Working in Helensburgh
Our survey diary covers Helensburgh, including G84. Neighbouring towns we cover include Dunoon (8 miles), Oban (39 miles).
Just over the Renfrewshire and Inverclyde border, Greenock is about 5 miles away. Across Scotland, extensions follow Scottish planning and building standards, including the building warrant process, which we build into the programme from the start.
Planning rules that apply in Helensburgh
In Scotland the questions are whether the extension falls within householder permitted development (Classes 1A to 1D) or needs planning permission from the council, and the building warrant, which is required before construction begins and is followed by a completion certificate.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
Building close to a public sewer needs the agreement of Scottish Water, which we check during design.
Scotland has no Party Wall Act. Where work affects a shared wall or a neighbour's land, we agree access, protection and making good with your neighbour in writing before work starts.
Applications are decided by your council as planning authority.

A lawful development certificate is not compulsory for permitted development, but it is the cleanest proof that the extension was lawful when you come to sell. We usually recommend one.

8–13 weeks typical decision period, depending on the council and the complexity of the project.

You can revise the design and reapply, or appeal. We read the officer’s report and tell you honestly which option has a better chance.
