Adding an extension to a house: cost

- Double storey: £80,000
How to choose house extension builders
Of course, price is a major deciding factor in choosing the right home extension builders
for you. But remember it doesn’t all come down to cost. Getting the best balance of quality and expense is key.
This is where testimonials from previous clients come in. Read reviews, speak with the home extension company you’re interested in using, and take your time deciding which one you’re most comfortable with. Free consultations/schedules of work, detailed cost breakdowns, and 24/7 communication with your project manager are all benchmarks of reputable companies.
Look for industry memberships and accreditations to gain more peace of mind that the home extension contractors you’re considering are reliable and trustworthy. You’ll feel in safe hands by using an NHBC-registered licensed company, like Fittra Construction. Check their level of public and products liability insurance, too, and employer’s liability insurance. Accreditations could include:
- NFB (National Federation of Builders)
- FMB (Federation of Master Builders)
- NHBC (National House-Building Council)
- Considerate Constructors
- TrustMark
