Homes and walls in Derry~Londonderry
Surveys in Derry~Londonderry also cover the surrounding BT48 district and towns such as Strabane and Limavady. Northern Ireland has many rendered and pebble-dashed homes, older solid-walled rural houses, and estates built by the Housing Executive.
Parts of County Londonderry fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.
Schools and community buildings around Derry~Londonderry are usually phased by elevation, with noisy stages in holidays where possible.

Northern Ireland: planning and regulations
Before quoting in Derry~Londonderry, we check whether the property is listed or in a conservation area, which changes what needs planning permission in Northern Ireland.
Building control applies to insulation and major re-rendering in Northern Ireland, and the work is signed off by the council.
On taller buildings in Northern Ireland we specify non-combustible mineral wool systems and confirm the classification with building control, in line with Technical Booklet E.
Which system suits a commercial building?
The building's height, use (for example, residential or assembly use) and fire strategy shape the choice. Mineral wool systems are typical for multi-storey and public buildings; EPS may suit single-storey units. The system manufacturer's classification is confirmed in writing.
