What is a porch?
A porch is a small extension built around the front door, giving a lobby for coats and shoes and stopping draughts reaching the hall. Most are brick with a pitched tiled roof to match the house, though glazed and timber porches are also common.
How much does a porch cost in Johnstone?
In Johnstone, a porch typically costs £6,250–£15,500 from a 3 m² porch to a small front extension, including VAT at 20% (standard rate). Prices in Scotland sit near the national average for this kind of work, and the range for Johnstone reflects that. Design, structural calculations and council fees are extra.

|---|---|

Your quote will depend mainly on:
- Size and roof style
- Whether building regulations apply
- Front door specification
- Brick matching
A guide range is only a starting point: the guide price tool gives an instant figure for your size, and a free survey turns it into a fixed quote.
Do you need planning permission for a porch in Johnstone?
The approval route for Johnstone is set by planning law in Scotland. In Scotland a porch is permitted development if its footprint is no more than 3 square metres, it is no more than 3 metres high and more than 2 metres from a boundary with a road, outside conservation areas. A building warrant may be needed depending on the design.
Scotland has no Party Wall Act. Work on shared walls is governed by your title deeds, the Tenements (Scotland) Act 2004 for flats, and common law, so we agree arrangements with neighbours in writing before work starts.
We check this for your address before design work starts, so there are no surprises later.
