Two Storey Additions

Reach new heights without moving out.

A Second Storey Addition made easy

With more than 40 years’ experience, Summit's renovation team is renowned for award-winning, custom designed, seamless second storey extensions which will give your home a new lease on life.

Our game-changing building processes take your home to an amazing new level, super-fast.

We give you the option to build your second storey extension either via traditional on-site build or in our purpose-built, all weather proof factory located in Myaree. The choice is yours. 

Whether you are looking to extend and add a parents' retreat, a children's wing or capitalise on those tree top, city or river views, Summit can custom design your extension to seamlessly blend into your existing home, as if it's always been there.

The only way is up

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

We can build your second storey extension 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.

Listen to our Building Manager run through all the benefits of building a second storey addition 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


    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


    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


    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.
