Opened to the public since 1860, the Allan Gardens Conservatory is one of the oldest botanical gardens of its kind. It is located at 19 Horticultural Avenue, at the intersection of Jarvis Street and Gerrard Street East. The conservatory is a tourist attraction featuring a variety of plants and flowers, where they are well appreciated as is the structure that contains them. The Allan Gardens Conservatory consists of multiple greenhouses: the Palm House, the Arid House, the Tropical Landscape House, the Cool Temperature House, and the Tropical Houses. These all branch off from the main entrance, which is the Palm House, as each greenhouse contains its own theme-based collection of plants. Former City Architect Robert McCallum is the key architect here though he mainly only created the Palm House, as it is seen as the main focus of the site. Structurally, the Allan Gardens Conservatory is primarily made up of steel, glazing and brick, where the steel and glazing are used for the upper portion as they are in all greenhouses, and the lower portions often are brick cladding if not stone panel cladding. Trusses are the main structural support in holding up the dome of the Palm House, as it also spreads throughout the other greenhouses in supporting their varying shaped roofs as well. The material used is rather consistent throughout each greenhouse, making them appear to be a ‘whole’ or in unison despite being individual buildings placed together.
