Introducing the Select Duplex Collection from Allcastle Homes
At Allcastle Homes, we recognise the need to optimise the value of your property.
A duplex home can improve the value and return on your property. You can live in one and rent the other, or rent both for an excellent return.
Building a duplex can be more cost effective than building two houses. You’re not only saving on land and build costs, but you’re also profiting from the prospect of gaining two rental incomes. So just like that, you’ve instantly doubled your investment potential.
At Allcastle Homes, our Duplexes are designed to take advantage of every square metre of land. Each duplex home has its own entry, family room and kitchen, and all have three to five bedrooms, some with studies, plus each has a separate garage or car space.
A FREE, no obligation consultation with one of our Allcastle Homes Duplex experts could save you an enormous amount of time and money and help you realise the potential for your block of land.
As an Australian family owned company, we’ve built a reputation for over 33 years for building high value, high quality family homes. We understand that every family is different, which is why each of the homes we build are unique.
Our commitment to excellence ensures that your home building experience is as seamless and smooth as possible, giving you the opportunity to live a lifestyle beyond what you imagined possible.

Is your Duplex dream achievable?
To enquire as to the suitability of building a duplex home on your property and the design features you may require, please make an appointment with one of our experienced consultants.
Allcastle Homes can organise a detailed assessment of your property including a full AHD detailed survey of your land, and obtain a 10.7(2) zoning certificate from Council, a sewer diagram and planning advice.
A detailed proposal will then be provided based on this information. All proposals are subject to approval and requirements of approving authorities.
Based on the proposal, the client would proceed to pay a ‘Plan Preparation Fee’ for the preparation of working plans for either a Development Application (DA) with Council or Complying Development Certificate (CDC) approval. In some circumstances approval can be obtained for sub-division, however this is not guaranteed.
Let us do all the hard work for you!
Once you’ve made the decision to build with Allcastle Homes, the rest is pretty stress-free. We guide you through every step of the process from start to finish.
So why wait? Talk to an Allcastle Homes consultant today and find out if your Duplex dream is achievable.
