Prices are indicative averages for Devizes. Actual quotes will vary based on job specifics.

What Affects the Cost?

Extension costs depend heavily on project scope: single-storey extensions cost less than two-storey builds, which require more complex structural work. Material choices—brick, stone, render finish—significantly impact the budget. Location matters too; properties in Devizes town centre may face stricter planning constraints than rural areas. Ground conditions, existing electrics and plumbing to relocate, and whether the extension includes new services all add costs. Quality of finishes, local labour availability, and current material prices in the South West also play key roles.

Money-Saving Tips

Book a consultation during the quieter winter months when builders may offer better rates. Get multiple quotes from local Devizes builders to compare pricing approaches. Plan your project to avoid costly amendments during construction—thorough upfront design prevents expensive mid-build changes. Consider phasing work: build the shell first, then finish interiors later if budget is tight.

Frequently Asked Questions

What's included in an extension builder's quote?
A comprehensive quote should cover foundations and structure, brickwork/blockwork, roof, windows and doors, electrics, plumbing, insulation, plastering, flooring, and final decoration. Always check whether scaffolding, skip hire, and Building Regulations approval are included, or charged separately. Labour, materials, and site management should all be itemised.
Do I need planning permission for an extension in Devizes?
Many single-storey extensions up to 40 cubic metres qualify for Permitted Development Rights in Devizes, but two-storey extensions almost always need planning permission. Extensions near conservation areas or Listed Buildings have stricter rules. Your builder should advise, but contact Wiltshire Council Planning to confirm your specific property's requirements.
How long does a typical extension take in Devizes?
A small single-storey extension (15-20 sqm) usually takes 12-16 weeks. Larger two-storey projects can take 6-9 months or longer. Weather, site conditions, and approval timelines affect schedules. Always allow buffer time in your planning. Experienced local builders understand Devizes' seasonal factors and can advise realistically.
Are there any cost-saving tips specific to the Devizes area?
Using locally-sourced materials (stone, slate) may be cheaper than importing specialist finishes. Devizes has good access to building suppliers in nearby Bath and Swindon. Avoid peak building season (April-September) if possible—labour and material costs spike. Building in winter is slower but often cheaper.
