How GM Building and Renovations Can Help You


Extensions add size, space and value to your home by either enlarging its footprint or adding another storey. And with GM Building and Renovations, you don’t even have to move out! Wherever possible, we renovate in carefully-planned stages so you can continue living in your home and won’t waste money renting elsewhere. We’ll work with existing plans or bring our own draftsman on board to design the home you’ve always wanted, in the neighbourhood you know and love. #improvedontmove


By simply changing your home’s layout, GM Building and Renovations can increase both your living space and your home’s value. Removing a load-bearing wall is a cost-effective way to convert to open-plan living. Even shifting doors and windows can improve your home’s ‘flow’. We provide engineered solutions to support your roof structure and ensure council requirements are met.


The kitchen is the heart of any home and has the greatest impact on resale value. GM Building and Renovations can create the kitchen of your dreams, which will also prove to be a smart investment. From installing modern cabinetry to enhancing functionality with an island benchtop, we have ideas and options to suit every budget.


A bathroom with dated fixtures and fittings can date an entire house. Bathroom renovations by GM Building and Renovations breathe new life into your home. Say goodbye to loose tiles, leaking tapware and dingy décor and see your space transform as we install modern features like frameless shower screens, wall niches and heated towel rails.  Your new bathroom will be fresh, functional, easier to clean and give you the ambiance of a luxury spa in your very own home.

    “We found Robbie a pleasure to work with. Reasonably priced and always cleaned up at the end of the day. Nothing was too much for them or their team. The goal for us was to remove 1.5 meters from the house front to back to make way for a driveway access to the back yard (future subdivision). We created a new ensuite, walk in robe, bathroom, office and laundry. Very professional and willing to listen and talk about our project in detail. It was good to be on the same page. I would (and have) recommended GM Building and Renovation to others. Am happy to engage their services for future projects.”

    “Very happy with the overall job that has been delivered by Rob, knocking down a wall in my house. I thought I would never be able to remove the wall that separated my dining and living room, because it was a load bearing wall, but hey, Rob can do it. He can do it safely and the price is very reasonable. Now my house looks bigger and nicer from the inside. His customer service is very good as well, a very polite man and easy to talk to discuss what you need. In the end he also cleaned up, even mopped my house after he finished with his job! Highly recommended and definitely will use him again for future jobs”

    “Used GM Buidling for removal of a load bearing wall and another minor wall to make way for a kitchen renovation. Communication from start to finish was excellent. They also removed some kitchen units, floor and wall tiles. We were so impressed with his workmanship, thoroughness (down to every last detail including repairing cornice) and how clean he left our house. Price was very reasonable and he also gave us contacts/quotes for other trades such as sparky and plumber. Highly recommended!”
