Established in 2005, MOSS SUND Architects is a boutique architecture firm located in the bustling Leslieville neighbourhood of Toronto, that specializes in modern, environmentally conscious design. Led by principals Carolyn Moss and Simona Sund, the firm’s work and reputation now spans the country.
The creative team brings a synergy of experience, ingenuity and collaboration to your project. Whether designing a wellness center, a medical facility, a commercial building or a custom home, the underlying goal remains the same: to leverage our creative skills and network of consultants and contractors to create the best possible solution for our clients.
For each project we take a wide range of input, from client vision and budget, to building codes, materials, energy efficiency, zoning by-laws, building science and constructability and bring them together to create what seems like an effortless, elegant outcome – it’s architectural alchemy and it’s what we love to do.
Grounded in expertise and driven by passion, the MOSS SUND team are engaged in every aspect of the project, from pre-design to permit and contract applications through to construction and hand-over. Friendly and easy to work with, meticulous and focused, we are committed to the success of your project.
MOSS SUND is proud of the work we have done for our clients over the years and look forward to working with you on your project!
MOSS SUND takes great pride in the long-standing partnerships they have established with many of their clients.

THE HOUSE IS FANTASTIC!!! You have created something extraordinary. There are days when I am close to tears at how lovely it is -sounds so sappy I know, but true nonetheless.
