Hard landscaping—patios, paths and driveways—often falls within permitted development when it is at ground level, does not form a raised platform above certain thresholds next to the dwelling, and does not create new access over a footpath or highway without consent. Because the detailed rules are height- and context-specific, always cross-check your design against current government guidance (for example via the Planning Portal) or ask your LPA for a quick steer.
Garden walls and fences
Fences, gates and walls may be permitted up to defined heights depending on location—especially next to highways or boundaries. In front gardens facing a highway, limits are typically stricter. In conservation areas, listed building curtilages or where an Article 4 direction applies, permissions can be tighter or PD may be removed.
Outbuildings, sheds and garden rooms
Detached garden buildings within certain size, height and position limits can be permitted development, again subject to not occupying more than a set proportion of the curtilage and not being used as self-contained living accommodation in breach of conditions. Decking and platforms can affect whether height is measured from “natural ground level,” so professional drawings help avoid surprises.
Building Regulations
Even when planning permission is not required, some patios and drainage works interact with Building Regulations—for example where they affect damp proof courses, rain-water disposal, or accessibility routes. Structural retaining walls may also need structural input.
Working with a contractor
At Kene Building Services we routinely lay patios and deal with levels, falls, sub-bases and surface water. We can work to your approved drawings and flag practical constraints early. For formal planning or Certificate of Lawfulness applications, we will direct you to your designer or LPA as appropriate.
