What types of loft conversion do we build?

The right loft conversion depends on your roof shape and how much head height you have. We build:

  • Rear dormer – a box-shaped extension on the rear roof slope that adds full-height floor space
  • Hip-to-gable – the sloping side of the roof is built up into a vertical gable, common on 1930s semis
  • Rooflight conversion – windows set into the existing roof slope, with no change to the roof shape

Carpentry is in our name, so the structural timber work at the heart of a loft conversion, from new floor joists to the roof structure, is done by our own team.

Do loft conversions in Hemel Hempstead need planning permission?

Often not. Many loft conversions are permitted development, within a volume allowance of 40 cubic metres for terraced houses and 50 cubic metres for semi-detached and detached houses. Dormers facing the road, mansard roofs and homes in conservation areas such as Hemel's Old Town and Boxmoor usually need a planning application to Dacorum Borough Council.

Building Regulations approval is always needed. It covers the structure, a protected escape route with fire doors and interlinked smoke alarms, the stairs and insulation. Our loft conversion guide explains the rules in detail.

How does a loft conversion project work?

  1. Survey – we check head height, roof structure and where the new stairs will land.
  2. Drawings and approvals – drawings, structural calculations, Building Regulations approval and any party wall notices.
  3. Structure – new floor joists, steelwork where needed, and the dormer or gable built and roofed.
  4. First fix – stud walls, stairs, windows and services routed before plastering.
  5. Finishing – plastering, doors, skirting, decorating and building control sign-off.

Loft conversions in Hemel Hempstead: frequently asked questions

Do I need planning permission for a loft conversion in Hemel Hempstead?

Often not. Many loft conversions are permitted development within 40 cubic metres for a terraced house or 50 cubic metres for other houses. Front dormers, mansards and homes in conservation areas need a planning application to Dacorum Borough Council.

Is my loft suitable for conversion?

A common rule of thumb is about 2.2 metres of head height from the top of the ceiling joists to the underside of the ridge. We check head height, roof structure and stair position when we survey.

Do I need fire doors for a loft conversion?

Usually, yes. Building Regulations require a protected escape route from the new room, which in a typical two-storey house means fire doors onto the stairway and interlinked smoke alarms.

Will I need a party wall agreement?

In a semi or terrace, usually yes, because steel beams often bear on the shared wall. Notice must be served at least 2 months before that work starts.

How much does a loft conversion cost?

It depends on the type of conversion, the size, the roof structure, stairs and finishes. We give a free, itemised written quote after a survey.
