Frequently Asked Questions — Extension Builders in Hamilton

Do I need planning permission for an extension in Hamilton?

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 Hamilton 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 Hamilton?

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.

What should be included in an extension quote from a Hamilton builder?

A proper extension quote should include: a breakdown of labour and materials, groundwork, structural steelwork, building warrant fees, scaffolding, skip hire, drainage, roofing, windows, plastering, electrics, plumbing, and finishing works. It should state payment schedule (tied to milestones), timeline, and exclusions. Get at least 3 quotes and compare line by line.
