Covering Brighouse
Brighouse sits 12 miles south-west of Leeds, with Halifax 3 miles to the west and Cleckheaton 3 miles to the north-east.
Homes in Yorkshire and the Humber
Yorkshire has a strong mix of stone terraces, red-brick semis and modern estates, plus conservation areas in many historic towns and villages.
What goes into an upward extension?
The first question is whether the existing walls and foundations can carry the extra load, so we start with a structural survey. Then we design either a full first floor or a raised roof with dormers, handle planning or prior approval, and build the new storey while protecting the floor below.
- Structural survey of walls and foundations
- Design and planning or prior approval application
- Roof removal and temporary weather protection
What will an upward extension cost?
Indicative costs for bungalow and upward extensions. London and the South East usually sit towards the top of each range.
| Bungalow and upward extensions | Guide price incl. VAT |
|---|---|
| Chalet conversion with dormers (total) | £45,000 to £85,000 |
| New first floor, standard specification | £2,200 to £2,800 per m² |
| New first floor, good specification | £2,800 to £3,300 per m² |
| New first floor, high specification | £3,300 to £3,800 per m² |
What approvals does an upward extension need in England?
Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.
In England, Class AA permitted development allows an extra storey on many detached and semi-detached houses built between July 1948 and October 2018, subject to a prior approval application covering design, neighbours’ amenity and other matters. Houses in conservation areas and other protected land need full planning permission, as do most chalet conversions with front dormers.
What should Brighouse homeowners check first?
- Some bungalow foundations need strengthening before a storey can be added.
- The house is exposed while the roof is off, so the sequence is planned tightly.
What are the steps?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
What people ask before starting
Is an upward extension permitted development?
In England, Class AA allows it on many post-1948 houses through a prior approval application. Elsewhere planning permission is needed.
Do we need to move out?
Often for part of the job, while the roof is off and the new floor is formed. We plan this with you.
Who deals with the council for a project in Brighouse?
We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
