A patio is a paved outdoor area next to the house or in the garden, laid in porcelain, natural stone or concrete slabs on a compacted sub-base and mortar bed, with falls that direct rainwater away from the house.

Building in North Watford
Hertfordshire is home to the first garden cities, Letchworth and Welwyn Garden City, and the post-war new towns of Stevenage, Hatfield and Hemel Hempstead. Watford and St Albans have Victorian terraces and Georgian streets, interwar semis line the commuter suburbs, and brick-and-flint cottages appear in Chiltern villages to the west.
Generally dry with chalk and clay soils; clay areas can move in long dry spells, and mature trees near houses need considering for foundations.
For a new patio in North Watford, this means checking things like wall construction, roof structure and existing services before we put a figure on paper.
Planning and building rules in North Watford
Which rules apply depends on where you live. For North Watford, the answer is England, and the points below reflect that; we verify them with the council before quoting.
A ground-level patio in a back garden does not usually need planning permission in England. Raised decks or platforms more than 30 cm high do.
Building Regulations do not normally apply to patios, but levels must stay below the damp-proof course and drain away from the house.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
The four stages
Survey and measure
We arrange a free site survey on a date convenient to you. We measure up, look at the existing structure and access, and discuss your plans for a new patio so the price reflects your home.
Your fixed price
The quote arrives in writing, not over the phone. It covers the full scope, the finishes you've chosen, any exclusions and the payment schedule, with a fixed price tied to that specification.
Getting ready
With the quote agreed, we book the work in and handle preparation: permissions where needed, building control notifications, material orders and access arrangements for your North Watford property.
Finish and handover
Our trades complete a new patio while your point of contact keeps you updated. When everything is finished, we clear the site, take away waste and go through the result with you before handover.
What you can expect from us
Questions about a new patio in North Watford
How do you make sure water drains away from the house?
A patio needs a gentle fall, usually a little over 1 in 80, so rainwater runs away from the house towards the garden, a drain or a soakaway. The surface should also sit well below the damp-proof course. If the patio meets a door threshold, a channel drain may be needed. We set levels with string lines and check falls as we lay each section.
Can you combine a new patio with other work?
Yes. Because we manage several trades under one contract, we can plan a new patio alongside other work on your North Watford home, such as new windows with rendering, or a kitchen refit with an extension. Combining jobs can reduce repeat set-up such as scaffolding, skips and access, and every element is listed and priced in the same written quote.
Does a patio need planning permission?
Most patios do not need planning permission, but it depends on the size, height and location, your home's position, whether it is listed or in a conservation area, and which UK nation you are in. Raised patios or decking more than a small height above the ground may need permission because of overlooking. We check the position for your garden before quoting.
How long will a new patio take?
On a typical home, allow 3–7 days on site. Larger projects, older buildings and extra work found once things are opened up can extend that, while simpler jobs may be shorter. Your quote includes an estimate of time on site, and your point of contact keeps you updated on the programme as the work progresses.
What should I do before the work starts?
Before work starts, clear garden furniture, pots and ornaments from the area and agree where materials will be delivered and stored. We need a route for wheelbarrows and, on larger jobs, a small digger, so let us know about side gates, narrow passages or access through the house. Tell us about any known drains, cables or pipes in the area.
