Experiential elevated play sculpture inspired by natural elements, the Gumnut Grove is a sculptured play structure that overlooks the Golden Gate Bridge and is utilized by children agers 2-10 to discover and explore. The piece is located at the Bay Area Discovery Museum (BADM) which houses indoor and outdoor exhibits. The piece is made up of 3 bridges connected by copper cladded “Gumnuts” accessible by ropes, climbing structures, and a custom stainless steel slide, the design was inspired by the forms and a eucalyptus tree’s fruit which is found in the area. The Gizmo team used many different fabrication approaches to create the Gumnuts, bridges, climbers, and slide.


Repurposing an underutilized space on the Bay Area Discovery Museum campus in Sausalito CA, Gumnut Grove introduces a climbing activity area that allows children aged 5–10 to refine their gross motor skills, explore risk and develop confidence in a safe environment.


Award winning architecture firm Olson Kundig provided the site inspired concept that Gizmo and Surface Design Landscape Architects used to design and engineer the custom play structure. Gizmo utilized its digital fabrication and welding studios to create all the steel forms, structural bridge components, and custom copper gumnut housings, while adhering to rigid playground safety standards and the updated 2019 California Building Code to implement all the components.
