What Affects the Cost?

Extension costs in Soham are shaped by ground conditions, foundation requirements, and local building regulations compliance. Single-storey projects typically cost less than two-storey builds due to reduced structural complexity. Material choices—brick, timber frame, or render—significantly affect budgets. Proximity to existing utilities, the need for temporary access, soil quality, and whether planning permission or Building Regulations approval is required all influence final pricing in this Cambridgeshire location.

Money-Saving Tips

Start with detailed groundworks surveys to avoid costly foundation surprises. Choose simpler designs and standard materials where possible. Obtain multiple quotes to compare builder efficiency and sourcing. Time your project during quieter seasons (autumn/winter) when builders may offer better rates.

Frequently Asked Questions

Do I need planning permission for an extension in Soham?

Most single-storey extensions under 3 metres height and certain proportions qualify for Permitted Development rights and don't need formal planning permission. However, two-storey extensions, extensions within 2 metres of boundaries, or those exceeding size limits typically require it. Always check with East Cambridgeshire District Council, as local conservation rules may apply.

What's included in a typical extension builder quote?

A full quote should include groundworks, foundations, structural frame, external walls, roof, internal finishes, electrics, plumbing, Building Regulations approval fees, and waste disposal. Confirm whether professional fees, planning applications, and contingencies are included before comparing quotes.

How long does an extension build take in Soham?

A single-storey 20 sq m extension typically takes 8–12 weeks from foundation to completion. Two-storey projects usually need 14–20 weeks. Timescales depend on ground conditions, weather, material availability, and building inspector schedules.

What's the typical cost per square metre for extensions in Soham?

Expect £650–£900 per sq m for brick and block construction, or £550–£800 per sq m for timber frame. These are labour and materials only; add groundworks (£120–£200 per sq m) and contingencies (typically 10–15% of build cost).
