LM-ESP, in collaboration with Design Associate JLG Architects, joined forces as a multi-national team to lead the design of the International Peace Garden Conservatory Expansion, situated on the Canada-U.S. border between Manitoba and North Dakota. The design of the new facility was recently recognized with a distinguished Prairie Design Award of Merit in the small projects category.

Project Role

The International Peace Garden Conservatory Expansion unlocks the ability for one of the world’s most diverse indoor collections of cacti and succulents to continue to grow and be properly cared for, while raising awareness of the importance of preservation. A high-volume sanctuary for plant growth and public engagement is brought to life. New support and workspaces allow horticulturists to efficiently maintain and nurture the collection. Holistic upgrades to the greater building (the Interpretive Centre), including a redeveloped café and expanded programming opportunities to host diverse events, workshops and interactive exhibits, help to foster an intersection of connectivity, conservation, and education.

Design

The minimalist greenhouse remains in constant conversation with the site’s context. Through transparent poly-carbonate paneling, users can enjoy direct forest and nature views, while passersby can glimpse plant life silhouettes and activity at a distance. The expansion’s orientation, lighting and materiality illuminates an all-season interior landscape. The focus is drawn to the biological oasis of desert flora and fauna, including rare and endangered species from across the globe. Within, curving pathways embrace slight elevation changes, planning for exciting exploration, accessibility and clear sightlines. Seating areas paired with meandering pathways around planting beds provide an immersive experience of play and education with invited moments of rest and reflection.

Sustainability

A key focus was to create a sustainable microclimate. Operable awning windows open to reduce heat buildup, motorized curtains provide shade protection overhead, and direct sunlight floods the space. Sustainable energy sources, thermal massing, energy modelling and daylighting informed the design. A high volume of material content was also procured locally, notably the Douglas Fir beams framing the facility, which were supplied just down the Canadian road.

Special to this endeavour, the project prioritizes equal country representation across design and construction teams, resources and building materials. The Conservatory expansion opened in 2024 as a primary campus attraction for international visitors.

Congratulations to the Client, International Peace Garden, the full project team involved and all Prairie Design Award recipients this year.
