What our Clients say...

See what some of our clients have said about their experience with XL Built home extension builders

XL Built took the time to truly understand our vision and delivered a home that exceeded our expectations in both design and quality. They made the whole process stress-free with clear communication and no unexpected costs. We highly recommend XL Built

Natalie P

Second Storey Extension

XL Built exceeded our expectations with an on-time and on-budget renovation of our 100-year-old single fronted terrace house in Richmond.

If we ever build again, XL Built will be our first choice

Andrew R

Ground floor extension

We had a fantastic experience renovating and extending our house in Hawthorn with XL Built. Luke and his team were responsive, efficient and always going above and beyond to make sure we were happy. The quality of both the new extension and the works to the original 120 year old cottage is excellent.

We couldn't be happier with the result and recommend XL Built.

Margaret G

Single Storey extension

XL Built were impressive from our first interaction through to the last. Unlike others, Luke spent the time to understand our council’s construction requirements and planning permit requirements even before we met so we could get a good idea of total build duration. He also came prepared with some great suggestions in order to maximise opportunity within budget.

Would highly recommend XL Built!!

Stacey S

Second Storey extension

Our experience with the XL Built team was outstanding. Their professionalism and quality was well above all expectations. I went into the renovation process with a lot of skepticism after hearing of many horror stories. XL Built have well and truly changed my mind and I would recommend and reuse the team for any future work.

Thanks to Luke and his Trades for creating beautiful spaces for our family.

Michael C

Extension and renovation

Luke and his team picked up the plans done by a draftsman to execute our renovation vision with patience, care and attention to detail.

We couldn't be happier with the result. Great oversight from Luke, professional trades who took real pride in their work (special callout to the tiler) and an amazing product at the end.

Would definitely recommend XL Built for anybody considering a renovation or extension.

Richard S

Extension and renovation

We went through an intense process looking for a home extension builder and went with XL Built due to their sheer professionalism and we weren’t let down.

As we had undertaken a previous renovation not long before, XL Built was able to preserve and reuse most of our old items…Never overpromised, were super patient as we kept changing things around and in fact finished before schedule and left everything very clean.

Highly recommend them as they have given us a beautiful home.

Parvana Wali

Extension and renovation

We've been back home for a month now, and I just love our 'new' home. We all have some much needed space, not to mention the extra storage!

From start to finish, we were updated at every stage, and we appreciated all the hard work of the XL Built team. The new bathrooms are gorgeous, and the second storey is brilliant.

Thank you again to Luke and the team for taking our ideas, and turning them into an affordable reality.
