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.
Homes across West Sussex vary a great deal, so we price a new porch only after seeing the property. Our coverage takes in Crawley, Worthing, Bognor Regis and Littlehampton and the surrounding districts. As a guide, expect £3,900–£9,000 including VAT in the South East; the final figure depends on size, materials and access. Any permissions are checked against the rules for England before we quote.

Housing across West Sussex
Chichester has Georgian brick streets, Downland villages use flint and brick, and Horsham stone slabs cover some older roofs. Worthing and Bognor Regis have interwar and post-war bungalows and semis, Crawley was planned as a post-war new town, and Wealden villages to the north feature tile-hanging and timber framing.
Bungalows commonly suit loft conversions and extensions; new-town homes often take window, roofline and cladding renewal. Flint and stone properties need lime repointing, and coastal homes may need external decorating more often.
Coastal towns face salt-laden south-westerly winds, while Wealden clay inland can shrink and swell with the seasons.
Planning and building rules in West Sussex
Because West Sussex falls under England's rules, the guidance below is the version relevant to you. Before sending a price, we check your property's position with the council.
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?
We look at the job
First, someone visits your home in West Sussex 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
After the survey we send a quote for a new porch that fixes the price for the scope we've agreed. If you want to change materials or scope, we revise it in writing before anything is booked.
Booking the work
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
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.
What you can expect from us
Frequently asked questions
How much does a porch cost?
A typical enclosed porch of 2–3m² costs £3,900–£9,000, including foundations, walls, roof, windows and a new door. A uPVC porch on a dwarf wall sits at the lower end, while a fully brick-built porch with a tiled roof costs more. Open canopies cost less. The door specification and moving drains or meters also affect the price. We confirm a fixed price after the survey.
How much will a new porch cost in West Sussex?
As a guide, expect to pay £3,900–£9,000 including VAT for a new porch in West Sussex. That range is adjusted for the South East, which runs about 12% 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.
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.
Do I need planning permission in West Sussex?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. West Sussex is in England, so England's rules apply. Many smaller jobs need no planning application, but some still need building control approval. We check what applies to your address before quoting.
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.
