Home Extensions

Home extensions are relatively cost effective and extremely versatile. In the current financial climate, with London house prices continuing to increase, many families are simply priced out of the market for a new property. Fortunately, a home extension, whether this is a kitchen, wrap around extension, flat roof extension, rear extension or side return extension in London can provide you with the additional room they need at your existing property.

Depending where you are in the UK, for a straightforward extension you should allow around £1,000–£2,000/m2. 

But, the cost of the extensions will all come down to a number of factors, including size, specification and location.
Building a single storey extension will cost the following per/m2:

  • Basic quality: £1,000 to £1,680
  • Good quality: £1,680 to £1,920
  • Excellent quality: £1,920 to £2,160

 

The costs involved in fitting out a single storey extension very much depends on the room type you’re adding, a kitchen will be more expensive to equip than a home office for example, but expect to pay:

  • Between £5,000 and £30,000 for a new kitchen (higher spec kitchens can cost considerably more)
  • From around £4,500 to £11,000 for a bathroom, depending the quality of fittings; a shower room will cost a similar amount
  • Factor in between £25 to £100 per square metre for flooring
  • Add around £85 per square metre for plaster or dry-lining, plus paint if these finishes are not included in the build quote
  • Expect to spend between £1,500 to £2,000 per linear metre for bifold or sliding doors
  • Don’t forget to include the cost of adding heating to your new room. Extending an existing central heating system may only need two days’ work by a plumber, at around £150 per day (excluding materials). Underfloor heating will be more expensive. Electric underfloor heating is a cheaper installation choice (and some elements can be DIY-fitted). However, water-fed underfloor heating, although more expensive to install, and possibly requiring the addition of a new boiler to cope with the demand, is cheaper to run in the long term. Expect to pay around £2,500 for a new boiler.
