Hip-to-gable or mansardLarger structural changes to the roof for the maximum usable space.£47,500–£81,000

Your price depends mostly on:

  • Conversion type: rooflight, dormer, hip-to-gable or mansard
  • Floor area, existing head height and roof structure
  • Adding a shower room or en-suite in the roof
  • Staircase layout, fire doors and the level of finishes

Scope of the work

  • Structural calculations and steel beams where needed
  • Dormer, hip-to-gable or rooflight structure as agreed
  • Insulation to walls, roof slope and floor
  • Fire doors, mains-linked smoke alarms and a protected escape route
  • Electrics, heating and plumbing by qualified trades, with certificates
  • Plastering, internal doors and building control sign-off
Rooflight conversionWindows set into the existing roof slope, the simplest option where head height allows.
Rear dormerA box-shaped extension off the rear slope, adding full-height floor space and headroom.
MansardRebuilds the rear slope almost vertically for the most space, common on terraces.
L-shaped dormerTwo dormers joined over a rear wing, giving room for a bedroom and en-suite.

Local housing and a loft conversion

Rows of Victorian red-brick terraces fill much of Manchester, Salford and the mill towns, with stone terraces in the Pennine fringes around Oldham and Saddleworth. South Manchester has Edwardian semis and villas, Wythenshawe was built as a large interwar garden suburb, and city-centre apartments and new estates continue to grow.

Rainfall is high, especially near the Pennines, so brickwork, gutters and roof coverings take a steady soaking and freeze-thaw over winter.

Whatever era your Denton home dates from, we plan a loft conversion around how it is actually built rather than a one-size-fits-all specification.

Planning and building rules in Denton

Each UK nation sets its own consent rules, and Denton is in England. What follows is a plain summary; we check the specifics for your property with the council before pricing anything.

In England, many loft conversions are permitted development: up to 40 m³ of extra roof space on a terraced house and 50 m³ on a semi-detached or detached house, no dormer on the front roof slope facing a road, nothing higher than the existing roof, and similar-looking materials. Conservation areas, listed buildings and flats need planning permission.

Building Regulations approval is always needed for a loft conversion: floor strength, a proper staircase, insulation, fire-protected escape route and smoke alarms. The Party Wall etc. Act 1996 usually applies on attached houses.

Rules change and every property is different, so we check the planning history and constraints for your address before we quote.

What happens after you get in touch?

  1. A visit to your home

    It starts with a survey at the property, free of charge. We check condition, access and services, ask how you want the finished result to look, and answer any questions you have about a loft conversion.

  2. Quote in writing

    We turn the survey notes into a written quote. The price is fixed for the specification we agree, and the document sets out materials, scope and payment stages in plain language.

  3. Plan and prepare

    Preparation matters as much as the build. We agree access, parking and working hours with you, order materials in good time, and confirm any permissions so the job isn't held up once it starts.

  4. The work itself

    The job proceeds in the order set out in the programme, with dust and debris kept under control. Finally we tidy away, inspect the work together and pass the finished project over to you with its paperwork.

What you can expect from us

Permissions checked firstWe check whether planning permission or building control approval is needed for your property, and handle applications and notices where they apply.
Changes agreed in writingIf something needs to change once work is under way, we explain why and confirm the cost or saving in writing before carrying on.
Coverage across the UKWe take on projects in England, Wales, Scotland and Northern Ireland, and plan each one under the rules for the nation it is in.
A proper handoverAt the end we clear the site, show you round the finished work and pass on documents like a building control completion certificate.

Questions about a loft conversion in Denton

Do I need planning permission for a loft conversion?

Whether a loft conversion needs planning permission depends on its size and design, your home's location, whether it is listed or in a conservation area, and which UK nation you live in. In England, many conversions fall under permitted development if the added volume is within 40m³ for terraced houses or 50m³ for other houses and nothing extends beyond the front roof slope. We check what applies before quoting.

How much does a loft conversion cost?

A typical dormer loft conversion on a 3-bed semi costs £28,500–£62,000. A simple rooflight conversion costs less, while hip-to-gable and mansard conversions cost more because they change the roof structure. As a rough guide, allow around £800–£1,700 per square metre of new floor plus fixed costs for the staircase, steels and fees. Adding a shower room is the most common extra. We confirm a fixed price after surveying your loft.

Does the Party Wall Act apply to a loft conversion?

The Party Wall etc. Act 1996 applies in England and Wales only, and loft conversions on terraced and semi-detached houses often fall within it, because steel beams are usually set into the shared wall. You must serve notice on the neighbour before work starts, and they can agree or appoint a surveyor. Scotland and Northern Ireland have no equivalent Act. We tell you during the survey whether notices are likely.

Can I stay at home during the work?

In most cases, yes. Most people can live at home throughout, and we plan the work to keep disruption down by protecting floors, agreeing working hours and keeping access routes clear. Bigger jobs affecting kitchens, bathrooms or heating may mean a short spell with reduced facilities, and we talk this through with you at the survey.

Do you cover Hyde, Dukinfield and Droylsden?

Yes. As well as Denton, we cover Hyde, Dukinfield and Droylsden and the rest of Greater Manchester. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.
