Many Australians are joining the Granny Flat revolution with many home owners wanting to capitalise on existing properties. The Granny Flat or Secondary Dwelling is an excellent source of additional income, a place of the grandparents or for those adult children that decide to stay at home.
With the average construction cost being approximately $1000 per sqm an average granny flat construction can cost between $60,000 up to $100,000 depending on the ground condition, site access and finishes required. The cost can be quite prohibitive for some home owners. If you are an owner builder with a limited budget you might want to consider a flat pack style.
Originally designed for mining companies the Australian firm is offering the quick install prefabricated homes to the general public. Installation time is estimated to be around 4 hours.
Our construction experts advise home owner builders interested in the prefabricated granny flat to ask the following questions:
> Does the material and construction meet local building codes and standards?
> Will local council or private certifying authority approve the construction?
> What additional construction cost need to be considered for example piers, slab on ground, electrical services, plumbing etc?
> Is the design suitable for your needs?
> What are the thermal properties of the prefabricated granny flat? Will it pass BASIX requirements?
> Can you make variations to the design for example adding additional windows?
