Gable-Fronted Dormers in West Midlands
We are a dormer specialist, not a general builder who occasionally does roofs — and across West Midlands that focus shows up in the detailing.
Gable-Fronted Dormers — indicative geometry
Gable-Fronted Dormers for West Midlands homes
Most of the dormer work we take on around West Midlands is on interwar semis, post-war council-built estates and Victorian terraces around the older industrial cores, where the ridge height and the position of the existing purlins set the limits.
A gable-fronted dormer runs its ridge at right angles to the main roof and finishes in a vertical triangular gable. Because the front face is flat and full height, you can fit a wider window than a hipped equivalent, and the apex is often infilled with a feature triangle of glazing or decorative bargeboard. It is the dormer most people picture when they picture a dormer.
Key specification

Planning and building control in West Midlands
Rear dormers on houses often sit inside permitted development, but the volume allowance is consumed by any previous loft or rear extension — so we check the planning history for the address before we say yes.
Building regulations approval is separate and always required. We submit the application, book the inspections around the programme and hand you the completion certificate at the end — the document a buyer's surveyor will ask to see.
Why homeowners in West Midlands use us
We would rather tell you at survey that your ridge height will not take what you want than take a deposit and find out in week three.
Send us the address and roughly what you are hoping to gain, and we will come back with a realistic answer rather than an optimistic one.

FAQs
Gable-Fronted Dormers in West Midlands — FAQs
How wide can a dormer be?
Structurally, as wide as the roof — full-width rear dormers regularly run six to eight metres, carried on a steel ridge beam. The limits are usually planning volume allowances and the setbacks needed at eaves and ridge, rather than what can be built.
What guarantees do you provide?
Structural work carries a ten-year guarantee, GRP and EPDM flat roofing twenty years, windows ten years on frames and sealed units, and lead and zinc work is covered for workmanship for ten years. You also receive the building control completion certificate, which is the document that actually matters when you sell.
Can you build a dormer in winter?
Yes, with adjustments. Temporary weather protection over the scaffold lets structural work continue in most conditions. GRP roofing needs dry conditions above about 5°C to cure properly, so in a cold spell we either sequence it differently or specify EPDM, which is unaffected.
How much does a dormer window cost?
A single flat roof dormer typically runs from around £9,000 to £20,000 supplied and fitted, depending on width, cladding finish and access. A full-width rear dormer on a semi is usually £28,000 to £45,000, and a complete dormer loft conversion including stairs, insulation, plaster and building control sign-off is more commonly £40,000 to £70,000. Our online guide-price tool gives you an indicative range in about a minute.
Does a dormer need building regulations approval?
Yes, always — permitted development covers planning, not building control. A dormer needs approval for structure, thermal performance under Part L, fire escape and protected route under Part B, and stairs under Part K if a staircase is involved. We handle the application, the inspections and the completion certificate.
