In collaboration with Land Morphology, Olson Kundig is developing a master plan for the Upper Garden at Leach Botanical Garden in eastern Portland for the City of Portland Parks and Recreation. The 16-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 transepts as a conceptual and spatial framework. Olson Kundig is designing a complex of four buildings and terraces including a welcome center, offices and gift shop, event center and partner offices. Land Morphology is leading 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. The project also includes plans for an elevated tree canopy walk, pollinator gardens, an event lawn, fireplace, terrace and arbor.
