Loft conversion builders in Hampton
Hampton is a quiet, family-focused part of south-west London, close to Bushy Park and Hampton Court. Many owners prefer to extend rather than move, and a loft conversion is often the most economical way to gain a bedroom. Our loft conversion builders in Hampton design the layout, handle the structural calculations and approvals, and build to Building Regulations. We check conservation area rules at the start, because Hampton Village, Hampton Hill High Street and Hampton Court all have designated areas.
Types of loft conversion in Hampton
In Hampton, rear dormers suit the Victorian cottages and Edwardian terraces, while hip-to-gable and rear dormer combinations suit the many interwar semis. Rooflight-only conversions can work for lofts with good height, and mansards are very uncommon in this part of the borough.
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 Hampton Hill and Hampton Village suit rear dormers. A Party Wall notice is normally needed, and roof changes near conservation areas need extra care.
Semi-detached houses
Interwar and Edwardian semis across Hampton, Fulwell and Hanworth are good candidates for a hip-to-gable and rear dormer combination that adds a full storey.
Detached houses
Detached houses around Hampton Court and Hampton Wick have scope for larger dormers, though conservation area and tree rules can apply.
Is your Hampton loft suitable for conversion?
- Roof structure: original cut roofs 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 street is in Hampton Village, Hampton Hill High Street or the Hampton Court areas.
- Existing work: earlier dormers or extensions may already use some of your permitted development allowance.
House extension builders in Hampton
Hampton's plots are often a good size, which gives plenty of scope for rear and side extensions. Our house extension builders in Hampton build single-storey rear, side-return and wraparound extensions, taking care of foundations, steelwork, roofing and glazing, with careful design where a house sits in a conservation area.
Hampton sits close to the Thames, so we check Environment Agency flood maps and ground conditions at the start. We also plan deliveries and skips around its residential roads and the busy approach to Hampton Court.

Hampton has many family homes that are ready for rewiring, replumbing and a new layout. We carry out whole-house renovations and individual kitchens and bathrooms, coordinating all trades under one team. We have recently completed a renovation in Hampton, so we know the area's housing well.

Why Hampton homes need an experienced local builder
Hampton's housing is a mixture of Victorian cottages and terraces around Hampton Village and Hampton Hill, Edwardian houses, and interwar semis spreading towards Fulwell and Hanworth. Closer to the river, Hampton Court and Hampton Wick have older and often larger properties.
Richmond Council has designated several conservation areas here. Hampton Village (Conservation Area 12) was designated in 1969 and extended in 1982, 1991 and 2023. Hampton Hill High Street (Conservation Area 38) dates from 1982, and Hampton Court Green and Hampton Court Park are separate designated areas.
Because Hampton is in the London Borough of Richmond upon Thames, trees, heritage and views matter. We bring experience of how the council assesses applications, which keeps your project on track.
Hampton's housing changes quickly from the compact Victorian cottages around the village to the more spacious interwar streets further out. We have recently completed a renovation in Hampton, which gave us a close look at how these older homes behave once the plaster comes off, and we apply that experience to new projects here.
Do you need planning permission to build in Hampton?
Many loft conversions and single-storey rear extensions in Hampton can go ahead under permitted development, but conservation areas restrict those rights. Use the table as a guide and confirm your address with Richmond Council.
| Project | Permitted development | Planning permission needed |
|---|---|---|
| Loft conversion (rear dormer) | Often yes, within volume limits (40 m³ terraced, 50 m³ semi-detached or detached) | Yes, in conservation areas such as Hampton Village, or if limits are exceeded |
| 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 |
| 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 |
| 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 Hampton home?
Hampton's housing mix shapes which projects 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 cottage and terrace | Hampton Village, Hampton Hill | Rear dormer loft, side-return extension, kitchen refit |
| Edwardian house | Hampton Hill, Hampton Village fringe | Loft conversion, rear extension, whole-house renovation |
| Interwar semi-detached house | Fulwell, Hanworth, Hampton | Hip-to-gable loft, rear extension, kitchen and bathroom refits |
| Period and riverside property | Hampton Court, Hampton Wick | Sensitive renovation, flood-aware extension |
Building in a Hampton conservation area
Richmond Council has designated several conservation areas in and around Hampton. Always check your address before ordering drawings.
- Hampton Village (Conservation Area 12) was designated in 1969 and extended in 1982, 1991 and 2023, with an appraisal adopted in November 2023.
- Hampton Hill High Street (Conservation Area 38) was designated in 1982 and has its own appraisal.
- Hampton Court Green and Hampton Court Park are separate conservation areas near the palace.
- Trees in conservation areas are protected, and you must notify the council before cutting or pruning most of them.
We review your address against Richmond Council's conservation area maps before design starts, so you know early what is realistic.
What affects the cost of building work in Hampton?
No two Hampton projects cost the same. The main factors are:
- Project type: a rear dormer, a side-return extension and a whole-house renovation have very different scopes.
- Age of the house: Victorian cottages often need more structural work than interwar semis.
- Approvals: planning, structural engineering, Party Wall surveyors and Building Control.
- Ground and flood conditions: closeness to the Thames can mean extra groundwork and flood-resilient design.
- Finish level: glazing, kitchens, bathrooms and flooring often drive the budget.

How to choose a builder in Hampton
Searching for a builder in Hampton brings up directories, aggregators and many firms. Whoever you choose, check these points first:
- Local project examples: ask to see recent work in Hampton or neighbouring areas such as Teddington, Twickenham and Hampton Hill.
- Ask about Hampton projects: we have completed a renovation here and can discuss it with you.
- Check conservation area knowledge: Hampton Village, Hampton Hill High Street and Hampton Court have designated areas.
- Ask about riverside ground conditions: properties near the Thames may need extra groundwork and flood awareness.
- Confirm tree handling: mature trees near Bushy Park and the Court can affect design.
- Insurance: ask to see public liability cover.
- Written estimate: an itemised scope, not a lump sum.

Builders in Hampton: frequently asked questions
How much does a builder in Hampton cost?
Hampton projects range from a rear dormer on a Victorian cottage to a full renovation of an interwar semi, and the price depends on structure, finish and conservation area requirements. We give a written, itemised estimate after a site visit, and our online cost calculator gives a first figure.
Which parts of Hampton are in a conservation area?
Richmond Council has designated several, including Hampton Village, Hampton Hill High Street, Hampton Court Green and Hampton Court Park. 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 Hampton?
In Hampton, a rear dormer on a terrace or semi is often permitted development within volume limits. The exceptions are homes in Hampton Village, Hampton Hill High Street or the Hampton Court areas, front roof slopes, and homes whose earlier extensions have used up the allowance. A lawful development certificate from Richmond Council settles the question.
Have Crest Projects worked in Hampton?
Yes. We have recently completed a renovation in Hampton, and we regularly work across neighbouring Teddington, Twickenham and Richmond. That local experience helps with planning, access and neighbours.
What is the best extension for an interwar semi in Hampton?
A rear extension, often with a hip-to-gable and rear dormer loft above, is the most common combination. It adds a larger kitchen-diner and an extra bedroom and bathroom. The best choice depends on plot size, neighbours' extensions and the planning position.
Is flood risk a concern for building work in Hampton?
Parts of Hampton near 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 Hampton?
Yes. Hampton's Victorian cottages and terraces often share walls, and even semis share a party wall through the roof space, so loft conversions and extensions near a boundary can need a Party Wall Act 1996 notice. We prepare the notices and the schedule of condition and keep neighbours informed through the build.
Which Hampton areas do you cover?
We cover Hampton Village, Hampton Hill, Hampton Court, Hampton Wick, Fulwell, Hanworth and Hampton Nursery Lands, plus neighbouring areas such as Teddington, Twickenham and Richmond.
Is Hampton Court a conservation area?
Hampton Court Green and Hampton Court Park are separate designated conservation areas, alongside Hampton Village and Hampton Hill High Street. Houses within or next to them face tighter rules on roofs, windows and extensions. We check designations for your address before design starts.
Can you extend a Victorian cottage in Hampton Village?
Often, yes, usually with a sensitive rear extension. Hampton Village is a conservation area, so materials, proportions and any roof changes need care. We design to suit the cottage's character and prepare drawings that are likely to satisfy Richmond Council.
