Dyad Studio is a Washington, D.C. based, full-service landscape architecture practice working at a national scale. Founded in 2024, the studio operates as a flexible network of designers, assembling project-specific teams that combine the depth and resources of a large firm with the agility, craft, and attentiveness of a boutique practice.

Our work is grounded in a systems-based approach to landscape architecture, treating each project as a living framework shaped by ecology, culture, and long-term change. We focus on creating resilient, high-performing landscapes that support human well-being and strengthen connection to place.

Dyad Studio’s portfolio includes parks and public spaces, streetscapes and transit corridors, therapeutic landscapes, residential environments, rooftop landscapes, and nature-based play spaces. We collaborate closely with clients and communities to define clear goals and deliver inclusive, durable landscapes built to evolve over time.

Dyad Studio is licensed in Washington D.C., Virginia, Maryland, and Oregon. We hold certifications in CBE/LBE/SBE/ROB.
