Construction is an industry that’s made relatively little progress in how it organizes its business, still using century-old technologies and processes. We believe digital capabilities present opportunities to make qualitative leaps for the industry. There have been piecemeal efforts made, but no significant revolution in overall project scale practice.

Horizon has built the first and largest 3D printed neighbourhood in Canada, pioneering the use of on site robotics and automation in construction.

Horizon is also creating a new Construction Automation Lab in Mississauga, Canada. The lab will serve as a hub for cutting-edge research and development in the field of construction automation, revolutionizing the industry and solving the problem of labour shortages currently experienced in Canada and globally.

Overview: Horizon Legacy is pioneering the use of robots in construction and solving the problem of labour shortage and affordable housing. Horizon is creating the first construction automation lab in Canada, located in Mississauga, Ontario
