What people are saying about us

We love what we do — and so do our clients.

Marco Polo Foods  |  Malaga


Peter, we would like to give a big thank you for the completion of our new warehouse and offices in Western Australia. As we are based in Sydney, we were not sure how the process of building in another state would go. You made the process very smooth and completed the project ahead of schedule which was a bonus for us.

We have worked with other builders in the past and working with your company was certainly a very different and pleasurable experience. You made the building process uncomplicated and we are especially grateful that you coordinated our whole project from beginning to end, which included amalgamating our blocks, design, and construction. You kept us constantly updated and your progress videos were much appreciated.

You have been a true pleasure to work with. We are happy to recommend your company to anyone who wants top quality work at a very fair price.

Corpus Christi Church  |  Mosman Park


Peter has done enormous work on our Church buildings, which involve heritage conservations and a degree of adaptation of heritage restorations. Over the last six years, he has also demonstrated his extensive experience on all aspects of construction and building works, including surveying and tender estimation, through to efficiently managing the building projects.

Peter is a great team member and makes a genuine contribution to the process of planning projects and resolving issues as they arise when work is in progress. He is very generous and helps to make the construction process a pleasure.

I highly recommend Peter and Colli Constructions as a competent builder and construction director.

Maptco Holdings  |  Malaga


I would like to take this opportunity to thank you for the work completed at our new warehouse. Your quality of work was top-notch and your familiarity with building codes facilitated a smooth and hassle-free process when it came to building permits and inspections.

Having effective communication skills, you kept us closely informed of work schedules, delivery, and projected completion dates during different phases of our project. Most importantly, you were able to complete this project six weeks ahead of time, resulting in huge savings for us.

It has been a pleasure dealing with you over the last few months and we would gladly recommend Colli Constructions to anyone planning a construction project.

Ivan Saw, Managing Director

Scottech  |  Forrestdale


I would like to confirm our gratitude for the professional work completed during the construction of our new facility. Brendon Barbour (VB Commercial Realty) and yourself ensured a smooth process from the land purchase through to final construction and handover.

Your personal approach, updating drawings at our request, various trades attended as planned, and that way you kept the project moving, ensured we finished with a facility that met our requirements.

The fact that we completed the project four weeks ahead of schedule is testament to your personal oversight of the work.

Whilst we had a few ups and downs — as you would expect with any large-scale project — it was, and still is, a pleasure dealing with you. I would confirm our confidence to anyone considering a factory-type construction project.

Brian Maitland, Managing Director

Starkeys Products  |  Wangara


I would like to take this opportunity for the very professional job you have done, to date, with the construction of my new factory-warehouse. You were recommended by Brendan Barbour from VB Commercial Realty as one of the best builders in the Wangara area.

Since signing the building contract, it has been smooth sailing. You have been onsite every work day to check that trades are doing everything according to plan, and without fuss, have sorted to perfection any odd changes I have requested.

Most importantly, my project is nearing completion some four to six weeks ahead of the scheduled timeframe. This is a significant saving for me, as I’m paying a hefty rent at the current premises.

It has been a pleasure dealing with you over the past months and I would not hesitate to recommend Colli Construction to anyone contemplating a factory construction project.

Wayne Carew-Reid, Managing Director

Cat Haven  |  Shenton Park


Cat Haven was in need of some urgent building work and approached 3 builders to provide quotes.

Peter and his team were the first to deliver a quote, which was by far the most competitive.

I would highly recommend Peter and his team at Colli Constructions to anyone in need of a quality builder.

I would also like to thank Peter for the exceptional service, workmanship, patience and attention to our requirements.

Colli Construction was the perfect choice to complete our commercial extension at Cat Haven. We were kept in constant communication throughout the process which made handover and our expected time frames seamless.

We have since used Peter and his team for another (smaller) job at Cat Haven as we were so happy with their work.

It was an absolute pleasure dealing with Colli Constructions and we wouldn’t hesitate to recommend them to anyone who is planning a construction project.

Roz Robinson, CEO

Golden Choice  |  Perth


I would like to take this opportunity to thank Peter and his team at Colli Constructions for the work completed at our new retail fresh market in Perth.

Your quality of work, familiarity with building requirements, attention to detail, ensured a smooth construction process with a very professional outcome.

We found that your communication and informed updates kept our minds at ease and were much appreciated.

Your company worked well within our time frames and teamed well with our other suppliers to achieve our desired outcome.

It was a pleasure dealing with Colli Constructions and we would be more than happy to recommend your company to anyone who is planning a construction project.

High Flyers  |  Wangara


Thank you for building our Trampoline and Gymnastics Academy from designing of building right through to hand over of the completed building. In the time this was being completed we had nothing but professional, caring and organised discussions to help us along the way.

This is the first time we have built from design through to completion, we were made to feel part of the whole process from beginning to end. The building was finished early and to a top professional quality. Due to the nature of our business we required a unique build and we got exactly what we required. We were also allowed to move in early. Any issues afterwards, there are always going to be teething problems, are dealt with quickly and amicably.

We would recommend Peter and Colli Constructions to any of our associates in the industry. We look forward to having Peter as a landlord

Suzette VanderLaan  |  Kelmscott


I am very pleased to have my first house built by Colli Constructions. They made the building process stress free. I was updated on the progress through text and email. The communication from Peter was good throughout the entire construction phase. Peter was always willing and happy to answer any questions and did so in a timely manner. Throughout the whole process, from the beginning to handover of my home, the team at Colli Construction have been nothing short of professional.

I was very impressed with the quality of work and the attention to detail spent on the house. The timeframe which it was built in was quick and efficient and I am very pleased with the final product. I greatly appreciate their efforts in building me a house, I now have a beautiful home to live in.

It was an absolute pleasure building with Peter and the team at Colli Constructions. I would recommend to anyone to build with them.

Our Lady Of The Rosary Church  |  Doubleview Parish


Over the latter quarter of this year our Church building has undergone a considerable amount of renovation. This has included a new roof, installation of air conditioning, replacement of internal and external lighting, a substantial upgrade of electrical and audio wiring and quite a lot more. This work has been professionally undertaken by Colli Constructions.

Colli Constructions was one of five (5) companies whose details were communicated to us by theArchdiocese lastJuly. All of these companies were asked to submit a quotation to complete the work and after receiving these a thorough selection process resulted in Colli Constructions being selected.The only slight reservation was that this company, being one of the smallest of the group, might lack something in comparison with the bigger ones.

Now that the project has been fully and satisfactorily completed it is clear that our concerns were completely unfounded. Colli Constructions, led by their DirectorMr.Peter Colli, has completed everything that was agreed upon in the contract in an exemplary manner, satisfying everything that we required. Mr.Colli is very experienced and knowledgeable and was able to plan our work with great foresight, advising us fully of the necessary project steps and the actual and potential roadblocks with a can-do approach, giving us great confidence that we were in good hands.If there was anything that he did not immediately have an answer to he quickly resolved it via a member of his excellent team or network of experts that he could call upon.

We were extremely happy and satisfied with what Colli Constructions achieved for us and would certainly recommend them for similar work elsewhere and we would be prepared to confer with any other organization considering engaging them.
