The design concept for the Rennie Art Gallery Roof Garden seeks to provide a high quality open space integrating seamlessly with the Wing Sang building and its surrounding environment.The design evolved from initial ideas balancing the constraints and opportunities unique to this project. The Integration of these concepts within the buildings heritage results in a small palette of carefully chosen materials. The garden becomes a recessive backdrop contrasting the frenetic city and is employed as a foil to the permanently displayed art collection.The soft landscape reflects the desire for a quiet contemplative space whilst referencing the past and future narratives of the building. Birch Trees are planted along the West boundary of the roof garden and are selected to symbolize a new beginning. Poppies and chrysanthemums make reference to Chinese heritage and gardens, utilized in the South and East boundary planters they provide seasonal highlights flowering in late spring and early autumn.Cor-ten steel is employed to reflect the industrial heritage of the area. The material will weather and age emphazing a new phase of the buildings history. The steel is used to form the walls of planters and decking boards and creates an enclosure to the roof garden, framing the space.The central area is designed to allow unobstructed views of the sculptures and to the city beyond. The Dan Graham Pavilion and Thomas Houseago ‘Striding Man’ sculpture are placed within the central area on a fine ornamental lawn.
