IMPORTANT NOTES:

  • Volume cubic footage includes only new finished living space areas in your project. Attic and basement volume cubic footage is not included unless it is finished heated living space.
  • The appropriate calculator is selected based on the total floor area in square feet ( s f ) of all proposed new constructed finished living space.
  • Kitchen cabinets, countertops, and appliances are NOT part of these calculators. These costs must be added if your project includes kitchen work.
  • Normal, three fixture baths are part of basic construction. Master baths with patterned tile, jacuzzi's and other expensive fixtures and features need to be added separately to these calculators.
  • If the square footage of your project is close to the upper or lower sf range of the calculator, averaging with the next closest calculator is recommended.
  • These calculators are +/- only for preliminary guidance. You won't know the exact construction cost until you have completed the competitive bidding process.
  • TERMS DEFINED:

  • Square Feet ( sf ) __ Room length in feet X room width in feet = Square Feet Floor Area
  • Volume cubic feet ( cf ) __ Room length in feet X room width in feet X room height in feet = Volume Cubic Feet
