Moncasa large granny flats are precision built in our Gold Coast factory by our team of dedicated and experienced modular home craftsmen. They are the best in the business. It is impossible to tell the difference between a Moncasa off-site manufactured granny flat and a conventionally built on-site granny flat. Modular construction means that the home is completed in a fraction of the time it takes to build the same design onsite.

You can expect your Moncasa granny flat to be ready for occupancy within 12 weeks of placing the order.


Price of Moncasa Flagship Series

The up market Moncasa Flagship 3 bedroom, 2 bathroom granny flat is priced around $350,000 inclusive of transport and foundations. The only additional expense is site work. Site work includes DA application costs (where applicable), soil tests to ensure that appropriate foundations are used, bringing or extending utility services to the site, driveways, paths and any landscaping.

If the site is steep or uneven, additional foundation expenses may be incurred.

As our large Flagship model is over 80 squares, a Development Application is required in Queensland and NSW

Our Flagship model can also be a high quality primary dwelling well suited to smaller or steeper lots

Site inspection

You should contact your local Council for any explicit requirements that may apply to your particular property. However, for a $490 site feasibility fee (refundable), MONCASA will carry out a detailed analysis of your site to determine the optimum position for your granny flat.

That’s is the first question many people ask. Some granny flat builders, especially kit home suppliers, try to attract buyers by quoting “from $xyz”. When the erstwhile buyer finally adds up all the necessary items needed to make a turn-key home from a kit-home flat pack, they are often staggered at how “from $xyz” becomes into a massive capital outlay.

A good quality modular or traditionally built three bedroom granny flat that meets the rigorous new NCC 2022 building code, will set you back $270-$380,000. Inclusions are the major determinant of price.   Unlike Moncasa, most granny flats do not include airconditioning, decks, carports, dishwashers, floorcoverings or even blinds in their base price.

The Moncasa Large Granny Flat and its smaller versions are all constructed using 100% steel frames, and thus they are immensely strong and durable. They are built under tightly controlled conditions in a factory thus, it takes a fraction of the time a timber site build takes.

Delivery usually takes around 12 weeks.

We can arrange a visit to our factory at Burleigh Heads on the Gold Coast

Transport up to 100km from our Burleigh heads factory is included in our pricing.

Longer distances may incur a charge. The price includes everything but the variable costs of site work and supplying sewerage, water and electricity. We calculate the cost of this work for your particular site and include it in the total contracted cost of the granny flat.

Firstly it is not a relocatable home, but a permanently set home exactly the same as a an offsite home. Any modular home funding problem that is almost exclusive to Australia, because there is little competition between banks. Offsite building has become the norm in the USA and parts of Europe including Sweden and Norway (Warren Buffet owns the largest modular home company in the world and his homes are funded in exactly the same as any traditionally built home). Bank loans for off site built homes are
readily available in most other countries.

A 20% deposit is the norm for an Australian offsite manufactured home. If you have owned your property for a few years and are looking to add a granny flat, you may have built up enough equity to finance it 100% without the need for a separate deposit.  Home equity is the difference between your property’s market value and the balance of your mortgage.

We work with specialist brokers who can advise you on the accessible equity you have in your property, in order to add a granny flat.

If your property does not have enough equity to finance the build of a granny flat, you have other options. For example, a construction loan may be a suitable alternative. A construction loan may involve restructuring your current loan to include the cost of building the granny flat.

A construction loan works differently to a traditional home loan, as the funds will be available in stages to make the deposit and progress payments the builder. Again, our licensed finance brokers can assist here. There is no charge for their expert up front advice.
