"We hired Sylvain and Marquis Assoc. To build a separate and detached Granny Flat on our property. He and his team built a 1200 sq. ft fully functioning 3 bedroom 2 full baths HOME. From start to finish Sylvain was personally involved and extremely professional. He and his team were on the job site on time everyday early to dusk. They worked hard and fast. Every night the job site was left clean. As soon as the city approved the plans, we were building the next day. It was incredible how efficient the guys were in building, total build time was less than 3 months. Craftsmanship was top-notch, and we feel we truly built a great house. He was focused on making sure we chose all of our counters/ cabinets/ doors/ windows/ molding/ everything that we wanted and stayed on budget. All done, Sylvain did not go over budget. His estimates were right on to what final costs came out to be. He kept us updated constantly regarding budget and where we stood in the process. We had changes along the way, and he treated all problems with calmness and found solutions to all issues. He is well seasoned and we trusted him completely. Our house is incredible, we are so happy. I also feel I need to mention how much our neighbors love the new house. They walked by during their daily walks every day during construction. Now they are stopping us outside and ringing our door for Sylvain s contact info now that he is finished with the project. We even have cars slowing down in front of the house to take a good look. We are extremely happy and highly recommend Marquis Associates."

With a career beginning in 2001, I bring the expertise of an Industrial Designer who has collaborated with civil and mechanical engineers and contributed to the film industry through sets, props, and stage builds. My work spans luxury homes, offices, restaurants, and bespoke commercial spaces. Every project is fully customized—your vision becomes a refined design, a detailed mock‑up, and a flawlessly executed final result. I begin with an accessible design concept so you can preview the outcome before fabrication. I specialize in modern, artistic, and precision‑crafted work using premium materials. I travel for select projects and adapt to any scale with discretion and professionalism. Client privacy is paramount; no past work is ever shared without permission. My commitment is simple: exceptional design, clear communication, and craftsmanship that elevates every space.
