Get two homes from one block. Modular dual occupancy and secondary dwellings built fast, for rental income, multigenerational living, or both. Built in our factory, installed in days.
Dual occupancy is one of the smartest ways to get more from a block in NSW. Whether you want a second income, room for extended family, or a home to grow into and rent out later, building a second dwelling adds real value. Hi-Tech Modular Homes builds the homes and secondary dwellings that make dual living work, with a fixed price and minimal disruption to your land.
Dual occupancy means two dwellings on one lot. In NSW this usually takes one of two forms: a detached dual occupancy (two separate homes), or a primary home with a secondary dwelling, commonly called a granny flat. The right path depends on your block, your zoning and your goal. The rules and minimum lot sizes vary by council, so the first step is always to check what your site allows.
Up to 60 square metres, often approved fast through the CDC pathway on blocks of 450 square metres or more. Ideal for family or a single rental.
Two full homes, more income and flexibility, but subject to your council's lot size and zoning rules. We build both homes modular.
Send us your address and goal and we will tell you what your block supports and what it would cost.
Putting a second dwelling on an occupied block is where modular really shines. Your home is built off site in about 8 weeks, then craned in and installed in roughly 2 days, so the existing household lives through days of work rather than months. Less mess, less noise, and a fixed price. See how it works on our process page.
A second dwelling commonly rents for about $450 to $650 per week in Sydney depending on size and location, and a well-planned dual occupancy can add significant value to the property. We break down realistic returns in our granny flat investment guide and rental income guide. This is general information, not financial advice, so check your situation with your accountant.
A secondary dwelling can often be approved through complying development (CDC) in about 10 to 20 business days on a qualifying block. A detached dual occupancy more often needs a development application with your council, since lot size and zoning rules apply. We help you understand the pathway for your site. See our plain-English guide to CDC versus DA approval.
It depends on your block size and zoning. A secondary dwelling is possible on most residential blocks of 450 square metres or more. A detached dual occupancy depends on your council's rules. We will check your site.
A compliant secondary dwelling can be rented to anyone in NSW. Detached dual occupancy rental depends on the approval. We will confirm what applies.
Allow approval time, about 8 weeks for the factory build, and roughly 2 days for installation, plus site preparation.
Send us your address and what you want to achieve, and we will tell you what your block supports and what it would cost.
