Posted on S HTrustindex verifies that the original source of the review is Google. As a local custom builder, we have engaged Trent & the TDM Design team to complete multiple projects. Trent's attention to detail in his design work and general care for his clients is exactly what we love about TDM. If you are a homeowner requiring Drafting services with an Architectural flair for renovation, extension or a new build then TDM is the one.Posted on Jane McDougallTrustindex verifies that the original source of the review is Google. We couldn't be happier with Trent from TDM Design. From our first meeting, he truly listened and understood not just what we wanted, but how we live and what matters to us. He took our ideas and added real value to them, helping us extend our heritage home in a way that honours its 100-year history while creating the space we need for modern life. The first set of plans he provided us were spot on!! What also impressed us was Trent's expertise in navigating the council approval process. We purchased the property at the end of September, and thanks to his skilful management of both council requirements and neighbour consultations, we had our green light by the end of December. That timeline seemed impossible at the start, but Trent made it happen. Trent project-managed all of the additional services needed to make the project happen. Surveyors, Engineers, and Energy Consultants, all of the same calibre and high standard. Beyond his technical skills, Trent is simply a wonderful person and a joy to work with. He partnered seamlessly with our builder (who recommended Trent), ensuring everyone's voice was heard and ensuring the smooth transition from design to construction. We feel incredibly fortunate to have found Trent and would recommend TDM Design without hesitation.Posted on Simon WardTrustindex verifies that the original source of the review is Google. Trent provided excellent service throughout the Town Planning and Working Drawings stages for our rennovation. He is highly knowledgeable, friendly, and detail-oriented in his approach, and guided us confidently through each step of the process. His communication was clear and consistent from start to finish, and I would highly recommend Trent.Posted on Grant RobertsonTrustindex verifies that the original source of the review is Google. Trent did an amazing design for our renovation. Excellent communication and went above and beyond to even assist with getting the building permit. 10/10!Posted on Shaun MarlowTrustindex verifies that the original source of the review is Google. We have had the pleasure to work with Trent and team at TDM design for the last 10 years on multiple difference projects. The team has an incredible eye for detail and provides a fantastic service from initial engagement, concepts, planning, dealing with consultants and councils to Final drawings and permits. The team provide outstanding communication and knowledge of the Building codes and council regulations and will always go above and beyond to make sure they can do everything possible to complete a project. We look forward to continuing to work with the team for all future projects.Posted on Jessica CraigTrustindex verifies that the original source of the review is Google. Getting Trent involved in our renovation was hands down the best decision we made. We were completely stuck on how to rework our layout, but Trent came in and quickly figured out the perfect design solution. He took all our ideas on board and transformed them into a plan that not only made sense but maximised the space in ways we hadn’t even considered. His expertise, creativity, and eye for detail made the whole process smooth and exciting. We couldn’t be happier with the outcome, highly recommend Trent to anyone planning a renovation!Posted on Nicole O'HanlonTrustindex verifies that the original source of the review is Google. We had a really great experience working with Trent, from TDM Design. From the initial consultation to the final drawings, he was professional, detail-oriented, patient and easy to communicate with. He took the time to understand exactly what we wanted, offered helpful suggestions, and delivered quality plans that exceeded our expectations. Trent’s knowledge of local building codes and council regulations was a huge asset, and it really helped streamline the process. We appreciated how responsive and timely Trent was throughout the entire project. We would certainly recommend Trent from TDM Design to anyone looking for a reliable and skilled draftsman. We’ll definitely be using them again!Posted on Tristan CincottaTrustindex verifies that the original source of the review is Google. Trent is a pleasure to work with and the only one I’ll work with.

What Are Concept Design Plans?
Concept design plans are the first step in the design process. Think of them as the “blueprint before the blueprint”—a big-picture view of your project that outlines how spaces will work, flow, and connect.
Unlike working drawings, which provide the fine technical detail needed for construction, concept design plans focus on layout, functionality, and feasibility. They allow you to explore ideas, visualise the possibilities, and make informed decisions before moving into detailed documentation.
Our Concept Design Process
01
Initial Consultation
We meet with you to understand your needs, vision, budget, and lifestyle goals.
02
Site Analysis
Every block is unique, so we assess site conditions, orientation, size, and any planning overlays.
03
Concept Sketches & Layout
We prepare preliminary plans that show how your spaces will connect and flow.
04
Feedback & Refinement
You’ll have the opportunity to review and refine your concept design until it feels right.
Benefits of Concept Design Plans

Visualise your project clearly before committing to construction.
Cost Savings
Identify potential design issues early, avoiding costly changes during the build.
Confidence with Council & Builders
Present professional, considered designs that make approvals and quotes easier.
Flexibility
Make adjustments at the planning stage rather than mid-construction.
Foundation for Success
