Portishead: walls, weather and approvals
Surveys in Portishead also cover the surrounding BS20 district and towns such as Nailsea and Clevedon. Portishead is about 19 miles from Bath. 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.
Exposure to wind-driven rain varies across Somerset: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.
We bring brick slip samples to Portishead surveys so you can compare them with neighbouring houses.

England: planning and regulations
Planning in Portishead follows England's national rules: similar-looking finishes on houses are usually permitted, while flats, commercial premises, conservation areas and streets under an Article 4 direction need an application.
Building control applies once more than half of a wall is insulated or re-rendered, or more than a quarter of the whole building envelope, and your written quote says how that's handled.
Are brick slips real brick?
They can be — cut or manufactured clay slips — or concrete and flexible polymer slips designed to look like brick. Clay slips are heavier and need systems rated for that weight.
