Modular and transportable granny flats designed, approved and installed across Sydney and NSW by a builder with over 30 years on the tools. Less mess, a fixed price, and your backyard back in days.
A granny flat is one of the smartest things you can add to a Sydney property. It gives your family room to grow, it can bring in a strong weekly rent, and it adds real value to your block without you having to sell up and move. Hi-Tech Modular Homes makes the whole process simple, from first enquiry to the day you get the keys.
Sydney blocks are valuable and space is tight, so a well built second dwelling earns its keep. Families use them for ageing parents who want their own front door, for adult kids saving for a place of their own, and for a home office that is properly separate from the house. Investors build them for the rent, which in Sydney commonly sits between about $450 and $650 per week depending on size, finish and location.
Because our homes are built in the factory and delivered finished, your backyard is only a work site for a couple of days rather than several months. That matters a lot on a suburban block where access and neighbours are a real consideration.
Every design is built to suit the 60 square metre limit for a secondary dwelling while still feeling like a proper home.
For a full breakdown, see our granny flat cost Sydney guide and the detail on site costs like sewer, slope and services.
Most residential blocks of 450m² or more qualify for the fast CDC pathway. We confirm yours.
A private certifier signs off the CDC, usually in about 10 to 20 business days, with no full council DA.
We build in the factory in about 8 weeks, then install on site in roughly 2 days.
We explain the pathways in our guide to CDC versus DA approval, and you can check the minimum block size rules for Sydney before you start.
With factories at Bringelly and Elong Elong, delivery is quick and clean to most suburbs.
Read how it comes together on our process page, or the common questions on our FAQ page.
The maximum internal floor area for a secondary dwelling is 60 square metres under the NSW Housing SEPP. Covered decks, verandahs and carports sit outside that figure, so you can still add outdoor living space.
Allow roughly 10 to 20 business days for CDC approval, about 8 weeks for the factory build, and around 2 days for installation, plus site preparation.
Yes. A compliant secondary dwelling can be rented to anyone in NSW. We cover the numbers in our granny flat rental income guide.
