Set on iconic Ossington, just west of downtown, this address sits at the centre of the city’s creative pulse, surrounded by independent retailers, destination dining, and a vibrant street culture that defines the neighbourhood. Hullmark’s vision, realized in collaboration with world-renowned Hariri Pontarini Architects, celebrates the intimate scale and heritage character of historic Lower Ossington while pushing confidently toward a sustainable, design-forward future.

“There’s a kind of simplicity, a matter-of-factness. It feels approachable and honest — like a good work of art, quiet yet engaging in its context.”

This four-storey building presents a refined interplay of old and new materials, textured and transparent surfaces, and contemporary interpretations of the arches that define the street’s architectural heritage. Every detail has been carefully considered to create a building that both complements the vibrant streetscape and stands as a distinctive expression of Hullmark’s commitment to authentic, enduring design.
