About Us

Polyline Designs Inc. was formally established in 2021 as an evolution of the former Polyline Drafting and Designs (since 1994). Both partners have experience in Part 9 building design as well as site/landscape design. All of our projects effectively use the site’s natural landscape features to capitalize on natural sunlight and to integrate the building into the natural contours thereby reducing unnecessary and costly earthworks and disturbance. This design approach is applied to all our projects, both residential and commercial.
