Founded in 2003 by principal architect Jason Grossi, studio g+G inc. is a Canadian architectural practice with an international portfolio spanning Canada/US and Europe. The studio is recognized for its distinctive expertise in integrating contemporary architecture with heritage structures, with a strong focus on heritage preservation and adaptive reuse.

The firm’s diverse body of work includes projects in the arts — such as museums, galleries, and exhibition spaces — as well as educational and campus facilities, residential developments, and more. Additional experience includes retail and office design, master planning, and industrial design.

As a design-focused studio, our process is deeply influenced by a collaborative and concept-driven methodology. We believe that architecture is inherently a dialogic process — every member of the project team has a voice, and meaningful design emerges from open dialogue and shared ideas.

Over the years, we have collaborated with a range of international design entities, acting as both design consultants and architects of record. Notable partnerships include work with Constantine George Pappas Architects and Planners and NBBJ in the United States, GBCA Architects in Canada and ABV in Moscow. These collaborations have been deeply rewarding, offering opportunities for architectural dialogue, knowledge exchange, and enriched collective experience.

From the beginning, studio g+G has sought to integrate sustainable principles at both site and building scales. Our commitment to environmental responsibility continues to guide each project through the use of sustainable strategies and conservation of our built heritage.

Each design challenge — whether architectural or not — presents an opportunity to explore the intersection of concept, function, and place. Programmatic needs, site conditions, and spatial potential form the foundation of our design thinking. We do not impose a predetermined style or form; rather, we allow the project’s context and intent to inform an architectural response that engages with time, space, light, and materials in a meaningful way.

At its core, our work aspires to leave a positive and lasting mark. We believe that thoughtful, enduring architecture can enrich lives and communities. Our goal is not merely to solve problems, but to transcend them — to create work that offers something valuable to the present and to the future.

Jason Grossi is the founding principal of studio g+G inc., architect, an award-winning architectural practice recognized for its design excellence and work in heritage preservation. His studio also serves as a platform for his ongoing research-creation and participatory research initiatives.

In parallel with practice, Jason is an Associate Professor of Architecture and Visual Arts at the University of Windsor’s School of Creative Arts (SoCA) and program coordinator for the Visual Arts and the Built Environment (VABE) program.

Originally trained in orchestral composition and performance, Jason brings a unique interdisciplinary perspective to his work, treating architecture and music as parallel creative processes. This dual background informs his approach to design, where spatial and structural ideas are developed with the same sensitivity and nuance as musical composition. He often references the relationship between old and new as a thematic variation — grafting contemporary interventions onto historical contexts with care and precision, much like completing or reinterpreting a classical work.

Jason’s architectural portfolio spans a wide range of typologies and scales — from large urban developments and multi-functional institutional projects to small-scale, critically sensitive adaptive reuse interventions. His work includes museums, university buildings, arts facilities, private residences, and even custom-designed furniture and hardware. Across all scales, his design philosophy aspires to the ideal of the Total Work of Art — where every element contributes to a unified and meaningful whole.
