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.
Planning a new patio for a home in Barnet means making a handful of decisions about materials, layout, finish and timing. We help you work through them at a free survey, then confirm in writing what it will cost for the options you pick. Most projects of this type need 3–7 days on site, and we cover every EN4, EN5, N3 and N12 address as well as the rest of London.

Homes in London
London's housing is dominated by Victorian and Edwardian terraces, often in yellow London stock brick, with Georgian terraces in central districts and mansion blocks across many inner areas. Outer boroughs have large belts of interwar semis, and there are extensive post-war council estates. Many houses have been split into flats, and conservation areas are widespread.
London Clay shrinks and swells with the seasons, and street trees close to houses can contribute to movement, which affects foundation design.
For a new patio in Barnet, this means checking things like wall construction, roof structure and existing services before we put a figure on paper.
Do you need permission in Barnet?
Planning law differs across the UK. For a home in Barnet, it is the England rules below that count, and we check them with the council ahead of any quote.
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
We look at the job
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.
Quote in writing
We put everything into a written, fixed-price quote: the specification, what's excluded, staged payments and the expected time on site. Take whatever time you need to decide; there's no pressure to commit.
Dates and permissions
Once you accept, we agree start dates, order materials and deal with any planning, building control or neighbour notices the job needs. You'll know who is coming and when before work begins.
Build and hand over
The job proceeds in the order set out in the programme, with dust and debris kept under control. Finally we tidy away, inspect the work together and pass the finished project over to you with its paperwork.

Questions about a new patio in Barnet
What happens if my garden slopes?
A sloping garden can still have a level patio by cutting into the slope, building up with retaining walls, or creating terraces with steps between them. Retaining walls must be built to hold back the soil and allow drainage behind them. This adds cost but creates usable, level space. We look at the slope during the survey and suggest the most practical design.
How long does it take to lay a patio?
Laying a typical 20m² patio takes around three to five days, from excavation and sub-base to laying, jointing and cleaning. Larger or multi-level patios with steps and walls take longer. The mortar bed needs time to set, so light foot traffic is usually fine after a day or two and furniture can go on after about a week. We confirm timings with your quote.
How do I clean and look after my patio?
Most patios just need regular sweeping and an occasional wash with water and a mild patio cleaner. Porcelain is the easiest to keep clean. Natural stone benefits from a sealant to reduce staining and from prompt cleaning of spills like oil or wine. Re-point any joints that crack or wash out. Avoid high-pressure jet washing close to joints, which can damage them.
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 Barnet 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.
