I am so impressed with this wonderful company “Frame Steel” I really appreciate their expertise , professionalism, patience, advice and understanding. Our granny flat took quite a while to complete and I’m sure I annoyed Cassi with lots of stupid questions etc but she was always lovely and very helpful . Great sense of humour too! Thank you to all concerned and I would recommend your company to anybody. A superior company ! Julie Kelly Pinbarren Queensland

Amazing experience from start to finish. Cassi in the office was quick to organise exactly what we asked for and helped us achieve exactly the granny flat we wanted by way of adjustments to the plan. Delivery was on time and all the staff were amazing. I knew the building industry was having trouble and half expected huge delays but nope... all sent withing a few short months. Everything stated in the inclusions was provided, even some extra's by way of bolts and screws etc. I like how they provide you with all the details of exactly what you are getting first so that you can factor in what is needed in your budget. We have certainly saved a lot of money doing our own Owner-builder and we were able to afford a larger than usual place for our family members during the rental crisis. I would definitely recommend and use them again if I needed to build. A pic of the start of our build so you can see the frames. Thanks Frame Steel! UPDATE: near finishing pics added. This place is huge, rooms are very spacious. Came out much better than expected!

From the start Frame Steel have been so accommodating and helpful. We made a completely customised plan and Cassi was able to help us with dimensions and suggest things we should and shouldn’t do. The price was very competitive and putting it together has been very doable for non builders.

First time buying a kit home, process was easy and I made some changes along the way which were accommodated. Will not hesitate to buy another one in the future.

This was the second time we bought from Frame Steel to build a granny flat - The Cabin - after a great experience the first time. Again, it was a the best decision, because the frame was delivered on time and the building was up in quick time - our builder said it is a really good kit to work with. The building looks great and the layout turned out really well. with an adjustment we made to convert the laundry enclosure into a pantry and included the laundry in the bathroom as there was plenty of space there. A very comfortable dwelling at the end of it all. The team at Frame Steel are easy to deal with and very helpful.

Our Popular Designs

Thinking about building a kit home?

cost effective

Kit homes & kit granny flats are quickly becoming an Australian favourite. With the building industry experiencing increased demand across the board, the price for traditional builds is becoming more unaffordable. The benefit to building a kit home is that your materials are a fixed cost from the time you place your order, until the materials are delivered.

easy assembly

Contrary to popular belief, building your own house can be quite easy. At Frame Steel, we manufacture all wall frames & roof trusses, so they’re ready to stand on site. All kits are supplied with comprehensive, easy to read plans & instructions to make sure your build goes as smoothly as possible. And because all kits are manufactured in house, we’re available for phone support during standard business hours.

full range of colours

Gone are the days of limited colour choices. All roofing, gutters, corrugated wall cladding & window frames are available in the full range of standard colours. We offer 22 different colours for roof, gutters & corrugated wall cladding, & 7 colours for window frames.

Custom home design

Building a custom home can be a costly exercise, and not always a pleasant one. That’s why at Frame Steel, we believe in choice! We encourage you to change our designs, because if you’re not happy with your home, we’re not happy. Our designs can be changed free of charge (moving/removing walls & windows/doors), and we’re more than happy to provide complete custom designed kits if you want to get creative.

work at your own pace

Owner building is extremely rewarding. It also gives you the flexibility to complete stages of your build at your own pace and/or when your budget allows. Being in control of the process is a much more enjoyable experience than chasing trades for completion dates as is the case with a traditional home build.

why frame steel?

Frame Steel is a local, family-owned business in Yatala QLD. All our framing is rolled & manufactured in our Yatala factory & shipped out directly from us. We use all local suppliers for our windows, doors, roofing & cladding, so you’re getting the best quality products, at the most affordable prices. With over 10 years in the kit home & kit granny flat industry, we offer comprehensive knowledge & friendly service throughout your build.
