Covering Formby
Our coverage around Formby (L37) also includes Maghull (6 miles to the south-east) and Southport.
Homes in the North West
Terraced housing is a defining feature of many North West towns, which brings party walls and narrow access into most projects, with more space to extend on suburban semis.
What does a loft conversion involve?
We start with the head height. You need roughly 2.2 m or more from the top of the ceiling joists to the underside of the ridge for a conversion to work without raising the roof. From there we design the staircase position, the type of conversion and the en-suite, and manage the whole build including fire safety and building control.
- Planning or lawful development certificate
- Dormer or rooflights, insulation and plasterboard
- En-suite, electrics, heating and fire safety upgrades
What will a loft conversion cost?
Indicative costs for loft conversions. London and the South East usually sit towards the top of each range.

| Rooflight conversion | £30,000 to £45,000 |
| Dormer conversion | £50,000 to £90,000 |

Planning and building rules in Formby
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.
In England many loft conversions are permitted development: the extra roof volume must stay within 40 m³ on a terraced house or 50 m³ on a semi or detached house, nothing can sit higher than the existing ridge, no dormer can face a road on the main elevation, and side windows must be obscure-glazed and non-opening below 1.7 m. Houses in conservation areas, National Parks and National Landscapes cannot use these roof-extension rights, so dormers there need planning permission (a rooflight-only conversion can still be permitted development), and flats always need permission.
What can change the price or programme?
- The new staircase usually takes space from the landing or a bedroom below.
- Fire safety rules can mean new fire doors on the floors below.
How does the project run?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- 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.

Is my loft suitable for conversion?
If there is about 2.2 m or more from the top of the ceiling joists to the underside of the ridge, it usually is. We check this at the free site visit.

In England many are permitted development, within 40 m³ of extra volume on a terrace or 50 m³ on a semi or detached house. Conservation areas and flats need permission.
Who deals with the council for a project in Formby?
We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
