  • Recently spent some time with Jessie from Trinity Designs. He helped me get my thoughts and ideas for a few minor modifications into plans for Council. He was a good listener and very professional. I will use Jessie again and recommend him to others.

  • Trinity Design & planning has done a fantastic job for the design and drawing of my home extension. From very beginning to the end, they went out of their way to help us to get council approved for the project. They are very patient and keep communicating with us in terms of our and their professional ideas. I will not hesitate to recommend it to any of my friends should they plan to build their dream home. Well done! Trinity Design & Planning
