Local considerations in Powys
Mid Wales is largely rural, with stone farmhouses, cottages and market-town terraces, many of them solid-walled.
Parts of Powys 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.
Extensions and new blockwork in Powys are where monocouche makes most sense.

Planning and building control in Wales
Permitted development rules for houses in Wales are similar to England's: a similar-appearance finish on a house is often permitted, while conservation areas, National Parks, Areas of Outstanding Natural Beauty, flats, commercial buildings and listed buildings need permission or consent. Your local planning authority has the final word.
The Building Regulations as they apply in Wales treat insulating or re-rendering more than half of a wall's area, or more than a quarter of the building's whole envelope, as renovating a thermal element, with Approved Document L (Wales) setting the target. Building control is involved before work starts.
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 Powys: 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 Powys?
Yes. We survey and quote monocouche render across Powys, including Newtown, Brecon, Welshpool, Llandrindod Wells.
Do I need planning permission in Wales?
