The city is multi-dimensional. One of the main dimensions is time. Built up of layers of schedules — business operating hours, transit, garbage pick-up, deliveries, traffic lights, etc. — this continuous flow orchestrates the city’s metabolism.

This diagram depicts the operating hours of every business within a 200m radius from Canada Line’s Broadway-City Hall station at Broadway and Cambie. They are categorized by type and overlaid on the rapid transit line’s operating hours. The businesses are organized radially by duration of operating hours, from longest in the centre to shortest on the outside.

The graphic illuminates the utilization of commercial space over a day, and compares these factors in terms of duration.

As a recent Master of Architecture graduate from UBC SALA he’s excited to make the shift from student to practitioner. Check out to see more of his work.
