My candid advice as a professional in that field is to secure the service of a quantity surveyor to help you out with figure for your proposed building and also help you manage your project so that it won't exceed the targetted budget. Everything need will be spelt out in the bill of quantities and there will be an agree with the client and the contractor which is the builder. If a quantity surveyor to do that for you.
