Bungalow Dormer Conversions for Berkshire homes
Most of the dormer work we take on around Berkshire is on Victorian and Edwardian terraces, interwar semi-detached houses and post-war bungalows, where the ridge height and the position of the existing purlins set the limits.
Bungalows have the best lofts in Britain: wide spans, generous ridge heights and no party walls to negotiate. A dormer conversion can add two bedrooms and a bathroom to a chalet or true bungalow, usually with dormers front and rear. The two things that decide feasibility are the ridge height and where the staircase can land without eating the hallway.
Key specification
| Typical gain | Two bedrooms plus bathroom |
|---|---|
| Ridge height needed | 2.6m+ from ceiling joist to ridge |
| Common layout | Rear dormer plus two front dormers |
| Stair | New flight, often over existing hall |
Planning and building control in Berkshire
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 Berkshire 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.
The quickest route is a photograph of the rear elevation over WhatsApp — we can usually tell you what is feasible before anyone visits.

FAQs
Bungalow Dormer Conversions in Berkshire — FAQs
Why is my dormer leaking?
In our experience the window itself is the cause less than a fifth of the time. Far more often it is the apron flashing at the dormer front, the lead soakers where the cheeks meet the roof slope, the back gutter behind a pitched dormer, or a split at an upstand in the flat covering. Water then tracks along a rafter and appears somewhere else entirely, which is why we trace the path before quoting.
Will a dormer add value to my house?
A properly built and signed-off dormer conversion adding a bedroom and bathroom typically returns a meaningful share of its cost in value, and more in areas where floor space is scarce. The building control completion certificate is what makes the space count as habitable floor area on a valuation — without it, surveyors will not include it.
Is scaffolding included in the price?
Yes. Every quotation we issue includes scaffold design, erection, weekly inspection, hire for the programme and dismantling. Scaffold appearing as an extra afterwards is one of the more common complaints about dormer work, so we price it in from the start.
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.
