what we do


We can work closely with you and your architect to build your dream home. We will always work towards delivering your project in an efficient and timely manner while maintaining a focus on quality workmanship and communication with you throughout the project to ensure nothing is overlooked and you will be left with a new home you’ll be able to enjoy for many years to come.


Renovations and additions are a different ball game to new builds and they offer up a new set of challenges. At HBS we have vast experience in this area of building and no challenge is too big for us to handle, whether its adding a first floor or a split level addition out the back or even working on a heritage building we can adapt and work with any design on any existing style of house.

featured projects

New Build – Country Style Cottage – Galston

THE BRIEF: To construct an architectural designed home with country/rustic charm, along with having an improved thermal efficiency and use of Low VOC products.
THE RESULT: The project was completed in June 2019 slightly behind schedule, however the clients love the detail in the finishes provided and regardless of the delays are still happy with the finished product. There was an emphasis put on the use of zero or low VOC products and alternative glues and sealants were used along with some natural paints sourced from a supplier in Byron Bay.

why choose us


We pride ourselves in our level of communication with each client, providing access to our build schedules and daily job logs as the work progresses through our project management software CoConstruct, as we believe you deserve to know what’s going on with your own home! This open book approach builds trust and gives the client a sense of involvement and security without having to step foot onsite!



We have found one of the best ways to impress anyone of our clients is to simply be reliable (and clean up!) This means when we say we will deliver, we do so on time and on budget. We can achieve this by using the experience of our direct team and also network of reliable contractors, and most importantly communication. If there are any changes or unexpected variations along the way we will keep you well informed so there are no nasty surprises at the end of the project.

3. Sustainable/Environmental Building

We are becoming more environmentally aware with everything we do and are always looking for ways to improve this aspect of building. If this is important to you also then we can look further at using products like Low-0 VOC adhesives, paints and building boards, along with using sustainable products and reducing waste on site. We are currently learning more about using Hemp products in construction, so we look forward to updating everyone as we learn more about this when we build our first house using Hempcrete scheduled for completion early in 2021!

4. Fully Insured

We are fully insured for all building works, public liability, and workers compensation so you can rest assured if anything does happen it will be taken care of. Also if your project is over the value of 20k then we will obtain a HBCF policy specific to your project as is required in NSW, which adds extra protection for you in the event we aren’t able to uphold our contractual obligations with you directly.

5. Industry Support and Training

We are proud members of HIA and MBA, and can use this network for any additional support whether its technical or otherwise and this also helps us keep up to date with ever-changing building regulations. The team members at HBS benefit also, with access to educational and professional development courses that are often put on by these associations.


We couldn’t be happier with our decision to use Rob and his team at Hainsworth Building Solutions. From the get-go, Rob impressed us. He was extremely helpful and invested a lot of energy into the initial stages of quoting and finalising the contract, taking the time to really listen to what we were after.
Throughout the build, Rob and his team continued to impress us with their professionalism. Nothing was ever a problem and if met with any challenges, Rob would take the time to find a solution and talk us through it. He is an excellent communicator and kept us up to date with the project.
As the project was our own design, being involved in the build was also very important to us. Rob was a fantastic collaborator and worked closely with us to deliver an amazing result, bringing our vision to life and building us our dream home! We are extremely grateful and couldn’t recommend him highly enough.
