Trust your granny flat build to home building experts.

Need a home office, space for the teens or in-laws?

Invest Plus can build you a quality granny flat from between $90,000 and $150,000. The cost will depend on:


  • The size of the granny flat.
  • The material you choose for the external construction such as brick, vinyl or timber cladding.
  • The fixtures and fittings you decide to use.
  • The parcel of land you are building on. A sloping block may require levelling or retaining walls.

Will an Invest Plus Granny Flat increase the value of my home property?

With the current  ‘work from home’ focus, a granny flat is fast becoming a valued space commodity for buyers looking for a new home. Families of all shapes and sizes are looking for extra habitable space for their changing circumstances. 


Typically, the increase in value of your property by adding a granny flat far outweighs the cost of construction. 


With more people working from home, kids living at home longer and grandparents cohabiting with their married children, there is already high demand for flexible co-living solutions such as a granny flat. 


If you’re thinking of building a granny flat, it is important to ensure the build is top quality, a poor quality construction will risk decreasing the value of your home.
