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.
Every house in Welwyn Garden City is a little different, so we never price a new porch from a brochure. We look at the structure, access and existing finishes first, then put in writing a fixed figure for the scope we settle on. As a rough steer, homeowners in the East of England should budget £3,700–£8,400 including VAT, with work typically taking 1–2 weeks on site.

Building in Welwyn Garden City
Hertfordshire is home to the first garden cities, Letchworth and Welwyn Garden City, and the post-war new towns of Stevenage, Hatfield and Hemel Hempstead. Watford and St Albans have Victorian terraces and Georgian streets, interwar semis line the commuter suburbs, and brick-and-flint cottages appear in Chiltern villages to the west.
Generally dry with chalk and clay soils; clay areas can move in long dry spells, and mature trees near houses need considering for foundations.
Whatever era your Welwyn Garden City home dates from, we plan a new porch around how it is actually built rather than a one-size-fits-all specification.
Planning and building rules in Welwyn Garden City
Welwyn Garden City 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.
What happens after you get in touch?
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.
Your fixed price
We put everything into a written, fixed-price quote: the specification, what's excluded, staged payments and the expected time on site. Take whatever time you need to decide; there's no pressure to commit.
Dates and permissions
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
Work goes ahead as scheduled and you deal with one contact throughout. When the last trade leaves, we clear and clean the site, talk you through what has been done and pass on any certificates and care instructions.

Common questions
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.
Who do I deal with during the job?
One point of contact manages your project from survey to handover. They schedule the trades working under our contract, keep you updated on progress, and are the person to call with any question. You don't need to coordinate builders, electricians or decorators separately, because that is part of what we do.
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.
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.
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.
