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.
Homeowners in Coulsdon usually consider a new porch for one of a few reasons: something has worn out, the house no longer suits the way they live, or they are getting it ready to sell. We visit, agree a specification and put a fixed price in writing. Most jobs like this take 1–2 weeks on site, and we work across London, including Purley, Banstead and Wallington.

Building in Coulsdon
London's housing is dominated by Victorian and Edwardian terraces, often in yellow London stock brick, with Georgian terraces in central districts and mansion blocks across many inner areas. Outer boroughs have large belts of interwar semis, and there are extensive post-war council estates. Many houses have been split into flats, and conservation areas are widespread.
Terraces suit side-return extensions and rear dormer loft conversions; interwar semis commonly take hip-to-gable lofts. Shared party walls, restricted parking and conservation rules often shape the plans and the programme.
If your house in Coulsdon fits one of these patterns, it helps us anticipate what a new porch will involve, though we always confirm the details on site.
Permissions for a new porch in Coulsdon
Which rules apply depends on where you live. For Coulsdon, the answer is England, and the points below reflect that; we verify them with the council before quoting.
In England, a porch is usually permitted development if its ground floor area is no more than 3 m², no part is higher than 3 m, and it is at least 2 m from any boundary with a road.
Small porches at ground level are usually exempt from Building Regulations if the front door stays in place between porch and house, but safety glazing and any electrics must still 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
Book a visit and we'll come to you. The survey covers measurements, the state of what's there now and any obvious constraints, so the price that follows is based on your actual home, not an average.
Your fixed price
You get the price in writing, itemised so you can see where the money goes. As long as the specification stays the same, that is the price you pay for a new porch.
Booking the work
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 Coulsdon property.
On site to finish
During the work we protect the areas around it and tidy up at the end of each day. Once complete, we check the finish, remove our materials and hand over paperwork such as building control sign-off where it applies.
Why homeowners choose us
Questions about a new porch in Coulsdon
How long does it take to build a porch?
Building a porch usually takes one to two weeks on site. Foundations and base go in first, then the brickwork, roof, windows and door. uPVC and aluminium porches are often quicker because the frames are made off-site, while brick-built porches with a tiled roof take a little longer. Frames and doors are made to measure, so allow a few weeks' lead time before starting.
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.
Which postcodes in Coulsdon do you cover?
We cover CR5 and CR8, along with the rest of London. If your postcode is not listed, get in touch anyway: our coverage is UK-wide, and we can usually arrange a survey wherever you live. Enter your postcode in the guide-price tool or contact form and we will confirm.
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.
How much will a new porch cost in Coulsdon?
As a guide, expect to pay £4,600–£10,500 including VAT for a new porch in Coulsdon. That range is adjusted for London, which runs about 30% above the national guide. Where your project lands depends on size, materials, access and the condition of what is already there. We confirm a fixed price in writing after a free survey of your home.
