"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."

She told me building a house might lead to building more and I can see why. It's immensely satisfying to design something and then see it come to life! We were told the drafting would be 3-5 weeks and we took every bit of 5 weeks because we really wanted to take our time in between each revision. I'm glad they didn't hurry us because as a family we did not agree on certain details quickly. Love our forever home and so glad we chose the right place for the design and drafting."
