  • Cometbay design is a boutique business providing a very high quality service that tick all the boxes when it comes to design and drafting. Without any doubt, Peter Jenner has clearly a very good understanding of his customer's needs and for us we can confirm that he has delivered on our project at both design and drafting stage. From day one, Peter has taken the time to listen to our needs. During the various design and drafting stages, he was always available to give us ideas and he has recommended key changes to our design that has made this project viable, achievable and within budget. As we are writing this recommendation for Peter, we have now gone past council approval stage and are about to build this nice home and we could not thank Peter enough for his imagination and technical skills.  Thank you Peter for everything and all the best.

  • Thank you very much for taking care of the whole Development Approval process for our Townhouse and Unit Development. Your reliable services and care shown towards our projects have saved us time and stress. Definitely looking forward to working with you again if another projects comes up.

  • We approached Peter to assist in the design and drafting of our new beach house build in the southwest and after our initial consultation we felt very comfortable working with him as he listened to what we had to input and developed our idea’s into a draft design within a week. Correspondence with Peter via email to make alterations and give feedback was effective and made the entire process very easy and allowed us to progress rapidly to working drawings and a 3D design without having to make multiple trips to Mandurah. Comet Bay Design comes highly recommended and the entire process working with Peter from initial concept to working drawings was a pleasure. Thanks again,

  • We first utilised the services of Comet Bay Design for our project at the 19th Tee Estate in Meadow Springs. We are a Building Company and it has been refreshing to work with the likes of its Principal, Peter Jenner, who has been able to produce very good design concepts and in turn document them clearly in a practical sense so as to ensure things run smoothly during construction. We have found Peter to be responsive and easy to work with and we would not hesitate to recommend him to any potential clients.

  • Our experience designing our dream home with Peter, from Comet Bay Homes was first class from the very first phone call, all the way through the design process, and well into the building process, when we still received phone calls from Peter to check on how our house was coming along. The service he offers is a step above the rest. He has a professional, friendly and calm manner, achieving an amazing result. He always listened carefully to our ideas and turned them into a beautiful home, on a block that was certainly not a standard shape and size. We loved the 3D walkthrough tour of our house during the design process. He was always quick to get back to us with changes and adjustments during the design process, and proactive with his communications. We highly recommend Peter from Comet Bay Homes.

  • We have been using Comet Bay Designs to detail our framing system for the residential building industry for the past two years. Without any doubt, Peter Jenner has been very precise with the detailing of our system. Previously we were using other companies which involved a lot of modifications on site.

    Peter has gone out of his way and worked closely with us to overcome a lot of the problems we were experiencing.  The service and turnaround time along with the fees are outstanding. Therefore I can without any hesitation recommend Comet Bay Design. Should anyone have any questions please do not hesitate to contact me.

  • We have found Peter Jenner to be very professional in his approach, to transforming our ideas, into a design that is exactly as I pictured. Peter was able to give professional advice and the 3D model Peter provided for us, was extremely helpful in visualising our ideas. Peter was always readily available to hear and make any changes for us. I highly recommend Peter's design services to anyone looking to build.

  • Peter Jenner provided us with invaluable technical expertise in assisting to prepare a range of exclusive home designs for Central Park Mandurah.

  • Peter was a past work colleague of mine and when he started Comet Bay design I knew how good he was at drafting and design. On the first occasion, I utilized him to draft up a fit out for a commercial business we established which included all plans, layouts, electrical, cabinets and a 3 d Model so we could apply and get our council approvals through which we did.

    On a recent occasion I have engaged Peter to draft 2 double storey units including a 3D walkthrough for the rear of our development property. Peter has worked with the R codes and the design to a point where we have council planning approval to build these and the documentation and proposed strata plans drawn for our submission into the Planning commission for our subdivision application.

    Peter is very knowledgeable, professional and I highly recommend him for any drafting requirement.

  • Peter Jenner from Comet Bay Design provided us with a fast/efficient professional service, provided quality consultation and customer service, listened to our requirements and transformed our thoughts into final working drawings of a quality second to none. Even more impressive was the stress free process and Peter's ability to interpret our requirements correctly the first time. We have no hesitation in recommending Peter to anyone in need of quality service and construction plans. 

          Reg & Ana Hughes  -  South Yunderup  - February 2014

  • As an owner builder, we found our dealings with Peter were extremely pleasant .  Not only is he highly efficient , but also offered us broad range of design ideas, that personalised our home. As we are new to the Mandurah area Peter assisted us with organising quotes and dealings with local expertise. We are really pleased with the service that Peter has offered and would not hesitate to recommend his services to other owner builders.

  • As we needed to find a home designer for our canal lot that could capture our ideas due to the fact we don’t currently reside in Mandurah, engaging Peter Jenner worked very well for us. We provided Peter with our ideas and he turned them into a very pleasing design. One of the features of Peter’s work was the 3D model that was provided at each step of the process. This really helped to visualise our ideas and Peter was very cooperative with the many changes we made.

  • It was a pleasure working with Peter Jenner to design our family residence.  To gather information for the design, he listened carefully to our description of what we were trying to achieve, and he brought a depth of professional experience in making suggestions when we asked for them. He personally showed us through the finished design with ease and expertise. We are very pleased with the result, and freely recommend his design services.

  • This is our third design with Comet Bay. We have got the home we want and are looking forward to building it. Being able to walk through it using the Virtual Building Explorer has been invaluable. Our new design has incorporated the old with the new and maintained a great continuity between the two.

  • I have used Comet Bay design for work on a commercial project and found them to be quick, efficient and accurate. They have very sophisticated software and are able to produce 3D plans that they can email to you for approval so you can look at your plans from all angles and know exactly what you are getting. I would not hesitate to recommend Comet Bay design.
