2022 Updates – House Extension Estimation
- For a single-storey new extension, the price range can be around anywhere from £2,000 – £3,000 per m2, additional floor area. The minimum range would be a basic construction with UPVC windows/doors. The high range would be expensive. Note that small extensions like side return extensions will be a much higher £/m2 rate.
- For an additional storey new extension, the price range can be around £1,200 – £1,600 per m2 additional floor area. When building a second storey, you no longer have the groundwork costs, which can be considerable.
- For major structural refurbishment, the price range can be around £3,000 – £10,000 per opening.
- For loft conversion the price range can be around £1,500 – £2,500 per m2 of additional floor space (above 1500mm ceiling height). The cost of this project will eventually increase with the complexity of the project.
- For the new bathroom, the price range depends upon the design and wares you use. Likewise, it goes for a kitchen refurbishment.
All in all, the build cost will depend upon several different matrices including the complexity of design, the extent of structural works, and the level of fixtures. Always ask experts to conduct due to thoroughness on your timescale and budget consideration.
