What do rear extension planning drawings cost in Helensburgh?
As a guide, £1,000–£2,500 including VAT for a single-storey rear extension, or £2,000–£3,500 for a two-storey scheme. Planning and building warrant fees in Scotland are set nationally and by value of work; we confirm both before submitting. These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission for a rear extension in Helensburgh?
Planning for a rear extension in Helensburgh follows the Scottish householder rules.
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.
Scottish councils aim to decide householder applications within two months; the building warrant runs alongside.
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 Helensburgh like to extend?
Post-war semis and terraces are common around Helensburgh, and many have room for a single-storey rear extension within Class 1A limits.
