Contractor Collaboration
We regularly partner with builders who need a designer who speaks design, along with having fluency in the languages of construction, building code and building department. With 20+ years previously working in the trades from basic roles to lead carpenter and project manager as the foundation our company has been built on, and 12+ years serving Ontario with a specialization as a Toronto BCIN designer, we produce designs with drawings that your crew can build from while handling all permitting processing with target timelines that keep your schedules on track.
