Just remember that in the ACT there are strict disability rules and regulations you will need to comply with and your secondary residence won’t be approvable if the design does not comply with those regulations. 

Additional costs

Tie in / connection costs. 

These costs involve: 

1- Plumbing connection from the primary residence to the secondary residence (granny flat) of stormwater, sewerage, and water. 

2- Electrician connecting, internet, telephone, Foxtel, to the current house as well as installing new connection from the pole or current residence to the secondary residence (granny flat). 

NOTE: You may need to upgrade your power supply too if it’s built for a single-phase.  A secondary residence (granny flat) can take up a single phase on its own.

Site costs

Slabs: If you have existing shed, carport or garage concrete slabs, they might need to be removed. This can take time and effort, but sometimes depending on the structural build of the secondary residence the team can also work around this. 

Trees, sometimes there are significant trees on a site and will need an arborist report and approval to remove, other times the tree is not classified as significant and can just be removed by your builders. 

Gravel, sloping blocks, planter boxes or retaining walls. Sometimes these items are in the way of construction or will make the build more expensive. Make sure you get details costs that state the site costs for site works to make sure they have covered everything that needs to be required for the site. You can opt for doing this yourself if you know someone who might give you a good price, prior to building a secondary residence.  There are all things to ask and ponder over when preparing to build your new granny flat/ secondary residence

Important things to ask:

  • Do they include the Plan and Approvals?

This is an essential part of the process that can be costly and very time-consuming. You will require an architect or draftsperson to design the plans and get approval, whether that is for a full DA Approval & BA or just for BA Approval

  • Which part of the process do they provide?

i.e. a turn-key solution? Turnkey is allowing the builder to provide everything to a complete solution meaning you can move in with flooring, blinds, appliances, kitchen, television, etc.

Every builder is different and may provide it up to a different stage. You want to be very clear on what you are getting because they may not have included the flooring, blinds and fit off extras. You need to make sure there are no extra costs once you have agreed or received a final price. 

Optional extras

Other options are available, too. They come at a higher value but maybe worth extra of your money. You might want to have high-end bamboo flooring, AEG or Boshe kitchen appliances, Velux operable skylight in the bathroom to watch the stars in the shower at night, you may want a full package with all furniture provided, there are so many options. The key is to have a list of everything you could possibly want. Then markup which ones are absolute musts and work with the builder on prices to get what you want and hopefully some or all of the extras as well. 

There are a lot of options that will suit each budget and taste. A granny flat in most cases can be less expensive than building a house or adding an extension. If you want to live in it, you will have different requirements than renting it out. Make sure you know what you want to do with it and also if your plans do change in the future.

To make changes can be costly therefore try and think of as much as you can in the beginning and get quotes based on that.

Check the quotes, see displays, talk to their previous customers, and make sure you chose the right builder and they will take care of your project – And your soon to be Secondary Residence. 

All the best with your project!
