We recently completed the renovation of our home in Beecroft with Tony and his team from Boronia Building.

It was quite an extensive renovation and we are extremely pleased with the result. The one thing that strikes you about Tony is the passion he has for what he does. He treated our renovation as if it was his own wanting to make sure it was of the highest quality.


Tony and his Boronia team were fantastic right through the project from the initial design discussions of renovation through to job completion.

So much so, we are now talking to Tony about the next project. The Boronia building team were professional, reliable and their finished work – first class.


My wife and I would like to thank Boronia building for our recent renovation in Epping. We used Boronia building after doing extensive research with a number of builders.

We have a 100 year old house that we wanted to keep the older federation look but renovate the inside to fit in with a more current open plan family living lifestyle.
