Granny Flat Cost

March 2, 2021

It’s one of our most frequently asked questions. At Cubitt’s, we get asked the question “How much is a granny flat?” almost every day.

The answer is, that really depends on a few things. What you want, what your budget is, and what can be built on the designated land.

The good news about Granny Flat costs is that when you come to Cubitt’s we have the people and the knowledge to give you a really accurate idea of what your Granny Flat will cost and why.

Granny flat prices will always vary because there are a number of factors that are involved. Some of these include:

  • Granny flat Style – Coastal….Hamptons……Australian Contemporary….Scandinavian Barn Style…we can build any type of Granny Flat
  • Granny flat Size – in NSW, Granny Flats can be built as large as an interior space of 60m2 and can have additional Alfresco, Carport or Garage added to the size that you require. Cubitt’s take care of it all for you.
  • Designated land condition – you may need site clearance, demolition of an old shed or garage, perhaps a tree removal permit, or arborist’s report. At Cubitt’s, we’ll tell you upfront what the council in your area requires, and how much that will cost.
  • Materials used – whether you want hardy, robust materials to withstand rental tenant or top of the line architectural finishes to perfect your designer Granny Flat look, we will be able to find the right cost for your budget
  • Complying Development or Development Application – we make it easy, no matter how complex your build requirements.

The price of granny flats in NSW will definitely range from $120,000 to $150,000 and that’s not just for Granny Flat construction! Keep in mind there are a huge amount of inclusions that come with a Granny Flat from Cubitt’s, from the slab, right through to window blinds. So if you are considering a Granny Flat versus a Kit Home or perhaps a transportable home, make sure you are comparing apples with apples. The Cubitt's team can help you all the way with this, and ensure that after you have signed up, you won't be hit by any surprise costs. What is even better is that when you build a Granny Flat with us, you know that you are getting quality. Our Granny Flat warranty covers you for seven years. Cubitt's supplies Home Owners Warranty Insurance for you from the day you sign up with us.

Don’t stress though! The Cubitt’s team is here to find you the right Granny Flat at the right price.

A Granny Flat can be built as a simple CDC – meaning a Complying Development Application (utilizing the services of a registered Private Building Certifier) or can be submitted to your council for assessment as a Development Application (commonly known as a DA) and Cubitt’s will guide you all the way through these options.

Whether you are building as a CDC or DA can have an impact on your Granny Flat cost. At Cubitt’s we will always give you the options available to you before you sign up with us, free of charge. If you are a budget-conscious Granny Flat builder, we will be able to assess your site or backyard and make the best recommendation for you to build a simple CDC-friendly design. If time is not a key factor for you, and your budget is a little more generous, you may want to build more of a deluxe granny flat in an area that suits your location preferences and tastes. This can still often be a CDC construction, however, if more complex assessments need to be made or special materials sourced, Cubitt’s have the time and expertise to make your dream Granny Flat come true.

Granny Flat shapes and sizes vary and so do the relative costs.

A one-bedroom granny flat would be perfectly suitable for older children still living at home, for extended family members, or even as a guest house. A granny flat at this size in Sydney would generally range between $120,000 to $140,000.

A two-bedroom granny flat will be a little more expensive than a one-bedroom granny flat price. A two-bedroom granny flat would be perfectly suitable for elderly parents or grandparents to move into when they are needing more assistance and care. This type of granny flat would cost around $130,000 for a minimum of three adults to be living in one granny flat.
