TG Building is owned and operated by builder Tony Gronowski, offering custom home-building business in the Hills District. We service the whole of the north-west Sydney region, providing a reliable and personal service. Whether you are looking to build your dream home, renovate, extend, build a granny flat, deck or pergola, we strive to get the job completed on time, within budget and to the highest standard of workmanship.

We believe in doing quality work - every time. Our commitment to the highest standards in building mean that you will be proud of everything in your new home or extension.

We can help with design and building approvals, full construction, right up to the necessary finishing touches.
Services
We pride ourselves on producing quality work to ensure a stress-free build and a beautiful end result in every way. With demand rising for multi-generational housing and rental accommodation, we can help you turn your home into an income-generating asset. Looking to extend your home, add a second storey, or even just improve what you already have?
As experienced builders and carpenters, we work closely with our clients throughout the building process to ensure a stress-free build. We consider the relationship to be a partnership, bringing our expertise to create the level of quality you expect from our small and enthusiastic business. Working on projects large and small, we provide an attention to detail on all our building sites to ensure that you get the result you want.
I strongly recommend Tony and his team. He has just finished our renovations and we couldn't be happier. His work is top notch, he was very organised, and he is full of practical advice. And a special mention regarding variations - we decided to make some small variations during the renovation, and Tony's pricing was very fair and reasonable.
It's important to decide how much you can spend right from the start, because that will determine other important issues about your new home, such as the size, the type of materials used and the fittings you are looking to install. Before we start working with you on a design, it's good to decide what are your must-haves, so you can be informed of the financial elements of the build and any compromises you might need to make.

TG Building & Carpentry did a major renovation work for our single storey house recently, which included a complete makeover of the kitchen, laundry, bathroom, new roof, windows, flooring, lightings, skylights, remodel internal structure, back extension, external rendering, cladding and painting.
It is not easy to find an honest reliable builder that can accommodate our requirements and needs.
However, we decided to give Tony a chance to take on this challenging project which was not an easy one.
Throughout the process Tony was cooperative and willing to listen to our needs. He is flexible and

We have recently had a second storey addition to our home in Baulkham Hills. After our very 1st meeting with Tony we were confident we had found the right builder for the job! I cannot speak highly enough of the professional manner in which Tony displayed himself throughout the entire process, we can honestly say there was not 1 hick up! All… tradesmen were punctual, courteous and the workmanship was faultless. Tony we cannot thank you enough for the beautiful home you have made possible. I highly recommend the service's of TG Building and Carpentry.

We commissioned Tony and his team for a garage conversion and laundry reno. The team was responsive and finished the build to a high standard. We were very pleased with the end result and can't recommend TG Building & Carpentry highly enough!

Excellent work. Great ideas. Tony took the pressure off me in all aspects of the build. Very easy to deal with. Finished ahead of schedule & on budget.

Tony was very reliable and professional. His workmanship was great and completed the job on time. He kept us up to date on progression and gave useful suggestions on our renovation.
We would definitely call on him again when we have other reno jobs to do.
