SYLA is an award-winning New York City based design studio creating innovative and ecologically productive landscapes that connect people to nature. Our work encompasses a diverse range of project types, including gardens, roof terraces, estates, courtyards, parks, plazas, and master plans. 

We don’t prescribe to a signature style, but instead let our clients’ desires and a site's physical, cultural, and historical context inform our design direction. Through an iterative process of research, analysis, and interdisciplinary collaboration, we respond to the challenges of each project with a highly creative and lasting vision for its future.

Both beauty and function matter to us.  We strive for each landscape we design to be visually stunning and experientially rich, but we're equally concerned with how a place will function and hold up over time. Will the space be comfortable and useable? Can the design adapt to changes in user needs, maintenance plans or environmental disturbances? Are the materials durable and details well-constructed?  Each design is put through a thorough process of evaluation and refinement at every phase to ensure the landscape will not only be beautiful, but also functional and resilient for years to come.

SYLA believes there is a fundamental human need to connect with nature and we see our work as a means to this end. Each new project is an opportunity to artfully fuse humans and nature in deeply meaningful and lasting ways.
