We used De Simone Designs for a rear addition project to our existing home. We were very happy with the great design, but even happier that they also kept us within our budget. Thomas worked out all the tricky construction details, which was a huge relief for first time renovators navigating the world of construction. His attention to detail and ability to balance aesthetics with practicality was truly impressive. What stood out the most to me was his willingness to guide us throughout the entire process. As someone who is not well-versed in architectural design or construction, I appreciated his expertise and his ability to explain things in a way that was easy to understand. He truly made the entire experience stress-free and enjoyable. I highly recommend this firm to anyone in need of an architectural designer.

It was a pleasure working with Thomas at De Simone Designs. We appreciated his fun approach to construction and design, as well as all the energy and work he put in to our detached garage project. The added space for my wife’s art studio on the second floor was amazing touch we hadn’t initially thought of. We were very pleased with this professionalism and the quality of his work. He presented different design options and took the time to review different colour options for the exterior. His professionalism, creativity, and commitment to his clients is truly unmatched.

I contacted Thomas for the plans for a renovation of my basement to add a new secondary apartment; I couldn’t have been happier with the results. His expertise in building and city codes was evident throughout the entire process, ensuring that all aspects of the design were up to standard. I was impressed by his office’s detailed drawings, which were not only aesthetically pleasing but also had a practical and functional layout. Thomas’ friendly and fun demeanor helped make this an enjoyable process. I will always recommend him.
