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.
We offer a new porch throughout London, from Brent, Islington, Westminster and Bexley to the smaller places in between. Each project starts with a free survey at your home and ends with a written figure, fixed for the work you choose. Because London is in England, we work to the planning system and building standards used there, and guide prices for London run at £4,600–£10,500 including VAT.

Homes in London
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.
London Clay shrinks and swells with the seasons, and street trees close to houses can contribute to movement, which affects foundation design.
Planning and building rules in London
The notes below cover England, which is where London sits. Rules change and every property is different, so we speak to the council before pricing your job.
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.
How does the job run?
A visit to your home
A free survey comes first. It gives us what we need to price a new porch properly, including dimensions, existing materials and access for deliveries, and gives you the chance to ask anything you like.
Written quote
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.
Dates and permissions
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.
Finish and handover
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
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 London 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.
Is the price fixed?
Yes, for the specification we agree. Your written quote sets out exactly what is included at a fixed price. It only changes if you ask for something different, or if a problem the survey could not reasonably reveal later needs extra work. In either case we explain the change and confirm it in writing before going ahead.
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.
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.
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.
