Do you need planning permission for a two-storey rear extension in Stonehaven?
Planning for a two-storey rear extension in Stonehaven follows the Scottish householder rules.
In Scotland an extension of more than one storey is only permitted development (Class 1B) if no part is within 10 metres of any boundary and it is no higher than the existing house, so almost every two-storey rear extension needs planning permission and a building warrant.
Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development or a planning application, plus the building warrant.
What are homes in Stonehaven like to extend?
Stonehaven has sandstone villas and terraces, post-war semis and four-in-a-block flats. Flats need planning permission for an extension, and every project needs a building warrant before work starts.

FAQ
Two-storey rear extension questions in Stonehaven
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
How much does a two-storey rear extension cost in Stonehaven?
As a guide, £1,710–£2,560 per square metre including VAT for a standard specification. For example, 3 m × 5 m footprint, two floors (30 m²): about £51,500–£77,000 at that rate. Your written price follows the survey.
Can I add an en-suite upstairs?
Yes. We plan the soil pipe route early so the bathroom sits where drainage works without boxing through the room below.

Many single-storey rear extensions are permitted development under Class 1A, but not in conservation areas; you always need a building warrant before work starts.
Can you match the brick or stone on my Stonehaven house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Do I need a party wall agreement?
Scotland has no Party Wall Act; we agree access and protection with your neighbour in writing instead.
