Architects Rasch Eckler Associates led the restoration of a beautiful glass conservatory in Toronto. The Allan Gardens Palm House revitalization has been recognized with the Ontario Heritage Trust's Lieutenant Governor's Award for outstanding contribution to heritage conservation.
The 11-million-dollar revitalization of the 1910 Edwardian-era glass conservatory, which was originally designed by City Architect Robert McCallum, reinstated the building's defining architectural elements while upgrading its performance, accessibility, and long-term durability. The project replaced overhead glazing across the 16-sided dome and cupolas with laminated glass panels featuring ceramic fritting to reduce solar gain while preserving the luminous character.
Throughout the construction period, the glass conservatory remained open to the public. The building's renewed role as a venue for horticultural exhibitions, concerts, and community programming offers residents a year-round destination for education, cultural events, and social gatherings.
