The Diwan is a year round pavilion and event space for the University of Alberta Botanic Gardens and the final piece to complete the 4.8 hectare Aga Khan Garden, Alberta. The site of the pavilion was designated in the original concept plan for the Garden, inaugurated in 2018. In addition to providing multi-use functionality, the pavilion was to resonate with its rich surroundings, and extend the themes of the Garden, a contemporary interpretation of Islamic landscape architecture in a northern climate and context. The pavilion was designed to complement the spirit of the Garden’s design, heritage and experience. (Figures 1,2). The term diwan has varied historical definitions, and here implies a space for meeting, cultural exchange, and celebration.
The design team’s research began with the underlying themes of the Chahar Bagh garden typology commonly used in Mughal gardens, a key source of inspiration for the Aga Khan Garden. The function, scale, and detailing of the historical garden, as well as the pavilions within them, were a source of inspiration, as were broader traditions of Islamic building arts. Geometric patterns, surfaces, and screens are embedded throughout the Diwan, and further enrich the visitor experience of building and garden. The design, massing, and material selection is that of a contemporary building that interprets traditional principles.
The Diwan is designated to be the University of Alberta Botanic Garden’s only year-round facility. It includes a large event space, servery, coat check, washrooms, and universal access to the rooftop terrace, providing panoramic views back to the garden. In creating a facility for performances, conferences, workshops, exhibitions, or weddings, the architectural design ‘offsets’ some of the symmetries of the Aga Khan Garden while adhering to others, to balance the formal garden context with the pavilion’s internal function and focus on a well-serviced ‘public room’.
The Diwan has a strong yet understated presence within the Garden. Its horizontal form hovers along the southern edges of the Garden. A sizeable overhang provides for shade and shelter marking its entry and offering an uninterrupted view into the main hall and through to the woodland forest beyond (Figures 3,6,7,11). It lies symmetrical to the Garden’s north-south axis, acting as its terminus and marking the garden’s edge with the forest. The architectural form was carefully considered to integrate with the scale of the surrounding garden elements in a seamless manner.
The Diwan will be a beacon of gathering and intellectual interaction. It will be a home of the arts and of celebration, as well as a symbol of rich heritage, tradition and cultural pluralism. It is imbued with cultural sensitivity and historic legacy, while remaining responsive to its garden settings, programmatic requirements, and the context of northern Alberta. In the evening, the Diwan will serve as a beacon, illuminated by a warm and welcoming lantern-like light
