Take your home to the next level

Summit's game-changing modular building method can take your home improvements to an amazing new level in no time. 

We can build your second storey addition in our purpose-built, all weather proof factory so you're able to continue living in your home as we complete the renovation. 

Once complete, the extension is simply craned into position and secured to your existing home and is free for you to enjoy in a matter of weeks.

Move up without moving out

Meet Andrew and Chatarina. Having recently added a second storey extension to their family home, Andrew and Chatarina are now enjoying the extra space thanks to Summit Renovations.

With a stunning staircase that leads to a new master bedroom, ensuite, lounge room and study, the extension has left Andrew and Chatarina with the ultimate parents' retreat.

Hear what they have to say about their renovation journey with Summit.

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.

  • Step 1 out of 3

    Construction

    Comfortably live in your home while we construct your upper floor extension in our purpose built, all-weather facility at our Myaree headquarters. We manufacture our steel frames in our factory which can operate 24 hours a day, and this controlled environment not only ensures the frames are built to exact specifications, but helps reduce the chance of delays.

  • Step 2 out of 3

    Delivery

    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.

  • Step 3 out of 3

    Completion

    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.

Testimonials

  • We chose Summit because of their reputation and their prompt communication. Our renovation is now complete and we've only been in the house for a month and it has totally exceeded our expectations. I think I could sit in my pantry instead of watching Netflix as it is absolutely stunning. Deb Pearcey and I were on the same wavelength - she turned my ideas into a stylish reality. We pinch ourselves at how a 25 year old house looks so incredibly different. Thank you Summit.

    James & Tania
  • Whilst some builders are going under, it's easy to see why Summit is thriving. The people who work for them on site clearly love what they do as they have been very professional and respectful throughout our build and are very proud of their work. Our site supervisor Jason has done a great job during these demanding times and we are thankful to everyone involved.

    Ken & Rebeccar
  • From first contact and throughout the Design phase, our Consultant Charlie was exceptional. He brought a depth of knowledge of older homes, personal experiences, and the ability to listen very closely to our vision and design brief. His experience and knowledge, for us, who had never renovated before, assisted us greatly through the design/selection phase.
