The cost details provided in HB&R are excellent. However one item that is troubling is the difference between the guideline costs provided by the RICS compared with that given by architects.
In Oxfordshire the RCIS numbers suggest a build cost of around £1000per sqm. However, mention that to architects and they look aghast – two have said that £1900 per sqm is a much more realistic guide and a third suggests that by doing a great deal of self management and DIY, it might – just – be possible to reach £1500 per sqm. Even a chartered accountant agrees with these numbers (absolute minimum cost of £1500 using key labour and materials sourced at lowest prices, and a lot of self management and DIY)
How is this vast difference between the RCIS and local professionals explained?
