Loft conversion builders in Putney
Putney is a family neighbourhood, and many owners prefer to stay put and improve their homes. A loft conversion is the quickest way to add a master suite or a home office. Our loft conversion builders in Putney design the layout, handle structural calculations and approvals, and build to Building Regulations. Several of Wandsworth's conservation areas fall in SW15, so we check the planning position early.
Types of loft conversion in Putney
Across Putney, rear dormers are the usual choice for terraces, hip-to-gable and rear dormer combinations suit semis, and larger villas on Putney Hill can take bigger roof additions. Rooflight-only conversions work for flats and heritage-sensitive roofs.
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
Victorian and Edwardian terraces in West Putney and around Upper Richmond Road take rear dormers well. A Party Wall notice is normally needed because roof structure is shared.
Semi-detached houses
Putney's semis, especially around Lower Common and Putney Hill, often suit hip-to-gable and rear dormer combinations that add a full extra storey.
Detached houses
Large detached villas on Putney Hill and near Putney Heath offer scope for bigger dormers, but conservation area and tree controls often apply.
Is your Putney loft suitable for conversion?
- Roof structure: original cut roofs on Victorian houses convert more easily than modern trussed roofs.
- Head height: around 2.2 metres from floor to ridge is the usual starting point.
- Conservation area: check whether your road falls in Putney Heath, Putney Lower Common, West Putney or Putney Embankment.
- Flats and conversions: many Putney buildings are split into flats, so freeholder consent may be needed.
House extension builders in Putney
Putney's Victorian and Edwardian houses often have long, narrow gardens and small rear kitchens. Our house extension builders in Putney build single-storey rear, side-return and wraparound extensions, taking care of foundations, steelwork, roofing and glazing, and designing carefully where trees or conservation area rules apply.
Putney has steep streets, controlled parking and, near the river, flood zones. We plan deliveries, scaffolding and skips around these, and check Environment Agency flood maps for riverside addresses.
Home renovation and refurbishment in Putney
Many Putney houses have beautiful proportions but dated services and layouts. We carry out whole-house renovations and individual kitchens and bathrooms, coordinating plumbing, electrics, plastering and joinery 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 Putney homes need an experienced local builder
Putney's housing is varied. Victorian and Edwardian terraces fill West Putney and the streets around Upper Richmond Road, larger villas stand on Putney Hill and near Putney Heath, and there are many mansion blocks and riverside flats close to Putney Bridge.
Wandsworth Council manages 46 conservation areas. In Putney, they include Putney Heath, which covers Putney Hill and Tibbet's Ride, Putney Lower Common, West Putney and Putney Embankment. In these areas, roofs, front elevations and trees are more tightly controlled.
Putney also has Putney Heath and common land at its edge, which means protected trees are common. Early tree surveys keep extensions and loft plans realistic.
Putney's streets climb from the river towards the heath, so plots slope, gardens sit at different levels and access can be steep. Those details influence foundations, extension height and where scaffolding can stand. We survey levels and access early so the design and the build plan fit the site.
Do you need planning permission to build in Putney?
Many loft conversions and single-storey rear extensions in Putney can go ahead under permitted development, but conservation areas restrict those rights, and flats have none. Use the table as a guide and confirm your address with Wandsworth 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 Putney Heath or West Putney, or if limits are exceeded |
| Loft conversion in a flat | No, permitted development does not apply to flats | Yes, plus the freeholder's consent |
| Single-storey rear extension | Often yes, up to 3 m (terraced or semi) or 4 m (detached), or 6 m / 8 m through prior approval | Yes, if larger, in a conservation area, or if height and materials rules are exceeded |
| Kitchen or bathroom renovation | Yes, internal work does not need planning | No, though Building Regulations apply and a listed-building check may be needed |
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 Putney home?
Putney's housing varies from compact terraces to large villas. Use this as a starting point, and we will confirm after a site visit.
| Property type | Where you find it | Popular projects |
|---|---|---|
| Victorian and Edwardian terrace | West Putney, Upper Richmond Road | Rear dormer loft, side-return extension, kitchen refit |
| Semi-detached house | Lower Common, West Hill | Hip-to-gable loft, rear extension, full renovation |
| Villa | Putney Hill, Putney Heath | Large dormer, rear extension, whole-house renovation |
| Flat or mansion block | Putney Bridge, Putney Embankment | Internal renovation, kitchen and bathroom refits |
Building in a Putney conservation area
Wandsworth Council has designated 46 conservation areas, and several are in SW15. Always check your address before ordering drawings.
- Putney Heath covers Putney Hill and Tibbet's Ride, with its own appraisal and management strategy.
- Putney Lower Common, West Putney and Putney Embankment are also designated, each with its own appraisal.
- Roof alterations, front dormers, windows and front boundaries are controlled more tightly in these areas.
- Trees in conservation areas are protected, and you must notify the council before cutting or pruning most of them.
We review your address against Wandsworth Council's conservation area maps before design starts, so you know early what is realistic.
What affects the cost of building work in Putney?
No two Putney projects cost the same. The main factors are:
- Project type: a rear dormer, a side-return extension and a villa renovation have very different scopes.
- Flats or houses: flat works involve freeholder approval and shared structure.
- Approvals: planning, heritage statements, tree surveys, structural engineering, Party Wall surveyors and Building Control.
- Access: steep, narrow streets and controlled parking affect deliveries and skips.
- Ground and flood conditions: riverside addresses can need extra groundwork and flood-resilient design.

How to choose a builder in Putney
Searching for a builder in Putney brings up directories, aggregators and many firms. Whoever you choose, check these points first:
- Tree and heritage experience: ask whether they have worked in the Putney Heath or West Putney conservation areas and how they handle tree constraints.
- Ask about sloping sites: Putney's hills affect foundations and access, so ask how they handle levels.
- Check heath and common tree knowledge: protected trees are common near Putney Heath and the Commons.
- Ask about flat conversions: many Putney buildings are split into flats, so freeholder consent matters.
- Confirm conservation area experience: ask about work in Putney Heath, West Putney or Lower Common.
- Insurance: ask to see public liability cover.
- Written estimate: an itemised scope, not a lump sum.

Builders in Putney: frequently asked questions
How much does a builder in Putney cost?
Cost depends on the type, size, structure and finish of the project. A loft conversion, a rear extension and a villa renovation are priced very differently, and conservation area requirements can add cost. Crest Projects gives a written, itemised estimate after a site visit.
Which parts of Putney are in a conservation area?
Wandsworth Council has designated several in Putney, including Putney Heath (which covers Putney Hill), Putney Lower Common, West Putney and Putney Embankment. Check the council's maps for your exact address. We do this before design starts.
Do I need planning permission for a loft conversion in Putney?
For a house, many Putney loft conversions fall under permitted development, within volume limits. For flats, and in conservation areas, planning permission is usually required. A lawful development certificate from Wandsworth Council confirms your position.
Can I extend a large house on Putney Hill?
Often yes, but Putney Hill falls within the Putney Heath conservation area, so design, materials and trees need careful handling. Larger rear and side extensions usually need planning permission. We prepare drawings and applications to suit the council's expectations.
How do trees affect building work in Putney?
Protected trees are common around Putney Heath and the Commons. In conservation areas you must notify the council six weeks before pruning or felling most trees, and root protection areas can limit where foundations can go. We include tree surveys in early design.
Is flood risk a concern for building work in Putney?
Some streets close to the Thames sit in Environment Agency flood zones, which can affect extension levels and basements. Check the flood map for your address. Where it applies, we design with flood resilience in mind.
Do you handle party wall agreements in Putney?
Yes. Most Putney terraces and semis 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 Putney areas do you cover?
We cover Putney Hill, Putney Heath, West Putney, Putney Lower Common, Upper Richmond Road, Putney Bridge and West Hill, plus neighbouring areas such as Fulham, Wimbledon and Richmond.
Do sloping gardens in Putney affect an extension?
They can. Sloping sites change foundation depths, floor levels, steps and how the extension meets the garden, and they can add retaining work. We survey levels early and design so the finished floor, doors and garden connect sensibly.
Can I extend a flat in Putney?
Flats do not have permitted development rights, so most external changes need planning permission and the freeholder's consent. Ground-floor flats sometimes have rear extension potential. Check your lease first. We can review the options with you and your freeholder.
