Will the council need to approve it?
In Scotland a small porch can be permitted development (Class 1C) within limits on floor area, height and distance from a road; larger porches need planning permission, and building standards still apply, so we check whether a building warrant is needed.
In a conservation area or national scenic area the householder permitted development rights are more limited, listed homes need listed building consent, and if rights have been removed by a condition or direction, any extension needs an application.
In Scotland a building warrant from the council is needed before work starts on almost any extension, and a completion certificate is issued when the work is accepted. Building standards are set in the Scottish technical handbooks.
Applications are decided by your council as planning authority.
Included in a typical project
- Front door, glazing and electrics
- Brick, render or oak frame walls
- Planning check against the porch limits
- Foundations and drainage for rainwater
- Design to suit the house style
Proportion matters on a porch more than on any other extension, because it is at the front. We match the roof pitch and brick and keep the front door in proportion with the house windows.

With the design and specification agreed, you get a fixed written price and a start date.
Build and sign-off
