Home Plus One is your expert granny flat builder and designer in St George and Kogarah.


We Make Things Simple

We know how stressful a construction project on your property can be. Our service has been designed to make the process as easy as possible for our clients. We’ll guide you through the consultation and design process, sort the planning paperwork for you and then complete the construction on time and on budget.


We Only Do Granny Flats

At Home Plus One, our business is focused solely on designing and building stylish, modern granny flats and nothing else. We already know the local planning laws that could affect your build, the common issues experienced in construction, and what clients are looking for from their new space. Because of our specialism in this area, we can anticipate your needs and have a showroom full of granny flat fixtures and fittings ready for you to fit out your space beautifully.



We Can Inspire You

The Home Plus One architectural team has designed 5 different ready-to-build granny flat models to suit your style, property and space needs. Whether you’re planning a modern or traditional look; timber or brickwork; sloped or flat roof – we have designs to fit your style and exceed your expectations of what a granny flat can be.


We Are Experts

Home Plus One is a team of architects, builders and tradies all chosen for their exceptional level of knowledge and skill. When you choose Home Plus One for your next project, you’ll be in safe hands from the first design consultation right through to the post-construction inspection.
