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.
In Carmarthen, as anywhere in Dyfed, the price of a new patio is driven mainly by size, materials and access. Across Wales our guide sits at £2,300–£5,100 with VAT, but restricted parking, a narrow side passage or extra preparation can move the figure either way. That is why every price we give follows a visit to the house.

How much does a new patio cost in Carmarthen?
To help you plan, we show what a new patio typically costs in Carmarthen instead of holding figures back for a sales call. The range is £2,300–£5,100 with VAT, using rates in Wales that are about 8% below the national guide. A free survey then fixes your actual price.

Local housing and a new patio
Dyfed covers Carmarthenshire, Ceredigion and Pembrokeshire. Stone cottages and farmhouses under slate roofs are common, often rendered or colour-washed, as in Tenby's brightly painted terraces. Llanelli has Victorian industrial terraces, Aberystwyth and Carmarthen have Georgian and Victorian centres, and bungalows and newer estates surround most towns.
Stone homes often need lime render, repointing and roof slating repairs. Terraces suit loft conversions and extensions, and rural bungalows commonly take extensions, porches and driveways.
None of this holds for every street in Carmarthen, which is why we look at your actual house before pricing a new patio rather than assuming from its age alone.
Planning and building rules in Carmarthen
For anyone in Carmarthen, the relevant framework is Wales's. The summary below is general, so we always contact the council about your address before putting a price in writing.
A ground-level patio does not usually need planning permission in Wales; raised platforms are more restricted.
Building Regulations do not normally apply, but levels and drainage must protect the house walls.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
What happens after you get in touch?
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.
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.
Plan and prepare
We handle the paperwork side: checking whether planning permission or building control approval is needed, submitting applications where they are, and scheduling the trades and materials around your dates.
On site to finish
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.
What you can expect from us
Frequently asked questions
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 Llanelli, Ammanford and Gorseinon?
Yes. As well as Carmarthen, we cover Llanelli, Ammanford and Gorseinon and the rest of Dyfed. 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.
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.
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.
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 Carmarthen 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.
