Assiniboine Park Conservatory nearing end of its life, slated to close permanently April 2

Winnipeggersand tourists will have one less hot spot to visit in the city and warm up in after this spring.

TheAssiniboine ParkConservatory will closepermanently in April.

The lush, humid and importantly for many Winnipeg residents and winter visitors,warm indoor horticultural attraction, which is more than a century old, has exceeded its lifespan and must be demolished to make way for the final phase of the park's $200-million redevelopment, the Assiniboine Park Conservancy says.

That redevelopment includes the new Canada's Diversity Gardens.

The conservatory building was constructed in 1914 and remodeled in 1968. Its last day open to the public will be Easter Monday, April 2.

Starting March 27, the conservatory will hold an open house-style celebration for its last week of operations. Visitors are invited to submit written, photographic and video memories by March 2 to be included in a slideshow presentation.

The open house will run from 10 a.m. to 2 p.m. daily during the conservatory's final week.

Demolition will commence in the spring, followed by construction of supporting greenhouses for the Diversity Gardens. Eventually, the site will be redeveloped into green space for public use.

"We understand that the conservatory has been a favourite gathering place for Winnipeggers and Manitobans alike for over a century, and we recognize the significance of the loss for members of our community," said Bruce Keats, chief operations officer for the conservancy.

"The closure of this building is the next step in bringing Canada's Diversity Gardens to life."

Plans for the eventual closure of the conservatory were made as far back as 2009. In recent years, problems with the building have grown, and conservancy officials say it is only a matter of time before a major failure forces the immediate closure of the facility.

Problems with the exterior of the building, as well as heating and ventilation systems, have been mounting due to the high humidity and the need to maintain a warm internal temperature, coupled with extreme temperatures outside.

"Even this past six weeks, we've experienced a boiler failure and some other failures that really confirm that decision that makes spring the right time to do this," said Archie Pronger, head of facilities and capital projects for the conservancy.

It has committed to recycling at least 80 per cent of the building materials, including concrete, metals and wood. However, most of the plants inside cannot be transplanted.

"The larger material, like the trees, they're too big to move. Their roots are all growing into each other and they're of a size that they're not transplantable," said GeraldDieleman, project director for Canada's Diversity Gardens.

Instead, the conservancy is working to partner with woodworkers to turn some of the trees and plants into mementoes of the conservatory. Some of the smaller plants might be moved to the Toucan Ridge indoor exhibit in the AssiniboinePark Zoo, Dielemansaid.

"It's a good thing. We're sad to see this go, but we're building a bigger future and we're really excited about that."

Canada's Diversity Gardens is estimated to cost $75 million and is expected to open in 2019.
