What Affects the Cost?

Extension costs in Royston depend on several key factors: project scale and design complexity, material quality and specification, ground conditions requiring different foundation solutions, planning permission and building regulation approvals, proximity to utilities, and the need for party wall agreements with neighbours. Older properties may require additional work for proper tie-ins and structural support. Market demand and builder availability also influence pricing.

Money-Saving Tips

Obtain detailed quotes from 2-3 builders to compare specifications. Consider phasing larger projects to spread costs. Source materials yourself for potential savings, but clarify this with builders beforehand. Simplify designs to reduce labour time—box shapes cost less than complex angles or multiple roof lines.

Frequently Asked Questions

What does a typical single-storey extension cost in Royston?

A standard 15-20 sqm single-storey rear extension ranges from £18,000 to £35,000 depending on specification, finishes, and site conditions. Budget for foundations, brickwork, roof, windows, doors, and internal finishes. Additional costs apply if utilities need relocating.

How long does an extension build take?

A single-storey extension typically takes 3-5 months from foundation to completion. Two-storey extensions require 5-8 months. Timescales depend on complexity, weather delays, and inspector sign-offs. Discuss project timeline with your builder before contracts are signed.

Do I need planning permission and building regulation approval?

Most extensions require building regulation approval; planning permission depends on size, location, and local policies. Permitted development rights may apply for small single-storey extensions. Your builder can advise, but consult your local authority or a planning consultant. Costs typically add £500-£1,500.

What's included in an extension builder's quote?

A comprehensive quote covers foundations, structural frame, brickwork, roof, windows, doors, internal walls, flooring, and basic finishes. Clarify whether electrical, plumbing, heating, and decorated finishes are included, as these vary significantly between quotes.
