Do you love the suburb you are currently in but have grand ideas for your home?

By utilising the old to create the new, Cassari are passionate about achieving dream renovations for our clients. Cassari is led by a team of qualified engineers, who develop and assess all aspects of each individual build first, to minimise the risks prior to moving to construction of your renovation.

As renovations normally come with unseen hiccups along the way, it pays to have a dedicated engineer along for the whole journey with you. Our client relationships are of the upmost importance to us and we ensure that we are along on the journey with our clients, at every milestone of the build.

Cassari have an impeccable history with renovations utilising mixed materials and in a remarkable feat, are the first homebuilder in WA to have won the prestigious ‘HIA Perth Home of the Year’ with a Renovation / Addition project.

We ensure that we take the time required to fully understand our clients and what their ideal home lifestyle wants to be, as there is no one design that would be able to meet all the individual needs of each type of family or individual. We strive to produce original builds for our clients that are unique to only them and their lifestyle. We believe in Individualism and Originality for our clients, not replication.

To Lorenzo and Daniel,

Pam and I would like to say a big thank you for all of your hard work and dedication to detail that has resulted in an award winning home that we can all be proud of.

From the very beginning of the project I think we all realised that this was not going to be the “normal” renovation extension, and it was going to take a special building company to overcome the daily challenges to create both the Architects and our vision of the finished product.

From early on, the feedback, consultation, and access we were provided was outstanding, and made us feel we were part of the process preventing decision making from holding the project up.

We said from the beginning we wanted a special, one off home, and would not be moving again. You have completed an ultra modern extension seamlessly joined to a circa 1900 character renovation that went on to win HIA Perth home of the Year and Australian Renovation of the Year.

This home is our pride and joy and continues to receive accolades from both our friends and industry peers whilst being our family home on a daily basis.

Well done to you and your team and we wish you every success in the future.

Happy home owners.


We have had a highly successful building experience working with Cassari builders. There were three notable features in working with Daniel and Lorenzo:

First was the good communication with all parties concerned with the build. The architect was regularly and frequently referred to; as clients (and we were hands on clients) we were involved in the process on a daily basis. Daniel was on the site nearly every day communicating with us and/or the trades people and always available by phone. Solutions were found and problems solved with good humour.

Secondly, Daniel’s selection of skilled trades people combined with constant supervision demonstrated an impressive attention to detail. Linking old with new was sometimes frustrating, but interesting and Cassari was up for the challenge.

Thirdly, the above characteristics are displayed in the quality of the build. A point commented on be visiting builders and architects.

Although small in size our renovation contained a large amount of detail, variety and complexity requiring negotiation, flexibility and adaptability to sometimes complex architectural problems.

As clients we enjoyed the whole process and are happy to recommend the Cassari team.


We have been fortunate to have had the opportunity to work with Lorenzo and his team from Cassari Group.

Lorenzo is very approachable, quick to respond to enquiries and requests, and has proved to be a skilled communicator (responsive to both the Client as well as to our Design Team). Furthermore, Cassari Group’s expert accountancy assisted in keeping both the Client and our firm abreast of all costings.

Not only does the Cassari Group conduct business in a very professional and efficient manner, but they are a pleasure to work with.

We would highly recommend Cassari Group to our clients and we hope to have the opportunity to work with Lorenzo and his team again in the future.


Daniel and Lorenzo did a fantastic job building our new house. Their attention to detail meant that we avoided costly delays, and everything went without a hitch. We would strongly recommend Cassari Group to anyone considering building or renovating


Initially we spoke to several builders before making the decision to opt for Cassari Group. We felt that although some builders had older, more established companies there was a possibility that they were more jaded and therefore set in their ways. We also liked the fact that they were the only company that talked to us as a couple; the other builders addressed the majority of the questions and enquiries to my husband. We also identified with their companies ethos and promise of ‘New Vision, Old Values’.

We consider ourselves very fortunate to have selected The Cassari Group. Daniel has been continuously approachable and understanding. It has been very clear that his goals are identical to ours in a joint desire to achieve quality workmanship and a stylish end product. He has a passion for producing the best possible outcome with minimum inconvenience. He has patiently listened to any fears or concerns and worked tirelessly to achieve a satisfactory outcome for all parties. The Cassari Group obviously take great care in their selection of tradesmen. Daniel simply will not accept anything that does not meet his extremely high standards.

We have been very fortunate in our experience with The Cassari Group. We can highly recommend Daniel and Lorenzo, they have an absolute passion for their work, they are approachable, dependable and dedicated to achieving exceptional results. We would be happy to recommend them to anyone looking for a brilliant building company and would like to thank them once again for our beautiful new home.


Cassari Group were one of several builders whom our designer suggested we ask to tender to construct our extensive renovation and extension on a weatherboard cottage over 100 years old. From the beginning, we found them to be very professional, transparent with pricing and to have attention to detail, so we chose to work with them. We were not disappointed. The building process was mostly smooth and timely…particularly when we told them we were expecting a baby and wanted to be in our house before its arrival. When issues arose that could not have been predicted due to the age of the original house, Daniel and Lorenzo made efforts to rectify them with our tight budget in mind and suggested viable solutions.

We are now in our house, just before our baby is due. It is beautiful and Daniel’s meticulous requirements are evident. We have heard many stories from friends about how difficult and stressful the building process has been, which has usually resulted in bad relations between the parties. Our experience has been the opposite and we continue to have a good relationship with Daniel and Lorenzo, who have always been good to deal with.

We would recommend building with Cassari Group because you get the whole package – professionalism, service and most importantly, a build with excellent workmanship and a beautiful home.


Our family has been blessed to have the Cassari Group undertake our home renovation; a whole house renovation with many challenges. These were dealt with by the team of Lorenzo, Daniel and Darren in a highly professional manner, always looking for ways in which they could address our needs. The team displayed excellent communication, enthusiasm and a willingness to help. Their energy level was outstanding and their work ethic and attention to detail in all aspects of the job was excellent. The contractors also displayed similar qualities as their builder, which has helped make the whole process a good experience.

There have been many recent renovations in our street, but the Cassari Group receives the gong for the fastest and most efficient renovation – taking just over 6 months.

The result is our family has a beautiful new home which we love.

We would highly recommend the Cassari Group to anyone looking for a professional builder to renovate, or build your new home.

Thanks guys!


Thank you Lorenzo and Daniel. We have been living in our new home for the last few months and absolutely love it! When we first looked into building a house, we were warned how stressful the process could be. Indeed there were certain stages of the build where this was the case, but your expertise and professionalism ensured that our worries were short-lived. In fact, we found the process of building both exciting and fun and were always made fully aware of the different stages of the build through the constant communication that you had with us.

From the initial designs, demolition, build and finishes we are extremely grateful for all of the excellent advice that we received from you all. You were prompt to respond to our questions and reacted quickly to any action that needed to be taken. Our questions were always dealt with professionally and respectfully, no matter how menial they seemed.

Building a home with Cassari has been exceptional. Not only do we have the house of our dreams, but we have also developed a lifetime friendship. The journey has been incredible. Being part of the building process and having the ability to have input has ensured that the end result is not just another new house but an outstanding home that suits our needs.

Should our needs change in the future….we would have no hesitation in starting the journey with Cassari again.

A sincere thank you from Paul and Gabrielle Brennan.


I can’t recommend Cassari builders highly enough. Lorenzo and Daniel have been meticulous in both their project management and design construction. We did our comprehensive extension while we were living overseas which could have been tricky, but the fantastic outcome is testament to their performance during that time. Their customer service/ client relationship has been a delight, working with us to solve any issues that arose. I would, and already have recommended to friends. We truly ended up with the house we dreamed of.


“Lorenzo and his crew from Cassari Group have been excellent. They’ve been incredibly flexible with changes we’ve wanted to make and have chased up some of the supplies we needed from all over Australia.

The workmanship has been of a high standard and Lorenzo or Daniel have rung us to tell us if they’re not happy with something rather than us having to chase them up. They even assisted us with finding landscapers and other tradesmen outside of the scope of their job. I’d be happy to recommend them to anyone considering using them for any building project.

Thanks guys!”
