Rough Cost Estimates - Leading Construction and Building Group
A cost per square metre can only be a rough estimate when based on the same ingredients in the mix as well as the same configuration on plan and position, of a structure already built. To illustrate the misnomer of a cost per square metre consider the following: (a) Room size 4m x 5m = 20 m2 (b) Room size 10m x 2m = 20 m2.
