We don’t charge any extra to design a custom granny flat. The experienced team at Cubitt's can design your customised Granny Flat for the same price as a base model. We’ll take the time to understand your needs and ensure the final product is just what you envisaged. You can work off one of our stunning modern base models or come up with a design that is completely tailored to your unique needs. 

Our granny flats typically range in cost from $120,000 to $150,000, however, this price may be influenced by additions such as garages, first floors or verandahs. Our dedicated quotes team will provide you with a detailed, transparent quote prior to commencing your project – we never charge any hidden fees, what you see is what you pay.

Absolutely, we can create a unique granny flat that teams with the original design of your home. A common request from our custom granny flats clients is for their new flat to match their original property. We can finish your flat with custom cladding, brickwork or rendering to match as closely as possible that of your original property. Our design specialists can also look at incorporating elements and materials to gel your new home with your existing property such as roofing materials, windows and design themes. 

Our custom-built granny flats usually take about 12 weeks to build. Prior to building we will conduct a site visit and feasibility study and will obtain all council approvals for you. This process can take several weeks or a few months to complete. Your granny flat consultant will provide you with a detailed personalised timeframe for the completion of your custom granny flat project. 

The maximum size a granny flat can be built varies depending on which Australian state you live in.

• NSW – The maximum interior space of a granny flat is 60 m².
• ACT – The maximum interior space of a granny flat is 90 m².

The crucial thing to consider is that the space limit for a granny flat only pertains to the interior space, so outdoor areas like verandahs, garages, decks, patios and outdoor entertaining areas don’t eat into this allowance. With some creative design, your granny flat can far exceed your state’s size limits and create a spacious, welcoming custom flat.

To find out more about how to get the most out of your granny flat space allowance book a consultation with one of our experienced granny flat consultants. 

Up to 3 bedrooms can be included in your custom granny flat. Our granny flat designs can be made with one bedroom, two bedrooms, three bedrooms or as a spacious studio apartment. Alternatively, your granny flat can be made with no bedrooms at all – your custom granny flat can repurpose bedroom space as a bar, art studio, lounge room, gaming room or anything you can think of!

Yes, granny flats require either council approval or a Complying Development Certificate (CDC). You cannot build a granny flat in NSW or the ACT without obtaining one of these two options and if you try to build without them you may be liable under the Environmental Planning and Assessment Act and won’t be able to obtain an Occupation Certificate. 

At Cubitt’s, we will obtain all council approvals and other certifications on your behalf. No need to fill out endless tedious paperwork! This means more time for you to spend on the fun parts of building your custom granny flat such as selecting furnishings, paint colours and fixtures. 

Our highly experienced in-house certifications team has worked extensively with both NSW and ACT councils and can ensure an easy council approvals process for your project. We can also assist you with any additional certifications such as bushfire reports and other safety surveys to ensure everything is ready to go. We always keep our clients informed at each stage of the custom granny flat process, so we’ll provide you with detailed prices and timelines upfront on all approvals and certifications.

A turnkey granny flat is one that is ready to move into. Not all granny flat builders offer turnkey services which may lead to them having slightly lower prices or shorter build times – however, don’t be deceived! This often means you’ll need to spend more time and money adding furnishings, fixtures and utilities to your property before it can be used. 

At Cubitt’s we offer a premium turnkey granny flat service, incorporating all the finishing touches you need to have your granny flat tenant-ready the moment we hand over the keys. 

Choosing a turnkey granny flat builder like Cubitt’s to create your custom granny flat means your property will be ready to use sooner and can start generating income for you from the moment it’s completed. Plus, you won’t have to find additional tradespeople or source extra materials, everything will be taken care of by our experienced team.

A Section 10.7 certificate (2&5) is otherwise known as a Planning Certificate through council. This document gives us all the environmental information and planning requirements for development of your property/block, for example if you are: Flood affected, Bushfire affected, Mine subsidence, Heritage listed, and any other relevant zoning regulation information.

A Section 10.7 certificate is not a development approval, however, if you're looking to build, the documentation required for your approval will be dependent on what is shown in the Section 10.7 Certificate relating to your block of land. If your property is in a flood zone, you may require a flood report and may need to build the floor level of your dwelling higher, or you may not be able to build at all. Council update this information every 6 months as these factors can be impacted by development in your surrounding area, you can apply online or in person and the cost varies from Council to Council.
