Frequently Asked Questions — Extension Builders in Helensburgh
Do I need planning permission for an extension in Helensburgh?
In Scotland, smaller single-storey rear extensions may fall under Permitted Development rights. Two-storey extensions, side extensions, and anything that significantly changes the building's footprint will usually require a planning application. Rules depend on your property type, conservation area status, and size. Always check with your local authority before starting.
What is a building warrant and do I need one for my Helensburgh extension?
A building warrant is the Scottish equivalent of building regulations approval. It is legally required for virtually all extension work including single-storey rear extensions, two-storey builds, loft conversions, and structural alterations. You submit plans to your local council before work begins. Fees range from £150–£500. Your builder should handle this but it's your responsibility to ensure it's in place.
How long does a house extension take in Helensburgh?
Single-storey rear extensions typically take 3–4 months, two-storey extensions 4–6 months, loft conversions 6–8 weeks, and garage conversions 3–4 weeks. Add 6–10 weeks for planning and building warrant approvals. Scottish weather can cause delays, particularly for groundwork and roofing.
