It is very difficult to put a fixed figure to a project until you have some idea of its scope as there are a lot of variables that have an affect on the final cost of a building. Some examples from a long list include:
  • What materials will be used for the building’s construction?
  • How big is the building?
  • How complex is the design?
  • Are the fittings and finishes of a high quality?
  • Where is the site ?
  • Is the site difficult to work on – e.g.. steeply sloping, limited access, etc
As a rough guide, the cost of a “project home” could range from $1,000 – $2,000 per square metre, whereas a custom designed home could range from $2,800 up to $4,000 or more per square metre for luxury homes. These rates relate to the building only and do not include things like landscaping, pools, driveways, earthworks etc. It is highly recommended that a cost estimator or pre-selected builder be engaged as part of the design team to help advise you on cost and budget planning.
