detached) | Yes, in conservation areas such as Fulham Park Gardens, or if limits are exceeded |
| Loft conversion in a flat | No, permitted development does not apply to flats | Yes, plus the freeholder's consent |
| Side-return extension | Sometimes, if single storey and within width and height limits | Often yes, especially in conservation areas or where it wraps around the rear |
| Basement or lower-ground works | No, excavation needs full planning permission | Yes, with structural and flood risk assessment |
General guidance only. Rules depend on your property, location and any Article 4 direction. We check this for you before design starts.
Which project suits your Fulham home?
Fulham's housing mix shapes the projects that work best. Use this as a starting point, and we will confirm after a site visit.
| Property type | Where you find it | Popular projects |
|---|---|---|
| Victorian terrace | Parsons Green, Munster Village, Walham Green, Sands End | Rear dormer loft, side-return extension, kitchen refit |
| Edwardian semi-detached house | Hurlingham, Bishop's Park | Hip-to-gable loft, rear extension, full renovation |
| Flat or maisonette | Fulham Broadway, North End Road, Fulham Park Gardens | Internal renovation, kitchen and bathroom refits, loft with freeholder consent |
| Riverside house | Sands End, Bishop's Park | Flood-aware renovation, rear extension |
Building in a Fulham conservation area
Hammersmith and Fulham Council has designated 44 conservation areas covering about half the borough. Always check your address before ordering drawings.
- Fulham Park Gardens is one of the designated conservation areas, with its own character profile.
- Roof alterations, front dormers and changes to front elevations normally need planning permission in a conservation area.
- Materials, windows and brickwork are expected to match the original building.
- Listed buildings need Listed Building Consent for most external and internal changes.
We review your address against the council's conservation area maps before design starts, so you know early what is realistic.
What affects the cost of building work in Fulham?
No two Fulham projects cost the same. The main factors are:
- Project type: a rear dormer, a wraparound extension and a whole-house renovation have very different scopes.
- Flats or houses: flat works involve freeholder approval, noise restrictions and shared structure.
- Approvals: planning, structural engineering, Party Wall surveyors and Building Control.
- Access: controlled parking zones and tight terraces mean parking suspensions and skip licences.
- Flood and ground conditions: riverside streets can need extra groundwork and flood-resilient design.

How to choose a builder in Fulham
Searching for a builder in Fulham brings up directories, aggregators and many firms. Whoever you choose, check these points first:
- Terrace and flat experience: ask how they manage access on tight terraced streets and shared structures in converted flats.
- Ask about outrigger extensions: most Fulham terraces have one, so a good builder should know how to extend them.
- Check flat experience: many SW6 homes are flats, so ask how freeholder consent is handled.
- Ask about narrow-street logistics: tight terraces make access and skips difficult, so ask for their plan.
- See recent terrace work: ask for photos and references from similar Victorian houses.
- Insurance: ask to see public liability cover.
- Written estimate: an itemised scope, not a lump sum.

Builders in Fulham: frequently asked questions
How much does a builder in Fulham cost?
Cost depends on the type, size, structure and finish of the project. A loft conversion, a side-return extension and a full renovation are priced very differently, and flats or period houses can add structural or access costs. Crest Projects gives a written, itemised estimate after a site visit.
Can I convert the loft in a Fulham flat?
Sometimes. Permitted development rights do not apply to flats, so you need planning permission and also the freeholder's consent, often with a lease variation. Whether it is possible depends on who owns the roof space and the structure. We can review your position.
Do I need planning permission for a loft conversion in Fulham?
For a house, many loft conversions fall under permitted development, within volume limits. For flats, and in conservation areas such as Fulham Park Gardens, planning permission is usually required. A lawful development certificate from the council confirms your position.
What is the best extension for a Victorian terrace in Fulham?
A side-return extension, often combined with a rear extension, is the most popular option because it widens a narrow kitchen and brings in light. A wraparound gives the most space. The best choice depends on plot width, neighbours' extensions and the planning position.
Is flood risk a concern for building work in Fulham?
Parts of SW6 close to the Thames sit in Environment Agency flood zones, which can affect basements and ground-floor levels. Check the flood map for your address. Where it applies, we design with flood resilience in mind and talk through the options with you.
Can I add a basement to my Fulham house?
A basement needs full planning permission and a structural and flood-risk assessment. The council examines basements closely, especially in conservation areas, and neighbours must be notified under the Party Wall Act. Feasibility depends on soil, groundwater and your street. We can advise early on whether it is realistic.
Do you handle party wall agreements in Fulham?
Yes. Most Fulham terraces share a wall, so loft conversions, side returns and deeper foundations usually need a Party Wall Act 1996 notice. We guide you through serving notices and agreeing a schedule of condition.
Which Fulham areas do you cover?
We cover Parsons Green, Munster Village, Hurlingham, Sands End, Walham Green, Fulham Broadway, North End Road and Bishop's Park, plus neighbouring areas such as Hammersmith, Putney and Kensington.
What is an outrigger and can it be extended?
An outrigger is the narrower rear wing found on many Fulham Victorian terraces. It can usually be extended sideways or backwards, subject to depth limits and neighbours. A side-return extension fills the gap beside it. We check planning limits, neighbouring extensions and structure before recommending a layout.
Can I extend a Fulham terrace if my neighbour already has?
Often yes, and neighbouring extensions can help show what the council has accepted. They may also use up some of your permitted development allowance if the same owner extended. We check the planning history of nearby properties before we design.
