The Bloedel Floral Conservatory has been approved for a $1.3-million roof replacement.
The first phase of the project, which included the replacement of the centre dome panels and the section of roof over the entrance to the building, began in January.
Today, the council approved the plan for the entire roof to be replaced.
The park board says the triodetic domed roof was constructed in 1969 and is past its expected lifespan.
The roof is expected to be completed this fall. The Conservatory will remain open during construction.
Five years ago, the Conservatory was threatened with closure. But in September of 2010, the park board has approved a plan to partner the conservatory with the VanDusen Botanical Garden to avoid shutting it down due to budget concerns.
