Frequently asked question about granny-flats

I thought Granny Flats had to be a maximum of 60m2. Why does Cubitt’s have bigger models?

The 60m2 requirement applies only to the interior space of your Granny Flat. Additional areas such as decks, alfresco areas and garages are not included in this area requirement.

Are you guys the most expensive Granny Flat builders?

No, not by a long shot. Our Granny Flats are incredibly affordable, and we always keep your budget in mind when considering options for you.

And don’t forget, in addition to your actual build we offer unbeatable customer service. No excuses. Our motto is: one contact, zero confusion. Our highly trained staff are always available, from our design team through to the office team, your site supervisor and construction team. There is no compromise on skills and customer service at Cubitt’s.

Will I need survey reports before building can start?

Survey reports (bushfire, flood etc) are a drag. But they ensure your safety and your warranty, so they are worth doing and doing well.

We are completely transparent with you from the start about the reports you’ll need, and the costs involved. Better you know up front, and we can support you in understanding the reasons for these and the process to get moving on your build.

What EXACTLY are the standard inclusions in your base models?

Our standard inclusions are:

  • Electric oven and electric or gas cooktop with range hood
  • High-performance insulation and termite treatment
  • White roller-blind window coverings
  • Colorbond fencing and gate
  • Sliding, mirrored wardrobe doors in all bedrooms
  • TV and phone outlets
  • Bathroom exhaust-fan
  • Plumbing and electrical connections
  • 5-star energy saving Hot Water System
  • Rainwater tank and recycled water system for toilet and washing machine.
What is a feasibility study?

A feasibility study is the first action we take to give you complete assurance that your property is appropriate for building a granny flat.

Be very careful of anyone asking you for a deposit or fees for a feasibility study. This, and all of your pre-contract work with Cubitt’s, is conducted at no charge (with the exception of fees applicable to councils for surveys and certificates).

Is the council approvals process a nightmare?

At Cubitt’s we take the council dealings out of your hands – it’s all part of our service. Sometimes council approvals can take longer than expected, but we always keep you informed and supported every step of the way.

What’s more, councils are becoming more aware of how crucial Granny Flats are to affordable living in NSW and the ACT, with approvals in some parts of Sydney doubling in the last two years. As such, some councils will approve an application in as little as 10 days.

You offer a ‘complete’ or ‘turnkey’ service, but doesn’t every builder?

The short answer is no. Be really choosy about your builder – and indeed, make sure you are signing on with a builder rather than a company who will draw up your plans and just leave it to an assortment of subcontractors to figure out the construction. We see people every day looking for help with unfinished jobs.

The advantage of building with us is that we are true builders, from Ian Cubitt himself, through to our 100-person strong construction team.

We also give you the reassurance that when you indeed turn the key in your front door, your build will be complete, warranted, certified and completed with care and precision.

Check ‘Complete Service’ claims. These should include design and quote, council approvals, construction, fabrication and logistics plus after sales support and quality control.

Can you tell me over the phone whether you can build a Granny Flat on my block?

Technically, yes, and some Granny Flat builders will take your money without even visiting your site. But do you really want that? At Cubitt’s we will come to your site free of charge to review whether there are any reasons why a granny flat wouldn’t work.

While we’re there, we can talk about how one of our models would be best placed on your land, and whether you would like to look at a base model or a customised model. It’s all part of the Cubitt’s advantage – perfectly skilled, constantly committed and proudly respectful.

In your inclusions you mention Home Owners Warranty Insurance. What is that?

In NSW, any building work over the amount of $20,000 requires Home Owners Warranty insurance. The insurance covers up to the amount of $340,000. The period of cover is six years after completion of work.

In the ACT, any building work over the amount of $12,000 requires Home Owners Warranty insurance. The insurance covers up to the amount of $85,000. The period of cover is six years after completion of work.

Is a Granny Flat really a good investment?

It’s not a good investment, it’s a great investment. The return on investment for a granny flat you build on the property you live in, or on an investment property, is guaranteed to bring you a higher return more quickly than investing in any other residential real estate in NSW or the ACT.

I feel like building a Granny Flat is flimsy, not like building a real house. Isn’t it just a glorified shed?

That couldn’t be further from the truth. Come and see for yourself at one of our four exhibition centers. The message we receive the most, year after year, is that customers can’t believe the sturdiness and value of Granny Flat built by Cubitt’s.

The feeling is not of a demountable, a kit home or a modular home. We build onsite, using only the best carpenters, concreters, plumbers, electricians, tilers and more. All of who are all part of the Cubitt’s team – no untested tradesmen.

You simply won’t believe the size and structural robustness of a Cubitt’s Granny Flat, and it comes an incredibly affordable price with quality inclusions.


Are your Granny Flats like kit homes?

Again, no. Although our Granny Flats are on average the same price as a kit or modular home, they are not pre-fabricated. All of our builds are done on your specific site, to your specific plans. Your money matters and we know that when we build a Granny Flat, there should be nothing prefabricated or build-by-numbers about it. This is a home we are building with YOU in mind.
