What to know before a block paved patio in Caernarfon
Around Caernarfon, gardens are often larger, so falls, steps and where the water goes need planning.
Wales is wetter than most of England, and new front paving has to be permeable or drain within the property, so drainage is designed in from the start.

What you get with our patios service
Block suits patios that join a block drive or path, small or awkward spaces where large slabs would need too many cuts, and gardens where you want a pattern such as basketweave or a circle feature. We lay patios to fall away from the house and below the damp-proof course, with edging that stops the blocks creeping into the lawn.
- Falls away from the house and doors
- Dig-out and compacted sub-base (around 100 mm for foot traffic)
- Layout marked out with you, including steps and doors
- Jointing sand and compaction
- Blocks in your pattern, edges and cuts
Before we price your block paved patio
- Ground conditions and how deep the dig must be

- Trees and roots near the paving
- Manhole and inspection covers in the area
- Edges against lawns, beds, fences and walls
Do you need permission for a block paved patio in Caernarfon?
A patio or path behind the house does not usually need planning permission. Raised patios, listed buildings and flats can be different, so we check on the survey.
Paving in front of the house follows the front-garden rules: in Wales, new front paving should be permeable or drain within your boundary to avoid planning permission, and drives of 100 m² or more need SuDS approval.
