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.
We offer a new patio across Cornwall, and St Austell is one of the places we cover, along with nearby Truro, Newquay and Falmouth. Before anything is agreed we visit, check the existing structure and talk through your options. You then receive a written quote setting out the full scope; for most homes in the South West it sits within £2,600–£5,600 including VAT.

Local housing and a new patio
Older Cornish homes are often built of granite or slatey local stone, with slate roofs and sometimes slate-hung walls facing the weather. Cob cottages survive in places, Truro and Falmouth keep Georgian and Victorian streets, and many towns have rendered post-war houses, bungalows and newer estates on their edges.
Cornwall faces Atlantic gales, driving rain and salt-laden air, so render, pointing and window hardware on exposed elevations need a suitably robust specification.
For a new patio in St Austell, this means checking things like wall construction, roof structure and existing services before we put a figure on paper.
Planning and building rules in St Austell
The notes below cover England, which is where St Austell sits. Rules change and every property is different, so we speak to the council before pricing your job.
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
First, someone visits your home in St Austell to see the space, take measurements and note anything that could affect the work, such as access or the condition of what is there. There is no charge for this visit.
Quote in writing
After the survey we send a quote for a new patio that fixes the price for the scope we've agreed. If you want to change materials or scope, we revise it in writing before anything is booked.
Booking the work
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.
The work itself
The work is carried out to the agreed specification, with floors and furniture protected and the site kept tidy. At the end we clean up, walk through the finished job with you and hand over any certificates.
How we work
Questions about a new patio in St Austell
Is porcelain or sandstone better for a patio?
Porcelain is dense, stain-resistant and stays looking clean with little care, making it a good choice if you want a modern, low-maintenance patio. Indian sandstone has natural colour variation and a softer, traditional look, and costs a little less, but it can stain and weather over time and benefits from sealing. Both make durable patios when properly laid. We bring samples to the survey.
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 St Austell 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.
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.
Do you cover Truro, Newquay and Falmouth?
Yes. As well as St Austell, we cover Truro, Newquay and Falmouth and the rest of Cornwall. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.
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.
