How is a granny flat priced?

  • A granny flat is priced on the square metre, the materials used and the labour to build.
  • Each builder will use different materials thereby making comparisons between companies almost impossible.
  • Building a granny flat is no different to building a house. You begin with the basics, then you add more components such as a veranda as the budget allows for.
  • However, a small 60sqm house is always more expensive to build than a larger house.
  • Building on a slab is always more preferable to stumps. However stumps construction allows for a degree in construction flexibility.

Floor plan designs

  • Designing for small spaces is more difficult to fit all the day to day amenities into one space.
  • Nova Design Granny Flats are designed by Michael who has over 40+ years of experience.
  • Where a block of land does not support a standard granny flat design, we will modify the layout to make it work.

Working to a budget

  • Based on a square metre rate, granny flats are not cheap.  But, when comparing the value of a second house on one property, and the use for which the house will be used (i.e. for rent or a relative), there is no place in Australia you can buy for the price.
  • A budget needs to be realistic especially if you are looking to increase the value of the property.
  • Adding a transportable home or 1 bed shipping container as a granny flat will not add value to the property.
  • If your funds are limited, there are ways to provide a small home and stick within a budget.  Like with everything compromises will need to be made.
