Join us for Doors Open 2026

We are looking forward to opening our studio to visitors for Doors Open on Saturday, May 23, from 10 a.m. to 5 p.m.! 

This is your chance to see our working environment as an integrated landscape architecture, architecture, and urban design studio. Drawings, renderings, and photographs of DTAH projects in various stages of development will be on display to showcase how we are continuing to shape Toronto. We will also feature a selection of Partner Emeritus Robert (Bob) Allsopp’s hand-drafted drawings, spanning from his student days in the 1950s through to his early work at DTAH. 

As part of the Toronto Society of Architects (TSA) Open Studio program, we are offering free presentations that respond to this year’s Doors Open theme, The World in a City. The schedule is as follows:

11:00 a.m. Park for All: The Community-Driven Design of St. James Town West Park by DTAH Senior Associate Elnaz Sanati

1:00 p.m. Letting Nature Soak In: Toronto’s First “Sponge” Park, presented by DTAH Senior Associate See-Yin Lim and DTAH Architect Felix Cheong 

3:00 p.m. A Street for Everyone: Inclusive Design on Queens Quay, presented by DTAH Associate Corin Latimer

We are located at 425 Adelaide St. West, across from our national award-winning project, St. Andrew’s Playground Park. Volunteers will be in the lobby to guide guests to our studio.
