Loft conversion types
Find the right conversion for your roof
The best choice depends on your roof shape, your head height and your budget. These are the types we are asked about most.
Dormer Loft Conversion
A box shaped extension that adds head height and floor space. A popular choice for terraced and semi detached homes.

Built across the back roof slope, out of sight from the street, with room for a bedroom and en suite.

A steep, almost vertical rear slope that gives generous headroom and floor space.

We look at the details that decide the price
A loft conversion is a structural job. Getting the first checks right avoids surprises later.
- Head height and floor area. We measure what you have now to see which conversions are possible.
- Roof shape and structure. The roof type decides whether a dormer, hip to gable or mansard will suit.
- The planning route. Many loft conversions use permitted development. Conservation areas and flats follow different rules.
- Building regulations. Every loft conversion needs approval for the structure, stairs, fire safety and insulation.

Common questions
Questions homeowners ask
Do I need planning permission for a loft conversion?
Many loft conversions can be built under permitted development, so they do not need a full planning application. Limits apply. For example, a terraced house can add up to 40 cubic metres of roof space and a semi detached or detached house up to 50 cubic metres. Homes in conservation areas, flats and listed buildings follow different rules, so we check each home first.
Do I need building regulations approval?
Yes. Every loft conversion needs building regulations approval, whether or not it needs planning permission. This covers the structure, the stairs, fire safety, insulation and electrics.
How much does a loft conversion cost?
The cost depends on the type of conversion, the size of the space and the level of finish. Each loft conversion page and each area page has a cost guide with typical ranges. A visit lets us give you a figure for your own home.
How long does a loft conversion take?
It depends on the type and size. A Velux conversion is usually quicker than a dormer or a mansard. After we have seen your loft, we give you a realistic timetable in writing.
Will I need a party wall agreement?
If you share a wall with a neighbour, as you do in a terraced or semi detached house, the Party Wall etc. Act 1996 may require you to give your neighbours notice before work starts. We explain what applies to your home.
Is the quote really free?
Yes. The quote request and the visit are free, and you are under no obligation to go ahead.
