  • “Not knowing how to start our renovation process, Bill has been wonderful and easy to work with, bringing all of our ideas and wishes into a concept and plan that we love. He is extremely knowledgeable of the building industry with many suggestions of design features that we would have never considered. Bill continues to manage our project, working closely with the builders and external contractors, ensuring that all the details are executed.”

  • “Lisa and myself for years fantasised about designing our own home and forever discussing the features and elements we would use, if we were able to. When the decision was made to fulfil our dream, with so many ideas and thoughts and conflicting ideals, we needed a chaperone to guide us through the journey that is building your dream home. Enter Bill Hinchcliff from Trennel Architecture, the missing ingredient, who through thoughtful discussions and tactful ideas turned a blank page into the cohesive collection of ideas and elements that has become our home. We are so very thankful for the detailed consideration and expertise Bill has provided us in making our dream a reality, while maintaining our excitement in realising our goal in a final product that we are so proud of.”
