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.
Whatever prompted you to look into a new porch, whether wear and tear, a growing family or plans to move, we can survey your Johnstone home and give you a price in writing. Homes in Scotland typically come in at £3,400–£7,700, VAT included, for this kind of work. We also cover Paisley, Barrhead and Erskine, and the same steps apply wherever you are in Renfrewshire and Inverclyde.

Homes in Renfrewshire and Inverclyde
Paisley has sandstone tenements and terraces from its textile era, Greenock and Port Glasgow have tenements and housing climbing the hills above the Clyde, and Gourock and Kilmacolm have Victorian villas. Post-war estates and newer private housing surround the towns, and roughcast is a common finish.
Roughcast and tenement buildings commonly need re-rendering, window replacement and roof work. Villas suit kitchen extensions and landscaping, and semis often take loft conversions and driveways.
Building traditions across Renfrewshire and Inverclyde also raise conservation and planning questions, so we check those for a new porch in Johnstone at the survey stage.
Do you need permission in Johnstone?
The notes below cover Scotland, which is where Johnstone sits. Rules change and every property is different, so we speak to the council before pricing your job.
In Scotland, a small porch is often permitted development within floor-area and height limits and away from a road boundary, but not in conservation areas.
Very small porches can be exempt from a building warrant, though they must still meet the building standards.
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?
A visit to your home
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
Next you receive a written quote with a fixed price for the agreed specification. It lists what is included, what is not, and how payments are staged, so you can compare it properly.
Getting ready
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 Johnstone property.
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.

Questions about a new porch in Johnstone
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.
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 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.
How long will a new porch take?
On a typical home, allow 1–2 weeks on site. Larger projects, older buildings and extra work found once things are opened up can extend that, while simpler jobs may be shorter. Your quote includes an estimate of time on site, and your point of contact keeps you updated on the programme as the work progresses.
Do I need planning permission for a porch?
Whether a porch needs planning permission depends on its size and height, how close it is to a road, your home's location, whether it is listed or in a conservation area, and which UK nation you live in. In England, a porch is usually permitted development if its ground floor area is no more than 3m², no part is over 3m high and it is at least 2m from a boundary with a road. We check before quoting.
