Critical to the resiliency of Stephen Avenue Place was the need for greater integration with the public realm . We transformed the previously low-visible podium into a transparent and accessible mixed-use environment that will support the tower’s long-term success .
The ground, second and third floors are fully renovated with upgraded retail, dining hall and restaurant spaces .
Tenant amenities include an exclusive lounge and games room, as well as a conference centre and club-quality fitness facility on the fourth floor .
The rebranding attracts tenants, generates new spending through enhanced visitor experiences and improves the quality of urban life .
The revitalization of Bow Valley Square consists of a complete transformation of a four-tower city block complex . We reimagined the podium’s interior and exterior to modernize its urban presence and strengthen pedestrian access .
The design replaces the podium’s aging façade with large glass storefronts and refreshed concrete . The addition of entrance canopies, exterior lighting and upgraded signage increase the complex’s visibility and boost the vibrancy of the public realm .
A showcase for innovative urban renewal, the Campus reinvigorates a legacy building as a vibrant work environment . Located within the former Sears retail space at the CF Toronto Eaton Centre, the design transforms the previously opaquely clad façade with transparent glazing, raising the building’s prominence .
This progressive flagship supports the client’s business transformation . Focused on strategic partnerships, industry-leading customer service and investment in technology, the Campus reimagines the traditional workspace as a vibrant, collaborative environment .
A revitalized entranceway and forecourt plaza with lighting and planters activate the street and guide pedestrian traffic into the space .
This new luxury hotel development converts the former Four Seasons Hotel, currently integrated with the CF Pacific Centre . The proposal involves a complete renovation of the existing tower, with comprehensive seismic upgrades and an interior reconfiguration .
The design transforms the tower’s urban presence . We reversed the internal organization of the podium, placing all public functions along the exterior façade allowing occupants to experience meaningful moments of curiosity and discovery with street life .

We transformed an underused commercial building into rental residential with 65 units . The floor plate is subdivided while the existing core and structure is retained, and a new mechanical unit allows for the increase in load . We replaced the façade with a new wall assembly and relocated the entrance to provide a better sense of scale . The conversion adds urban homes, builds community and provides vibrancy to the neighbourhood
We are restoring this historic 1896 Philip Jamieson Building back to its original prominence after decades of alternations . The design includes a three-storey addition set back making it visually distinguishable from the heritage building . The design elevates the heritage attributes while providing a more accessible, flexible and connected space to the adjacent CF Toronto Eaton Centre shopping centre
Sherbourne Estates uses a high-performing overclad system to renew an existing tower-in-the-park development, while celebrating the original brutalist architectural character .
Designed as a “second skin,” the comprehensive retrofit improves thermal comfort, energy efficiency, air tightness and operational costs .

Continuous louvre
Sheet metal over frame
New window wall with insulated shadow box
Envelope improvements include insulated spandrel panels fixed on top of the existing brick façade and a new double pane window system . We introduced electrical appliances and PTAC upgrades to eliminate reliance on natural gas, a leading source of greenhouse gas emissions .
New window wall with vision glass
Insulation between frame
Existing brick and CMU knee wall
Existing kneewall with a new thermally broken window assembly and insulation. Thermal bridging of the continuous concrete slab extends beyond the envelope without insulation. The surface behind the existing insulation is at risk of condensation.
Overclad kneewall with an air and vapour barrier (AVB) on the outside face of the brick and mineral wool insulation exterior to the AVB. The solution prevents condensation and thermal bridging.
The revitalization modernizes this landmark glass enclosure to make
The profile of the roof will remain virtually untouched . The existing glass is replaced with larger panes, improving energy efficiency and maintenance through the reduction of unnecessary connections and seals .
Additional design drivers include drainage, glare control, integration of electrical systems, wind and snow studies, and the replacement strategy . Allowing the shopping centre to continue regular operations during construction is critical .
Our refurbishment of the Palm House restores the defining heritage elements of this 1910 Edwardian horticultural pavilion . The upgrade preserves the distinct architectural language of the site, while improving its operability and accessibility .
To improve the performance of the enclosure, the overhead glazing of all three domes is replaced with laminated glass panels . Coupled with improvements to mechanical and electrical systems, the retrofits result in better indoor air quality, energy efficient operations and more stable indoor temperatures .
