A porch is a small enclosed structure built over a front or side door, adding a weatherproof entrance space for coats, shoes and deliveries, improving security and reducing draughts and heat loss from the house.
County Londonderry is part of our UK-wide coverage for a new porch. Places we cover include Derry/Londonderry, Coleraine, Limavady and Magherafelt, and we travel to smaller communities across the area as well. Since your property is in Northern Ireland, the relevant planning and building rules are the ones set there. In Northern Ireland, budget around £3,000–£6,900 with VAT; the figure is confirmed after a survey that costs you nothing.

Housing across County Londonderry
Derry has Georgian and Victorian terraces around its walled city, alongside large post-war estates and newer developments. Coleraine, Limavady and Magherafelt mix older town centres with semis and estates, Portstewart has seaside villas, and rural areas have many detached homes and bungalows, often roughcast.
Terraces suit loft conversions and rear extensions, while rural bungalows commonly take extensions, loft rooms and driveways. Roughcast homes often need re-rendering, and coastal houses need roofline and window renewal.
The north coast faces Atlantic wind, rain and salt, and the Sperrins inland are colder and wetter.
Do you need permission in County Londonderry?
As County Londonderry is in Northern Ireland, read the following with that system of planning and building control in mind. We check what applies to your house with the council before you receive a quote.
In Northern Ireland, a small porch is usually permitted development within floor-area, height and road-distance limits.
Small porches can be exempt from building control approval, but glazing and electrics must comply.
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
It starts with a survey at the property, free of charge. We check condition, access and services, ask how you want the finished result to look, and answer any questions you have about a new porch.
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.
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 County Londonderry property.
Build and hand over
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
Frequently asked questions
Do you cover Derry/Londonderry, Coleraine and Limavady?
Yes. As well as County Londonderry, we cover Derry/Londonderry, Coleraine and Limavady and the rest of County Londonderry. 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 you combine a new porch with other work?
Yes. Because we manage several trades under one contract, we can plan a new porch alongside other work on your County Londonderry 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.
Can I use my porch as a room?
A porch is designed as an entrance space for coats, shoes and deliveries rather than a habitable room. If you want to use it as part of the house, for example by removing the front door between them, it is likely to need building regulations approval like a small extension, with higher insulation standards. We can design the porch to suit either use.
Does a porch need building regulations approval?
Small porches are often exempt from building regulations, provided the existing front door stays between the porch and the house and the floor area is modest. Glazing must still be safety glass and any electrics must be certified. If you remove the front door so the porch becomes part of the house, it is treated like an extension. Rules vary between UK nations, so we confirm what applies.
Do I need planning permission for a porch?
Whether a porch needs planning permission depends on its size and height, how close it is to a road, your home's location, whether it is listed or in a conservation area, and which UK nation you live in. In England, a porch is usually permitted development if its ground floor area is no more than 3m², no part is over 3m high and it is at least 2m from a boundary with a road. We check before quoting.
