In collaboration with landscape architects Land Morphology (the prime consultant), Olson Kundig worked to developed a master plan for the Upper Gardens at the Leach Botanical Gardens in eastern Portland for the City of Portland Parks and Recreation. The 80-acre project builds upon prior master planning efforts to propose site, building and garden improvements, as well as offering business plan recommendations. The Upper Garden plan is organized using ecological and cultural transects as conceptual and spatial framework. Olson Kundig focused on the design of a complex of four buildings and terraces including welcome center, offices and gift shop, event center and partner offices, while Land Morphology led schematic plans for a series of new gardens, including an Alpine, Physic and Water Gardens with fen, bog and giant plants, Secret Garden, Children’s Garden, and a Chroma Garden. An elevated tree canopy walk, pollinator gardens and event lawn, fireplace, terrace and arbor, are included as near term projects.
