Planning a permeable block drive in Monmouth
Around Monmouth, plots are often larger and drives longer, so edging, falls and the route the water takes need planning.
Hilly streets in much of Wales mean many drives slope, which shapes the falls, the edging and the water route.
How much does a permeable block drive cost in Monmouth?
Most permeable block drive quotes in Wales fall within £100–£160 per m² including VAT. A 50 m² drive would usually be about £4,900–£7,900, with any extras listed separately on your quote.

What is included?
Permeable block paving is block paving built so that rainwater drains down through the joints into a deep, open-graded stone sub-base, where it is stored and soaks away slowly into the ground or is piped off. The blocks have small spacers or wider joints filled with fine grit instead of sand.
- Open-graded crushed stone (no fines) laid and compacted in layers
- Ground check: how well the soil drains and how high the water table sits
- Grit laying course and permeable blocks with grit-filled joints
- Deeper dig-out for the open-graded sub-base
- Edge restraints and any overflow or outlet the design needs
What we check on a Monmouth survey
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
- Whether front-garden planning rules apply
- Where an electric vehicle charger cable might run
- Existing manhole and inspection covers, and whether to recess them
- The kerb: is it already dropped, and is it wide enough?
Planning and kerb rules in Monmouth
Monmouth is in Wales, so these rules apply:
In Wales, any new or replacement hard surface at the front of a house should be permeable or drain to a permeable area within the property to avoid needing planning permission. Unlike England, there is no 5 m² allowance for new paving; only repairs of up to 5 m² of existing surface are exempt.
Since January 2019, construction work covering 100 m² or more with drainage implications, including drives and patios, needs approval from the local SuDS Approving Body (SAB) before work starts, even where planning permission is not needed.
A dropped kerb needs your council's approval as highway authority, and a new access onto a classified road needs planning permission.
General guidance, not legal advice. Your survey confirms what applies to your home. See the planning guide.

Permeable paving in Monmouth: questions
How long does a permeable block drive take to build?
Most homes take between three and seven working days, depending on size, the dig and the drainage. Your quote gives the expected duration.
Is the survey in Monmouth free?
Yes, for new paving here: the survey and written quote are free with no obligation. Repairs and cleaning are usually priced from photos, or from a short visit where needed.
Do I need planning permission for a permeable block drive in Monmouth?
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. Ask us on the survey if you are unsure.
Can you match the blocks to my house in Monmouth?
We bring samples to the survey and suggest blocks and borders that suit the age and brick of the house. Final colour is your choice.
