*How Much Does an Extension Cost? *

When the plans are approved, local London builders will provide you with detailed quotes, with a view to signing a contract.

The cost of a London Home Extension will vary greatly depending on the type of property you own and your requirements. While there is no precise formula for obtaining an accurate cost for your extension , builders have worked out an indicative price guide for building extensions in London.

A typical ground floor extension may cost around £30,000 - £50,000.

The price will vary depending on several factors such as location of the house; ground conditions; quality of finishing; electrical and plumbing work; kitchen and bathroom fittings, and the type of extension required.

One-storey extensions are more common, however two-storey extensions can create additional space without going into the loft. Adding a two-storey extension doesn’t mean that it will cost you twice as much. Just multiply the figure for a single storey by two, and deduct 20% to get a rough idea of the cost.

The most common size of extension is 15 to 25 square meters, which can have construction costs between £20,000 and £35,000 (excluding the interior fitting). The cost for interior fitting can range from £10,000 to £20,000 for a small single-storey extension.

Approximate Home Extension Costs for London

Planning Costs £1,000 - £3,500
Single Storey £20,00 – £65,000
Double Storey £20,000 - £115,000
Shell build cost (windows, external doors, roof etc.) £600 per m2
Fixtures & Fittings (electrical, plumbing, plastering, flooring) £400 per m2
Decoration Finishing £10-15 per m2

The given costs will vary depending on your design preferences, as well as availability of contractors and materials.

It is always advisable to add between 10% and 15% on top of the estimated cost, to allow for any unexpected price fluctuations.

Estimating Building Costs – New Builds

It tends to be much less expensive to build your dream home from scratch than to buy a pre-built home. The price per square meter in the UK ranges from around £550 to £1,500, which means that the average cost to build a 100m2 house is only £77,500, excluding excavation, walkways, driveways and furnishing.
