Do you need planning permission for a two-storey rear extension in Dalserf?
Whether your two-storey rear extension in Dalserf needs a planning application depends on its size, your house and any local restrictions.
Scottish Class 1B rights for extensions of more than one storey need a 10 metre gap to every boundary, which few gardens have. Expect a planning application as well as a building warrant for a double-storey rear extension.
Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Dalserf like to extend?
Dalserf 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.

Two-storey rear extension questions in Dalserf
How much does a two-storey rear extension cost in Dalserf?
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.
Do I need planning permission for a rear extension in Dalserf?
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.
Is two-storey cheaper per square metre than single-storey?
Usually yes, because the foundations and roof are shared across twice the floor area. The total cost is higher.
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
Do I need a party wall agreement?
Scotland has no Party Wall Act; we agree access and protection with your neighbour in writing instead.

Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
