Single Storey Homes

Allcastle Homes single-storey residences are designed for low-maintenance living without compromising on space or luxury. These homes maximise indoor-outdoor flow, featuring open-plan living areas, spacious bedrooms, and modern kitchens. Ideal for families seeking accessibility or downsizers prioritising ease of movement, our single-storey designs adapt to narrow or wide blocks. With energy-efficient materials and a focus on natural light, these homes blend comfort and sustainability. Customers can customise layouts and inclusions at our Infinity Selection Centre.

Double Storey Homes

Our double-storey homes optimise vertical space to deliver expansive living areas across compact or standard blocks. Featuring multi-functional zones, such as home theatres, study nooks, and oversized alfresco areas, these designs cater to growing families. The lower levels prioritise entertaining spaces, while upper levels offer private retreats. Allcastles two-storey range includes options up to 48.5 squares, with premium finishes and structural integrity. Customisation ensures alignment with lifestyle needs, from sloping sites to Sydneys urban landscapes.

Duplex Designs

Allcastles duplexes provide versatile dual-living solutions, ideal for extended families or investment purposes. Each unit maintains privacy with separate entrances, while shared walls reduce construction costs. Designs include mirrored layouts or distinct configurations for flexibility. Features like oversized garages, spacious kitchens, and zoning compliance ensure practicality. The Elmsworth Duplex, showcased at HomeWorld Warnervale, exemplifies our commitment to modern aesthetics and functional design tailored to Sydneys regulatory standards.

Granny Flats

Our granny flats offer self-contained living spaces for elderly relatives, guests, or rental income. Ranging from compact 1-bedroom units to larger 3-bedroom designs, these dwellings comply with NSW planning regulations. Key features include kitchenettes, accessible bathrooms, and seamless integration with main residences. Customers can choose standalone or attached configurations, with customisation options for finishes and layouts. These units enhance property value while addressing multigenerational living needs.

House & Land Packages

Allcastles house-and-land packages simplify the building process by combining land acquisition and construction into one transaction. Available in Sydneys growth corridors, these packages include pre-approved designs suited to specific blocks. Benefits include cost savings, council DA assistance, and fixed-price contracts. Packages cater to first-home buyers, investors, and families, with options for narrow blocks, sloping sites, or knockdown rebuilds. Transparent pricing and inclusions ensure no hidden costs during the build.

We havent even begun building yet so I dont know what other nightmares I will experience
since last year in May I have received at least 8 tenders for quotes on what we had chosen..when at the display home we had said we will take this kitchen these bathroom vanities and bath tub and toilets that were in the display house. Only to find out when choosing colours, that our kitchen shown to us at the display was NOT the one quoted on the tenders..on the contracts it did not state that we were getting the basic kitchen which was not on show or ever seen..the vanities in the upstairs bedrooms

We are still in finalising contract stage. Luckily, we had Brad Miller helping with initial design and consulting. He has been very patient to my picky requirements and long delayed registration process. He carefully advised the best solution in balancing cost and values. We've also done first session for exterior colouring and some other amendments in head office. Justine and another lady helped me through lots detailed and quickly made other amendments I requested, very smooth process. They are always responsive to my phone calls, SMS and emails. I already referred my friend to go with them.

Our internal colours/electrical appointment was a great experience. Lots of excellent advice given. Not once was there any pressure to upgrade. The selections available we all great. Very excited to see our house completed.

You MUST GET EVERYTHING IN WRITING. We made the unfortunate mistake of trusting and taking the words of the sales person at the display home as gospel. NEGOTIATE EVERYTHING.. from the size of the door, the number of lights, power points, even blinds & tiles. DO NOT make the same MISTAKE as we did. Your house will end up costing much more to the displayed price.. If they tell you that you cannot include or make those additions until your colour appointments or internal appointments, DO NOT BELIEVE THEM because you can and everything is negotiate at the display home.
