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.

Before anything is agreed we visit, check the existing structure and talk through your options.

What are homes like around East Barnet?
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 East Barnet 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 East Barnet
East Barnet is in England, so the planning and building rules set out below are the ones that apply. We confirm the details with the council before we quote.
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.
From survey to handover
We look at the job
We arrange a free site survey on a date convenient to you. We measure up, look at the existing structure and access, and discuss your plans for a new porch so the price reflects your home.
Price and scope agreed
The quote arrives in writing, not over the phone. It covers the full scope, the finishes you've chosen, any exclusions and the payment schedule, with a fixed price tied to that specification.
Booking the work
Next comes planning the work itself. We set a start date that suits you, line up the right trades, and make sure any approvals for a new porch are in place before the first day on site.
The work itself
The job proceeds in the order set out in the programme, with dust and debris kept under control. Finally we tidy away, inspect the work together and pass the finished project over to you with its paperwork.
What you can expect from us
Frequently asked questions
Will a porch make my house warmer?
A porch acts as a buffer between the front door and the outside, so cold air does not rush straight in every time the door opens. This reduces draughts in the hallway or living room and can help cut heat loss. It also gives a dry place to take off wet coats and shoes. Well-insulated walls, double glazing and a good door make the biggest difference.
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.
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.
Do I need planning permission in East Barnet?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. East Barnet 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.
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.
