As one of the host cities of the 2026 FIFA World Cup, Toronto is preparing to welcome fans from across the globe. The Canadian city, the fourth largest in North America, has become a cosmopolitan center with its renowned business district and cultural venues that come alive during the summer and early fall nights. Toronto offers a beautifully diverse urban setting, with shimmering high-rises and smaller brick houses, intertwining residential and vibrant commercial areas, public parks, and even beaches. All become part of the city's striking skyline, crowned by the iconic CN Tower.

Toronto's ongoing sprawl and constant urban development are evident as new projects spread through the city, weaving themselves into existing buildings, from 19th-century landmarks such as the Gooderham Building to major contemporary works like the Aga Khan Museum. These new constructions include increasing adaptive reuse and retrofitted projects throughout the city as more efforts and incentives are provided to reduce carbon emissions.

Material Minds, presented by ArchDaily Materials, is our new series of short interviews with architects, designers, scientists, and others who use architectural materials in innovative ways. Enjoy!

Green, or living, walls have begun popping up and growing across commercial interiors everywhere over the last decade. To understand how a living wall functions, and how to design one, we went straight to a pioneer in the profession: Ms. Birgit Siber of Diamond Schmitt Architects in Toronto. The synthesis of natural systems and building systems had been in her mind since her days as a student, but the major break came in 2000, when her team constructed a massive living wall for The University of Guelph-Humbar. To understand how architects are closing the gap between interior and exterior via the living wall, read the full interview after the break.

Architecture begins with ideas—and, for Will Alsop, sometimes with a painting. This interview is the first in a series of conversations with internationally prominent architects conducted by Sanam Samanian and Alex Bozikovic. The British iconoclast gives an overview of his creative process: why he's bored by the details of building; why we shouldn't think of architecture as a “profession"; and why we should think of architecture as a way to make life more joyous.
