2019 HIA-CSR

Castle Construction Tasmania was the winner of the 2019 HIA Custom Built Home up to $500,000.

Designed as a modern but functional home, the build involved the removal of a previous dwelling and the creation of a new home that blended seamlessly into the challenging split level site.

The choice is yours.

We have an experienced housing design draftsman as part of our design team who will meet with you on site and discuss all aspects you wish to achieve for your new home or addition to make your home vision become a reality.


We understand the complexity of building your dream home or renovation and as such have a highly competent and well trained team that can provide you with professional advice, personal service and quality craftsmanship you need to ensure a seamless building experience for you and your family.

Over the last 30 years we had consistently delivered quality outcomes for our clients.

Our Experienced Team

We started out as a partnership in 1986 called B & C Castle Carpentry.  After gaining a reputation as builders we formed our company Castle Construction (TAS) Pty Ltd in 1990.

Since then we have gone from strength to strength. Castle Construction (TAS) Pty Ltd is a fourth generation business that specialises in custom homes, renovations and extensions on the East Coast and South East districts of Tasmania.

Our friendly and highly qualified East Coast Tasmanian building and construction team are dedicated to providing you with a quality and memorable building experience. 



Brett initially did his apprentice with John Castle.  He then transferred after 12 months of carpentry to boat building under the guidance of David Jones.  He soon discovered that his passion was in working with timber and became a qualified builder. For the last 30 years he has been building quality homes up and down the East Coast of Tasmania.



I started school at Orford and finished my high school years in Hobart.  I worked alongside Brett as an apprenticeship and have completed Certificate IV in carpentry. I now have the pleasure of running Castle Constructions.



Carol is responsible for all aspects of the bookkeeping of our business, from quoting thru to invoicing.  She plays a very important part in the day to day running of Castle Construction.

It is an honour to provide a testimonial for Castle Constructions. During the design phase for our new home in Little Swanport we met with Brett to understand his availability, capability and integrity as we did with some other builders.  What we liked about Brett was his willingness to help by providing us with some indicative pricing and that he said that his reputation, or integrity, was very important to him and that his projects finish on time and are finished to a good standard.  When our design was finished Brett provided us with a fixed price quotation and a commitment to finish the project by an agreed date and it was on that basis that we contracted the project to Castle Constructions.  

From the moment the construction started  right through to its completion we never doubted that the project would be finished on time. We visited site regularly and so got to see the cohesiveness of all of the many different trades working together. Castle Constructions capability doesn’t not just rest with Brett and Carol, they have a very capable team of staff and subcontractors seamlessly working together ensuring the delivery time is met and that the finishing standards are very high. Our house is somewhat unique and Castle Construction’s team have been able to meet the challenge and deliver a result that has exceeded our expectations. 

We are very grateful to Brett, Carol, Jason and all of the staff and subcontractors who worked on our home. To finish our home on time and to such a high standard is a testimony to the integrity and commitment of all involved.  We wholeheartedly recommend this team to anyone who wants to be in good hands from start to finish.

We had our plans drawn up and went out to tender for the construction of our new house at Swansea.

Various tenders were received and we met with Brett and Carol Castle at Triabunna to discuss our plans.

We liked Brett and Carol and got on very well with them and discussed our plans and what our families were doing.

After consultation with our designer we awarded the contract to Castle Constructions. We were living in Launceston during construction and we made numerous visits to Swansea to discuss progress. Brett was very helpful and made suggestions along the way to improve the end result.

The team on the construction were well supervised and we knew that Brett had an excellent reputation as a reliable and capable builder.

There are a number of dwellings in the Swansea district which attest to this. We are happy with our completed house and we still maintain contact with Brett and Carol.

I  know that we were contacted by a prospective new client of Brett’s during our construction and that based upon our experience they engaged Castle Constructions.

“We cannot recommend Castle Construction highly enough. From the initial quotation meeting with Brett it was obvious that he had a remarkable knowledge of the local area. Brett fully understood and explained to us the rational for the substantial footing work stipulated by the engineers which other out-of-town builders quoting on the build were quick to dismiss as overkill. This immediately gave us confidence in Castle Construction.

Throughout the entire build the team at Castle Construction were fantastic to deal with. Jason and his crew are easy going and approachable. They were more than happy to accommodate the multitude of changes or additions that we made along the way. We really appreciated the fact that Jason would call and ask us our opinion on various
options or suggest improvements on particular aspects during the build rather than just take the simple hard line ‘per the plan’ approach. Jason would then follow-up to obtain our feedback on what we thought of the progress at various stages and to see if we were happy with the way things were going.

As this build was for our holiday house (and performed partly during Covid lockdown) we were limited primarily to weekends to view the progress and we were amazed at the đevelopment made week to week. Jason mentioned to us early on that if he was getting his own house built that he would want to see something substantial develop each
week and he certainly achieved that with our build.
During the build Brett, Carol and Jason maintained great communication with us. They were upfront and transparent with any additional costs that were associated with changes or alterations that we requested.

Castle Construction are professional in everything they do. They did not cut corners, they stuck to their quotation and there were no unexpected extras other than what we openly discussed and agreed to along the way.

Our build was hassle free and an absolute pleasure. The quality of our finished home and the amazed reaction and outstanding feedback from our guests is testament to the knowledge, workmanship and attention to detail of the skilled Castle Construction tradesmen.

Our family will be forever thankful for the beautiful home Castle Construction have created for us. We highly recommend Castle Construction for any new build or renovation on the East Coast.”
