How to estimate the cost of building a house per square meter

There are many ways to estimate the cost of building a house. While not necessarily the most accurate method, use the Total square meters of the house and a rule of thumb dollar per square meter for the area and type of home is an easy way to get a notion about the potential cost.


  1. Calculate the square footage. Although this seems very simple, an important factor that can skew an estimate of the construction cost is the difference between the square meters finishes and square meters, including areas such as basements or garages that do not receive the same level of work and therefore they cost less. Unfinished rooms such as basements and garages are not free to build, so are excluded from the estimate producing an artificially low figure.
  2. Identifies the price per square meter per regions and styles. Most cost estimates are given by region and assume an average house. If your home is not normal, that is, for example, you will include a luxurious interior or exterior finishes and high quality materials, using the average cost per square meter in the region will fail. Consult the manufacturer the best square footage estimated on the basis of the plan of your private home.
  3. Multiply, and if necessary, sum. In the simplest but less accurate calculations, multiply the square footage by the cost per square meter. A more accurate estimate can be obtained using different estimated costs per square meter of finished and unfinished space and adding the total amount of these areas together.
  4. Anticipates excesses. A cost estimate is just that, an estimate. Do not be surprised if only for a project incidentals (such as, for example, leveling the ground) cause the actual total cost is somewhat higher, even up to 10 to 15%. However, this does not mean that the cost cannot be less. Understand your estimate to represent an area in which the total cost is likely to fall. Do not agree a plan that is too expensive, or the excesses of routine can jeopardize funding.

Tips & Warnings

  • By working with a builder or architect, you can dramatically change the cost per square meter of a house design changing window styles, materials and other features. Asked by several different estimates based on different configurations to get the most out of your money.
  • Construction costs are always changing, so not necessarily based on an estimate old.
    Many estimates of cost per square meter do not consider unfinished areas or different levels of quality of construction.
  • When you get a cost estimate based on the square footage sure to determine how the particular estimation addresses these factors.
