What we look for in Larne
Surveys in Larne also cover the surrounding BT40 district and towns such as Carrickfergus and Newtownabbey. It's roughly 19 miles from Larne to Belfast, the largest town in County Antrim. Northern Ireland has many rendered and pebble-dashed homes, older solid-walled rural houses, and estates built by the Housing Executive.
Parts of County Antrim 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.
For commercial premises in Larne, we programme the work around opening hours so the building can keep trading.

Permissions in Northern Ireland
In Northern Ireland, permitted development is set by the 2015 Order; in Larne, changing a house's external appearance, and any work on flats or listed buildings, may need permission, so we check with the council.
External wall insulation is building work under the Building Regulations (Northern Ireland) 2012, so council building control is involved, with Technical Booklet F1 covering dwellings.
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.
How is the work programmed?
Work is split by elevation so entrances and fire exits stay usable. For schools, noisy and access-heavy stages are planned around holidays where possible. Health and safety duties under CDM 2015 are agreed at the start, including who acts as principal contractor.
