What Roche + Roche Landscape Architecture does
Roche + Roche Landscape Architecture is a private, founder-led landscape architecture firm established in 2005 and headquartered in Sonoma, California. The firm provides end-to-end landscape design services — master planning, schematic design, design development, construction documentation, and construction administration — for two primary client segments: high-net-worth residential estate owners and hospitality operators (wineries, resorts, boutique hotels) across Northern California wine country, including Napa and Sonoma counties and select expansions into Marin, Carmel Valley, and Silicon Valley.
The firm's core technical differentiator is deep specialization in California Mediterranean-climate landscape design, with particular emphasis on sustainable, drought-adapted, and fire-safe planting design. Founding partner Nancy Roche's agronomy and soils-science background anchors a horticultural capability spanning plant selection, sourcing, procurement, and post-installation support that extends for years beyond project completion. The practice collaborates with a network of more than 60 architects, interior designers, builders, and landscape constructors, and has earned sustained ASLA recognition from 2015 through 2026, including a 2015 National Honor Award for the Sweetwater Spectrum community.
Revenue is generated through project-based professional services fees, with pricing quote-specific and not publicly disclosed. Client acquisition is relationship-driven, primarily through referrals from the architectural and builder community and direct studio engagement. The firm operated under the Roche+Roche name from 2005 until May 2026, when it rebranded to Cultivar Landscape Architecture alongside the promotion of Salvador Davila to partner and the addition of Danielle Davila as partner. No external institutional investment, M&A activity, or geographic expansion beyond Northern California has been disclosed.
