Building your two storey extension

When it comes to constructing your second storey addition, Summit Renovations can either build your addition on-site or in our all-weather factory in Myaree. Lets take a look to see what option is best for you.

On-site build
Modular build

How your second storey extension is constructed often depends on the environmental elements surrounding your home. First we assess the location and factor in nearby power lines, narrow streets and existing trees which could limit your options when it comes to a modular build. Other factors to consider are your budget, as this can determine your choice of construction, as well as your living arrangements. Summit’s reputation for quality and building excellence means you’ll receive the same high-end product whether you build on-site or have a modular extension.

Summit offers a unique solution to transforming your home with a second storey addition. Our new factory in Canning Vale employs West Australians to build our modular homes, and allows construction of your home without disrupting your daily routine. You can continue living in your home during the construction process, knowing that your safety and comfort are our top priority. Once the extension is complete, our expert team carefully crane it in and secure it onto your existing home.

With our innovative approach, we take your home to new heights, super fast.

Our exclusive modular addition process

If you choose to utilise our innovative construction technology, your second storey addition will be built in our all weather proof factory. By combining the strength of Australian Truecore engineered steel by Bluescope, with the advanced thermal-properties of MasterWall, we offer a stronger, superior finish. The completed extension is then simply craned into position and secured to your existing home. From there your staircase is installed and all services connected, so you’re free to enjoy the extra space within weeks.


Comfortably live in your home while we construct your upper floor extension in our factory located in Canning Vale. We manufacture our TrueCore steel frames at our Myaree headquarters and construct the modules at Canning Vale. This controlled environment not only ensures the frames are built to exact specifications, but helps reduce the chance of delays.

Your second storey extension is delivered directly to your door and craned into place in just a few short hours. The key advantage of this method of building is that you can stay living in your home whilst the upper-storey module is being constructed offsite. This is a real financial benefit to homeowners, particularly if they need to rent another property whilst they’re waiting for their home renovation to finish.

It’s pretty amazing to watch a home transform over such a short period of time because as a homeowner, you can literally leave for work in the morning and come back that evening with a second story all framed up! Then once your staircase and service connections are finished, in a matter of weeks your new home extension is complete.
