At Ernest Schieferstein Architecture, our team of architects and designers are dedicated to excellence. Our reputation is built upon strong and meaningful relationships with our clients. On projects large and small, and everywhere in between, we enjoy sharing ideas and collaborating for the desired outcome, seeing each project through to completion with a firm commitment to quality design and solid workmanship. We offer a full range of services from architectural designing to construction documents and project management.

Our firm has been steadily growing since its inception in 1982. From our roots as an architectural firm, we have expanded our base to include services in interior design as well as landscape design. A construction component was added to our firm in 1998, making our firm one of the few full service design firms in the east end.

Whether your project is modern, traditional, or includes special design elements, our team will take an individual approach. Our history of handling design challenges is visible in our portfolio, which is as diverse as our clients themselves. Also living in the community in which we work, we have a strong commitment to the environment and the use of sustainable materials.
