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 Castlereagh 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 BT2, BT4, BT5 and BT6 address as well as the rest of County Down.

Building in Castlereagh
County Down takes in suburbs of Belfast, Bangor and Holywood with Victorian and Edwardian villas, and Newry, Downpatrick and Banbridge with older town centres and newer estates. Mourne granite appears in buildings around the mountains, and detached rural homes and bungalows are common across the county, often rendered or pebbledashed.
Villas and semis suit kitchen extensions, loft conversions and garden landscaping. Rural detached homes commonly take extensions and driveways, and rendered houses often need re-rendering, roofline renewal and window replacement.
Knowing the typical building types in County Down helps, but a survey of your own home in Castlereagh is what decides the right approach to a new patio.
Planning and building rules in Castlereagh
Castlereagh is in Northern Ireland, so the planning and building rules set out below are the ones that apply. We confirm the details with the council before we quote.
A ground-level patio does not usually need planning permission in Northern Ireland; raised platforms are more restricted.
Building control approval is not normally needed for a patio.
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?
Free site survey
We begin by looking at the job in person. During the free survey we discuss options, materials and budget for a new patio, and photograph or measure anything the quote needs to reflect.
Quote in writing
We turn the survey notes into a written quote. The price is fixed for the specification we agree, and the document sets out materials, scope and payment stages in plain language.
Plan and prepare
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 Castlereagh property.
On site to finish
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.
How we work
Frequently asked questions
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 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.
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.
Do you cover Belfast, Newtownabbey and Lisburn?
Yes. As well as Castlereagh, we cover Belfast, Newtownabbey and Lisburn and the rest of County Down. 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.
Can I stay at home during the work?
In most cases, yes. Most people can live at home throughout, and we plan the work to keep disruption down by protecting floors, agreeing working hours and keeping access routes clear. Bigger jobs affecting kitchens, bathrooms or heating may mean a short spell with reduced facilities, and we talk this through with you at the survey.
