"[7] His work reflects a commitment to the essentials of architecture, and to every project he brings "a profound interest in light, form, site, material, and craft.
[14] In 2016, Hariri presented a TED Talk about the Bahá'í Temple of South America that has since garnered over 1.4 million views.
[16] One of Hariri's earliest commissions, the Canadian headquarters of McKinsey & Company, received a City of Toronto heritage designation[17] just five years after completion.
The design reimagines the conventional office structure by implementing a new planning model called "The Hive," a dynamic, three-storey gathering space that blends light, form, and material.
[18] The Governor General's Medal-winning Schulich School of Business for York University was completed in 2003 in joint venture with Robbie/Young + Wright Architects.
The 340,000 square foot building, which spans a full city block, integrates an educational facility with luxury residential dwellings in a corporate learning complex.
[19] An early example of Hariri's high attention to detail and craftsmanship, the project was the first time the firm used a custom curtain wall system designed in collaboration with the manufacturer.
[22] Hariri was the Partner-in-Charge and lead designer of the acclaimed Bahá'í Temple of South America in Santiago, Chile.
[24] In 2019, the Temple was the first project by a Canadian firm to win the RAIC International Prize—a biennial award that recognizes a single work of architecture that creates lasting transformation within its societal context.
The jury report noted, "The architects resolve a challenging and prescriptive program for a new Bahá'í Temple near Santiago with a powerful form that creates a new landmark - a jewel - in a dramatic natural setting.
One juror compared the sight of the temple in the distance to a visitor's first glimpse of Ronchamp, creating a sense of procession and heightened anticipation in the experience of approach and arrival.
"[25] Hariri has mentioned that the Temple was "the project of a lifetime," noting his personal connection as a member of the Bahá'í community.
[27] In 2016, Hariri was invited to participate in a design competition to reimagine the Stratford Festival's Tom Patterson Theatre from a pool of over 50 international architects.
