Loft conversions in Basildon

Planning loft conversions in Basildon? We design and build them for houses across Essex, and we fix the price for the agreed specification in writing before any building work starts.

Covering Basildon

Basildon is about 12 miles south of Chelmsford. We also cover Pitsea (2 miles to the east), Stanford-le-Hope and Wickford.

Homes in the East of England

Housing in the East of England ranges from post-war estates and modern developments to timber-framed and period homes in historic towns, so permitted development checks and conservation controls both feature regularly.

What does a loft conversion involve?

A loft conversion turns an unused roof space into habitable rooms, usually a bedroom with an en-suite, by strengthening the floor, adding a staircase, insulating the roof and putting in windows. The type you need depends on the roof: rooflight, dormer, hip-to-gable or mansard.

  • Design drawings and structural calculations
  • Planning or lawful development certificate
  • New floor joists, steels and staircase

How much should I budget for a loft conversion?

Typical ranges for loft conversions. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.

Loft conversionsGuide price incl. VAT
Rooflight conversion£30,000 to £45,000
Dormer conversion£50,000 to £90,000
Hip-to-gable with dormer£60,000 to £95,000
Mansard conversion£65,000 to £110,000

What approvals does a loft conversion need in England?

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 should I think about before starting?

  • Fire safety rules can mean new fire doors on the floors below.
  • Party wall notices are often needed for steels bearing on a shared wall.

How does the project run?

  1. Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
  2. Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
  3. Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
  4. Construction and completion. One site lead co-ordinates every trade through to the building control certificate.

Loft conversions: common questions

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.

Can we live at home during a loft conversion?

Yes. Most of the work is done from scaffolding until the staircase goes in near the end.

Who deals with the council for a project in Basildon?

We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
