the people
Private Pension Partners, in collaboration with PCL Construction, required a comprehensive retrofit strategy to address critical building envelope failures in an occupied residential tower. f-BLOK worked closely with the client, consultants, and design-build team to understand the technical challenges and operational constraints of upgrading a 1960s building while residents remained in place. The process prioritized minimizing disruption, maintaining safety, and ensuring continuity of daily life for occupants throughout construction.
Led by f-BLOK as prime consultant, the team provided architectural services and coordinated structural, mechanical, and electrical disciplines from assessment through construction. A detailed building condition review informed the scope of work, identifying deficiencies and guiding targeted interventions. Through close collaboration and careful phasing, the project team managed complex upgrades within an active residential environment, balancing technical performance with the needs of the people who call the building home.

the result
The 8-storey, 135,000 sq. ft. residential building, along with its 37,000 sq. ft. parkade, underwent a major retrofit to resolve long-standing humidity and temperature control issues caused by a failing building envelope. The project delivers a high-performance upgrade that improves comfort, durability, and energy efficiency while extending the life of the building.
To achieve these outcomes, the design focused on envelope renewal, system modernization, and careful coordination within an occupied setting. The result is a cohesive and resilient building system that meets current performance standards without displacing residents.
Key features and program elements include:
Complete exterior recladding and envelope upgrades to improve thermal performance and airtightness
Structural remediation and replacement of key building components
Upgraded mechanical systems designed to meet current ASHRAE standards and address humidity control
Electrical system improvements integrated with broader building upgrades
Interior renovations coordinated with ongoing occupancy
Phased construction approach to minimize disruption to residents
Careful coordination of trades and systems to manage spatial and operational constraints
Full construction administration and warranty-phase oversight to ensure long-term performance
The result is a renewed residential building that addresses critical performance issues while maintaining continuous occupancy throughout construction. By upgrading core systems and the building envelope, the project enhances resident comfort, reduces operational challenges, and extends the building’s long-term viability.
