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.

What are homes like around Derry/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.
Knowing the typical building types in County Londonderry helps, but a survey of your own home in Derry/Londonderry is what decides the right approach to a new porch.
Do you need permission in Derry/Londonderry?
Which rules apply depends on where you live. For Derry/Londonderry, the answer is Northern Ireland, and the points below reflect that; we verify them with the council before quoting.
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
Free site survey
First, someone visits your home in Derry/Londonderry 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.
Price and scope agreed
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
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
On site, the agreed plan is followed and any change is put in writing first. At completion we do a final clean, go through the snagging list with you and leave you with the relevant documents.
Why homeowners choose us
Porches in Derry/Londonderry: questions
What if there is a gas meter or drain where the porch will go?
A gas or electric meter box or a drain in the porch area does not usually stop a porch being built, but it affects the design and cost. Meters may need moving by the supplier, which takes time to arrange. Manholes can sometimes be enclosed with a sealed cover, depending on the drainage. We check these details at the survey and include them in the quote.
How long will a new porch take?
On a typical home, allow 1–2 weeks on site. Larger projects, older buildings and extra work found once things are opened up can extend that, while simpler jobs may be shorter. Your quote includes an estimate of time on site, and your point of contact keeps you updated on the programme as the work progresses.
What happens at the survey?
We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from a new porch, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
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.
What style of porch suits my house?
The right porch style usually echoes your house. Brick-built porches with a tiled roof suit traditional brick homes, while uPVC or aluminium porches suit newer houses and give more light. Matching the roof pitch, brick colour and window style to the house helps the porch look as if it has always been there. We bring photos and options to the survey.
