Homes and walls in Norfolk
The East of England has a mix of post-war estates, inter-war semis and older solid brick and flint cottages, with some system-built council homes on post-war estates.
Much of Norfolk sits in the lower wind-driven rain exposure bands, which keeps the choice of finishes wide — though hilltop, coastal and exposed gable walls can still need a tougher specification, so we check the actual site.
For commercial premises in Norfolk, we programme the work around opening hours so the building can keep trading.

England: planning and regulations
For houses, external wall insulation and render are often permitted development where the finish looks similar to the existing walls. Planning permission is usually needed in conservation areas, National Parks, National Landscapes, the Broads and World Heritage Sites (where cladding a house in stone, artificial stone, pebble dash, render, timber, plastic or tiles isn't permitted development), for flats and maisonettes, for commercial buildings, under an Article 4 direction, or where the look changes noticeably. Listed buildings need listed building consent.
Renovating more than half of a wall's area — insulating it, or stripping and re-rendering it — or more than a quarter of the building's whole external envelope brings in the energy requirements of Part L, so building control needs to be involved and the wall should reach about 0.30 W/m²K where that's technically, functionally and economically feasible.
Combustible materials are banned in the external walls of relevant buildings 18 metres and over (regulation 7(2)), and Approved Document B guidance also covers residential buildings with a storey 11 metres or more above ground. Higher-risk buildings go through the Building Safety Regulator.
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.
