The Teton River Basin is a private land conservation priority area in the 26 million-acre Greater Yellowstone Ecosystem. Among its most important ecological features is Woods Creek Fen – a 4,000-acre peat-forming complex fed by groundwater from the distant Teton Range.
The 1.2-acre project site rests at the edge of both the Fen and the community of Driggs. Analysis of the Basin’s wide hydrologic networks, rare flora and rich diversity of migratory bird species informed the site’s design and development.
In the early 2000s, a large-lot subdivision was approved on the edge of the Fen, its trajectory halted in 2008 due to the economy. Under new ownership, the half-finished development was resurrected in 2017. Our clients purchased a 1.2-acre lot.
Envisioned as a home in nature, Tributary House is inspired by adjacent rolling grasslands, ecologically diverse wetlands, and distant vistas. The planting palette mimics the indigenous landscape, blurring boundaries between gardenesque and natural landscape.
A collective vision reimagines a disturbed, 1.2-acre suburban site, transforming it into a restorative setting that responds to adjacent ecologies. In response to dated design guidelines, the garden represents a holistic approach to sustainable design and land stewardship.
Pre-graded, the site sat vacant, with minimal vegetative cover, for a decade. Today, contiguous landform and drainageways reconnect to adjacent lands. The design restores 90% of the landscape with a drought-tolerant meadow and exceeds tree planting requirements by 200%.
Initial conversations with the family revealed widely differing perceptions of landscape design. The team – inspired by author Wallace Stegner’s “Beyond the Hundredth Meridian” – promoted awareness and education of relevant Western sustainability topics.
Interior and exterior spaces coexist in a symbiotic relationship that communicates a deep appreciation for the landscape.
Set beneath an aspen canopy, the dining terrace extends the interior spaces into the landscape. Ornamental plantings attract pollinators.
The plant palette supports the ecological function and visual character of the fen wetlands, providing forage, nesting areas, and winter cover.
Guided by a vision of stewardship, the design team focused its efforts on designing an environment whose imprint would be light on the land.
Embracing the character of the setting, the design erases the line between residential and conserved lands, dissolving the home into the landscape.
Wrapped by native meadow and hidden from the public right-of-way, a modest mown green sits squarely between the house and natural landscape.
To reduce groundwater dependency, the team restored over 22,000 square feet of disturbed lands using drought tolerant, semi-arid native grasses.
Human-scaled gathering spaces are designed to immerse and engage users with the surrounding landscape.
The design prioritizes and guides visual character, nurtures biodiversity and enhances community benefits.
