Environmental sustainability is the major value of Green Slate, and our mission is to find the right balance of people-centered and planet-centered design. We can help you create a space that has everything you need, but we'll do it in the greenest way possible. 


Our interior and exterior building concepts are as unique and full of personality as the people who they are designed for. With the help of Green Slate, you can have a home, commercial, or hospitality space that is one-of-a-kind and everything you imagined it could be and hoped it would be.


Owned and operated by Building Designer, Clarissa Froom in Guelph, ON, Green Slate is all about creating beautiful designs that are unique, functional, safe, sustainable, and doing it all at a reasonable price. It's our belief that everyone should be able to afford a great design, so we're doing our best to make function and style accessible for everyone. Call us today for an estimate!

Guelph - Toronto/Oakville/Mississauga - Brampton - Barrie - Burlington - Kitchener/Waterloo - Cambridge Hamilton - Niagara Falls - London - Stratford -  Listowel - Mildmay - Hanover - Mitchell - Kincardine - Goderich
