Hip to Gable Loft Conversion Arnold
Many semi-detached homes around Arnold, from Redhill to Woodthorpe, have hipped roofs that leave the loft too tight for a proper room. A hip to gable conversion builds the sloping side of the roof up into a full vertical gable wall, adding the head height and floor space you need for a real bedroom or ensuite.
We handle the whole project locally – design, structural calculations, Gedling Borough Council approvals and the build itself – with one team from start to finish.
- Free site survey and honest fixed quote
- Often built under permitted development

The right conversion for Arnold’s hipped-roof semis
Arnold has street after street of 1930s to 1960s semi-detached houses, especially around Front Street, Killisick, Redhill and the roads off Gedling Road. Most of these were built with a hipped roof – the side slopes down towards the neighbour’s boundary, which cuts the usable loft space roughly in half.
A hip to gable conversion removes that sloping side and rebuilds it as a straight, vertical gable wall in brick or blockwork with a matching finish. The roof is then extended over the new wall, instantly creating full head height across the whole loft. Most Arnold clients pair this with a rear dormer, which opens up enough space for a double bedroom with a proper ensuite.
It suits semi-detached and detached homes with a hipped side roof. End-terrace houses in Arnold with a hipped end often qualify too. Mid-terrace homes cannot have one, as there is no hipped side to convert – a rear dormer is usually the answer there instead.
Best for
Semi-detached, detached and end-terrace homes in Arnold with a hipped side roof and a loft ridge height of around 2.2m or more.
Typical outcome
A full double bedroom plus ensuite, adding roughly 15-20% to your home’s value – often more than the build cost in the NG5 market.
Why Arnold homeowners choose hip to gable
- Maximum extra space – converts wasted sloping roof into full-height, usable floor area across the whole loft.
- Often no planning application – many Arnold semis qualify under permitted development, saving time and fees.
- Cheaper than moving – gain a bedroom and bathroom for a fraction of the cost of upsizing within Arnold or Mapperley.
- Strong added value – a well-built loft bedroom with ensuite is one of the best-returning improvements in the NG5 area.
- Pairs with a rear dormer – combining both creates the largest possible loft layout, including space for a staircase that meets building regs.
- Minimal disruption below – most of the work happens from scaffolding outside, so you can live at home throughout the build.

Planning rules for hip to gable in Arnold
What you should know
Most hip to gable conversions in Arnold fall under permitted development, provided the added roof volume stays within 50 cubic metres for a semi and materials match the existing house. You will still need building regulations approval, and because the new gable sits on the boundary wall of a semi, a party wall agreement with your neighbour is normally required. Homes near Arnold’s conservation areas or with permitted development rights removed will need a full planning application to Gedling Borough Council – we check this for you at survey stage and handle all paperwork either way.

What Arnold homeowners say
“Our semi off Gedling Road had a hipped roof and the loft was useless. The team built the gable, added a rear dormer and we now have a lovely double bedroom with ensuite. Tidy workers and the tiles match perfectly.”
“They confirmed we could build under permitted development, sorted the party wall notice with our neighbour and finished in nine weeks. Communication was excellent from survey to sign-off.”
“We nearly moved house but the hip to gable gave us the fourth bedroom we needed for far less money. The quote was fixed, the site was kept clean and building control passed everything first time.”
Hip to gable questions from Arnold homeowners
Usually not. Most Arnold semis qualify under permitted development as long as the added roof volume stays within 50 cubic metres and materials match. Homes in conservation areas or with rights removed need a planning application to Gedling Borough Council. We check this free of charge at the survey.
As a guide, expect £42,000 – £55,000 for a hip to gable alone, or £52,000 – £68,000 with a rear dormer. Adding an ensuite typically brings the total to £58,000 – £78,000. Every Arnold quote we give is fixed before work starts.
If your home is semi-detached, detached or end-terrace with a hipped side roof and a ridge height of around 2.2m or more, it is very likely suitable. Most 1930s to 1960s semis around Arnold fit this description. A free survey confirms it in under an hour.
Yes, in most cases. The new gable wall on an Arnold semi sits on or near the shared boundary, so a party wall notice is normally needed. Most neighbours consent without issue, and we prepare and serve the notices for you as part of the project.
Most Arnold hip to gable projects take 6-10 weeks depending on whether a dormer and ensuite are included. Nearly all of the structural work is done from outside via scaffolding, so families stay in the home throughout with only short periods of internal disruption.
