Covering Taunton
Our coverage around Taunton (TA1) also includes Bridgwater, Burnham-on-Sea and Tiverton.
Homes in the South West
The South West mixes stone and render cottages, Victorian terraces in the larger towns and modern estates, and many historic centres are conservation areas where materials and roof shapes are closely controlled.
What goes into a dormer loft conversion?
Rear dormers on terraced and semi-detached houses are often permitted development in England. We size the dormer to fit the volume allowance, clad it to suit the house (tile-hanging, render, slate or zinc) and fit out the room and en-suite below.
- Dormer frame, roof covering and cladding
- Staircase, insulation and plasterboard
- En-suite, electrics and fire-protected escape route

What approvals does a dormer loft conversion need in England?
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.
In England many loft conversions are permitted development: the extra roof volume must stay within 40 m³ on a terraced house or 50 m³ on a semi or detached house, nothing can sit higher than the existing ridge, no dormer can face a road on the main elevation, and side windows must be obscure-glazed and non-opening below 1.7 m.
What should I think about before starting?
- Dormers on the front of the house facing a road are not permitted development in England.
- L-shaped dormers are common on Victorian terraces with a rear outrigger.

Is a dormer permitted development?
Rear dormers in England often are, within the 40 m³ (terrace) or 50 m³ (semi or detached) volume allowance. Front dormers facing a road are not.

Yes. The full head height in a dormer makes it the best place for a shower room or en-suite.
