Before we quote in Dyfed
West Wales has a high share of older solid-walled and stone homes, many in exposed coastal or rural settings.
Parts of Dyfed 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 Dyfed are where monocouche makes most sense.

Approvals 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.
Where is monocouche used?
Monocouche is best on new or sound blockwork and brickwork with consistent suction — extensions, new builds and garden walls. It's applied thicker than thin-coat renders and scraped once firm to reveal the texture.

Typically 20 years or more on a suitable wall, depending on exposure and detailing.
