What Affects the Cost?

Extension costs in Selkirk are shaped by ground conditions—clay or wet soil can increase foundations costs—and site accessibility for materials. The scale matters greatly: single-storey work costs less per square metre than two-storey, which requires more complex structural steel and deeper foundations. Local Scottish Building Standards compliance, weather exposure in the Borders region, and the condition of your existing property also influence pricing. Labour availability and material transport distances from larger towns add modest premiums to rural projects.

Money-Saving Tips

Plan ahead to avoid rush fees and seasonal weather delays. Get multiple quotations from local builders to compare methods and materials. Consider phasing work (e.g. shell first, fit-out later) to spread costs and allow time for financing. Use local materials where possible to reduce transport costs.

Frequently Asked Questions

Do I need building control approval for an extension in Selkirk?

Yes, all extensions in Scotland require Building Standards approval. You must notify your local authority (Scottish Borders Council) before work starts. Your builder will typically manage this, and approval costs £500–£1,200 depending on project complexity. Inspections occur at key stages.

How long does a typical extension take in Selkirk?

A single-storey extension usually takes 12–16 weeks; two-storey projects take 18–24 weeks. Timescales depend on weather (Scottish winters can cause delays), site conditions, and approval processes. Your builder should provide a detailed programme.

What's included in extension builder quotes?

Quotes should itemise foundations, structural work, brickwork, roof, windows, doors, electrics, plumbing, plastering, and decoration. Ask whether scaffolding, site clearance, and building control fees are included. Some builders quote labour and materials separately.

Are extension costs higher in Selkirk than larger Scottish cities?

Selkirk costs are typically in line with or slightly below national Scottish averages. Rural locations have modest premiums for material transport and specialist labour availability, but are significantly cheaper than Edinburgh, Glasgow, or London.
