Local considerations in Devon
The South West has many stone and solid-walled cottages, exposed coastal properties and a share of post-war system-built houses, including types such as the Cornish Unit.
Parts of Devon 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 Devon for settled weather so each elevation can be finished in one go.

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.
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.

Monocouche render in Devon: questions
Monocouche or silicone for an extension?
Both work on new blockwork. Silicone over a base coat costs a little more but tends to stay cleaner.
Is monocouche waterproof?
It's water-resistant and sheds rain, while still allowing some vapour through.
Does monocouche need painting?
No — it's through-coloured. Cleaning every few years keeps it looking fresh.
Do you cover all of Devon?
Yes. We survey and quote monocouche render across Devon, including Plymouth, Exeter, Torquay, Paignton, Newton Abbot.
Do I need planning permission in England?
For houses, external wall insulation and render are often permitted development where the finish looks similar to the existing walls. We check your address before quoting.
