Firm Description

  • Steven Yavanian Landscape Architecture PLLC (SYLA) is an award-winning design studio based in New York City and Seattle, working on projects that range from intimate gardens and roof terraces to estates, public parks, courtyards, and plazas. We work with architects, developers, public and institutional clients, and private homeowners to create landscapes that are both visionary and enduring.

    We design landscapes that are immersive, ecologically productive, and deeply attuned to place. Our process combines research, analysis, and collaboration, drawing inspiration from the natural and cultural histories of each site. This approach allows us to uncover patterns and narratives that inform design decisions, ensuring every landscape is rooted in context rather than imposed upon it.

    Our work emphasizes clarity of concept, richness of planting, and material craft, producing environments that are as meaningful as they are beautiful. At SYLA, we see landscape architecture as more than shaping outdoor space. It is about creating places that support human well-being, restore ecological function, and reveal the unique character of each site.
