Homes in County Armagh
Northern Ireland has a high proportion of detached houses and bungalows outside the cities, which often suit side extensions, rear extensions and upward extensions.
What do you get with a mansard loft conversion?
Mansards are a bigger structural job than other conversions because the roof is largely rebuilt. They normally need planning permission, and many councils have design guides setting the angle, materials and window style. We prepare the design to those guides and build in slate, lead and timber or approved alternatives.
- Planning and building control applications to the council
- Planning application to local design guidance
- Roof removal and new mansard frame
How much does a mansard loft conversion cost in County Armagh?
Typical ranges for mansard loft conversions. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.

| Front and rear (double) mansard | £80,000 to £110,000 |
How is a mansard loft conversion approved in County Armagh?
In Northern Ireland the council handles both planning and building control. Permitted development rules are set by the Planning (General Permitted Development) Order (Northern Ireland) 2015, and there is no party wall act, so we agree access and protection with neighbours in writing.
This needs full planning permission from the council in Northern Ireland, plus building control approval.
What can affect a mansard loft conversion?
- The roof is open for longer than with a dormer, so weather protection matters.
- Scaffolding and a temporary roof are usually needed.
How does the project run?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.

Does a mansard need planning permission?
Almost always, because it changes the roof profile.
Why choose a mansard over a dormer?
A mansard gives more usable space and often fits a street better where neighbours already have one.
