Before we quote in County Londonderry
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.
We plan monocouche in County Londonderry for settled weather so each elevation can be finished in one go.

Approvals in Northern Ireland
In Northern Ireland, permitted development is set by the Planning (General Permitted Development) Order (NI) 2015. Changing the external appearance of a house may need permission, and conservation areas, flats, commercial buildings and listed buildings need planning permission or listed building consent. Check with your council's planning office.
Insulating external walls is building work under the Building Regulations (Northern Ireland) 2012, handled by council building control, with Technical Booklet F1 covering conservation of fuel and power in dwellings.
Can monocouche go over insulation?
No — insulation systems use a mesh-reinforced base coat and a thin-coat finish instead. If you want insulation as well as a new finish, see insulated render.
