We highly recommend Extensions Unlimited to anyone looking at either a big or small extension.

The entire process from the initial enquiry with Sandy, design stage with Ted and construction phase with Nick was easy yet clear and detailed.

We couldn't speak highly enough of Nick and his construction team. They are fantastic people, reliable and trustworthy. Jackson and Nicko were fantastic.

Throughout the build we were consistently updated by Nick on what was happening and when. If there was a change in schedule it was communicated promptly and we always knew what was happening and when.

5 stars to all of the team at Extensions Unlimited.

We have had a wonderful experience with this company, starting with Spiro, and through out the entire build with the amazing team of Brett and his Team ( special mention to Jack). They always kept our comfort and safety in mind the whole time, even our fur babies and grown up kids were always kept comfortable and safe throughout the whole building period. We undertook a huge job with this company and essentially rebuilt our whole home and the final product is a fantastic custom home exactly as we imagined it. Thank you for making our dreams a reality and being so professional and thorough with your work. We can thoroughly recommend this team to anyone who is planning any sized renovation/extension.

Thanks

Thanks everyone, we couldn't be happier with the result! Our new extension is life changing and looks like its always been there. From start to finish the team were professional, available and incredibly patient (there were many questions!).
The build itself moved quickly and we didn't even need to move out.
We love our new home and highly recommend Extensions Unlimited.

We highly recommend Extensions Unlimited for their phenomenal work on our project. Our project manager Brett kept us informed of the progress throughout the build and his team were a pleasure to deal with on site. What sounded like a huge job to us was completed seamlessly and ahead of time. Penni, in the office was most attentive to our needs, no request was too hard. Thanks Extensions Unlimited.
Chris Burridge
Great building experience. They were able to design an extension to exactly what we were after.
Charles Juhasz
A huge thank you to the Extensions Unlimited team for their exceptional work on our project! From the start, Ted was incredibly patient and enthusiastic throughout the design process, ensuring every detail aligned with our vision. Once construction began, Emilio’s commitment and leadership made all the difference—his dedication to achieving our goals was evident in every step. The entire team was professional, attentive, and a pleasure to work with. We couldn’t be happier with the result and highly recommend Extensions Unlimited to anyone looking for a seamless and high-quality renovation experience!
Thank you!

We had a great experience with extensions unlimited. We used them, as friends in Hampton and Cheltenham had found them good to work with for their projects, and it was the same for us. We added on a floor upstairs (2 beds, bathroom, rumpus) and moved some walls downstairs. The job was completed on time (about 6m all in), the quality was good, and Brett (the project manager) and the rest of the team were good to deal with. When we hit any issues, we talked through the options together and worked out a plan. And they helped rescue our cat when it got stuck in the sub floor.
Angelo Perera
Extensions Unlimited did an absolutely fantastic job with our recent extension! From the initial design consultation to the final touches, their team was professional, knowledgeable, and a pleasure to work with.

The designer Barry was incredibly prepared and presented us with a solution that perfectly matched our vision. Throughout the entire project, the team kept us informed and involved every step of the way. Jack, our project manager, was always prompt and helpful in answering our questions.

The project was completed on time and within budget, and we couldn't be happier with the results. We highly recommend Extensions Unlimited to anyone considering a home extension

Why choose a 1st floor addition

Why choose a 1st floor addition

When adding a second storey to your home is not desired or an option, simply extending or adding a room (or two) to your ground floor can be the perfect solution.

A first floor addition is a useful option to increase shared living spaces for growing families or multi-generational living arrangements, add a dedicated home office, or totally rearrange your floor plan to maximise entertaining to get the most out of your backyard. Our in house design team consults on your specific needs to provide single floor addition plans that harmonise with your existing dwelling, that enhance your life through moments life is made of.

Extensions Unlimited has been creating extra space for Melbourne families for over 30 years!

Cost of a single floor extension

Cost of a single floor extension

What can affect the cost of any addition on your property are factors like property access, the presence of trees (either on your property or adjacent neighbours), the condition of the soil, and the slope of the land, which can affect the ease of excavation.

An expert house addition company like Extensions Unlimited is a great choice for your first floor addition because our communication is impeccable, so there is no surprise extra costs during construction.
