Promethean Structures was started by Emile Hanna in Toronto, Canada in 2018. In 2023 we moved our business to Barrie, Ontario. He wanted to put his passion for design and function to use as he fell in love with the European aesthetic and materials. With over 12 years of experience with plasters and concrete, we know that you cannot offer an aesthetically superior product without the same level of quality installation, we strongly believe this. Our philosophy is that we offer artistic, European finishes to your space while using products that will stand the test of time and are installed by a professional and trained team. We serve Barrie, Thornbury, Blue Mountains, Collingwood, Creemore, Muskoka, Newmarket, Bradford, Innisfil, Midland, Orillia, York Region, Meaford.

Our custom furniture, customizable in shape and finish, adds a personal touch to your space. Our concrete installation service is meticulous and thorough, making sure every detail meets your expectations. We are passionate about creating organic spaces and we take our installations very seriously. From consultation to installation, you can expect nothing short of exceptional service.

Our work lives at the intersection of artistry and architecture, turning everyday spaces into textured statements through microcement, limewash, Venetian plaster, and custom concrete furniture.

Whether you’re building from scratch or reimagining an existing space, our materials invite creativity without compromise. We specialize in low-thickness, seamless applications that bring a natural, tactile quality to modern interiors.
