Dormer Loft Conversions — indicative geometry
Dormer Loft Conversions for Perthshire and Stirlingshire homes
Most of the dormer work we take on around Perthshire and Stirlingshire 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.
A dormer loft conversion is the whole sequence: steels and a new floor structure, the dormer itself, a compliant staircase, fire-rated doors and a protected escape route, insulation to current Part L, electrics, heating and plaster. Building control sign-off is what turns loft space into habitable floor area on a survey and on a mortgage valuation — and it is the part people skip at their peril.
Key specification
| Floor area gained | 15m² – 30m² typical |
|---|---|
| Head height required | 2.2m+ over the stair landing |

| Compliance | Part L, Part B fire, Part K stairs |
Planning and building control in Perthshire and Stirlingshire
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.

FAQs
Dormer Loft Conversions in Perthshire and Stirlingshire — FAQs
Can you build a dormer on a bungalow?
Usually yes, and bungalows often give the best results because the spans are wide and there are no party walls. The deciding factor is ridge height: you generally want at least 2.6m from the top of the ceiling joists to the underside of the ridge. We measure this at survey before committing to anything.
Can I put a dormer on the front of my house?
Front-facing dormers are not covered by permitted development and always need a full planning application. Approval depends heavily on the street scene — planners look at whether other dormers already exist on the road, and at proportion, position and materials. Hipped and pitched forms are approved far more often than flat boxes on a front elevation.
Do you handle the planning application?
Yes. We prepare measured drawings, elevations and sections, submit the application or the lawful development certificate, and deal with the case officer's queries. On conservation and listed work we also put together the heritage justification the application needs.
What is the difference between a dormer and a Velux?
A rooflight sits flush in the roof slope and gives you light without any extra height — you still have a sloping ceiling. A dormer projects out from the roof and creates vertical walls with a level ceiling behind them, so you gain genuinely usable standing space and floor area, not just daylight.
Do you work on listed buildings and in conservation areas?
Yes. That work is detail-led: matching sightlines, glazing bar widths, cill projections and cheek finishes to what survives, and specifying timber, lead and natural slate rather than modern equivalents. We prepare the drawings and heritage statement for listed building consent alongside the planning application.
