Treehouse Silicon Valley - opening Spring 2025
Design & Technical Lead, Planting Design
Embracing an origin story of the Edible Eclectic, Treehouse Sunnyvale is filled with botanical riches that honor the site's agricultural past, from fruit orchards and backyard gardens to historical oak woodlands and foraging grounds. On this adaptive reuse site over 120 mature trees have been protected and over 300 new trees planted, including native Oaks, Redbud, Toyon, Redwoods, and an abundance of fruiting trees. Under the layered tree canopy, guests can wander and forage on huckleberries and kumquats as they travel to the farm-to-table restaurant, where garden beds overflow with ripening vegetables and herbs.
Every moment at the Treehouse is narrated through a botanical story.

Plan
As guests enter the resort, a massive Coast Live Oak is the centerpiece of the arrival court, ringed by pollinator-loving flowers. In autumn, acorns from the oak can be harvested and milled for baked goods.
At the restaurant event lawn, native grasses and wildflowers are grown as a meadow that can be selectively mowed for events, creating a sense of immersion in nature. We ask that you ‘Please pick the flowers!’ The wildflower seed is sourced from Larner Seeds, whose mission is to “give back territory to the native plants that evolved to support the insects, the soil, the birds, the watersheds, and the unique and varied natural beauty of California.”
Just beyond the meadow, a 100-year-old Sevillano olive anchors a collection of willow-woven outdoor vegetable beds. Willow Farm, a local willow grower and weaver, makes these elements. Willow Farm’s craft extends to the woven arbor, flanked by Kwanzan cherry trees and delightful woven and vine-covered trellises. Stepping outside of the suites, layers of lush planting provide private oases for guests where they will discover huckleberry and currant bushes, strawberries, and dappled sunlight.
The Woodland Swim hole, surrounded by mature Elms, is screened by ferns, jasmine vines, and strawberry tree shrubs. A wood board, sustainably sourced, winds down to this magical sunken retreat, where the water reflects a break in the canopy and pulls in light from the sky above.
Over half of the site is irrigated using reclaimed, recycled water, which reduces demands on the potable water system. All irrigation includes weather sensors, moisture meters, and high-efficiency irrigation for the climate-adapted plant palette. Runoff water is directed to biofiltration swales planted where riparian native plants biofilter impurities from the water before being captured into the reuse system, further reducing demand on infrastructural systems.
