Yes — Kent's soil varies dramatically and dictates how a patio or garden build-up is detailed. Gault and Wealden clay around Maidstone and Tonbridge moves seasonally, so patio sub-bases need to be deeper and jointing flexible to avoid lifted slabs; Sevenoaks greensand and the chalk downland through Canterbury and Medway drain freely and suit shallower, permeable build-ups; Bexley's London Clay and Medway's valley alluvium need raised thresholds and piped drainage. We confirm ground conditions on site before specifying any patio or garden scheme.

Under Permitted Development, a ground-level patio is generally exempt; decking or a raised platform over 300mm above ground is not. Garden outbuildings (Class E) are permitted if single-storey, under 2.5m eaves height within 2m of a boundary, under 4m ridge height on a dual-pitched roof, and covering less than 50% of the garden — and they must not sit forward of the principal elevation. Kent's patchwork of conservation areas — the Kent Downs National Landscape, parts of Rochester, Canterbury's buffer zones, and village conservation areas across the county — often strips those rights via Article 4 directions. We check the relevant district council's conservation-area map before quoting any raised patio or outbuilding project.

Yes — the Medway valley through Rochester, Strood and lower Gillingham, the Tonbridge Medway flats, the Stour valley through Canterbury, and parts of the Thames-side coastline in Bexley all fall within Environment Agency flood zones 2 or 3. In those zones, raising ground levels or covering large areas with impermeable surfacing can affect flood storage and may trigger EA consultation before landscaping is finalised. We identify the flood-zone status at survey stage and spec accordingly — raised thresholds, piped drainage and SuDS-compliant surfaces where needed.
