About Aspect 120 Landscape Architecture P.C.

Aspect 120 Landscape Architecture P.C. is a principal-driven practice committed to creating landscapes that are purposeful, resilient, and deeply rooted in place. Our work is guided by nature, informed by context, and enriched by the cultural narratives that shape each site. We offer clients the highest level of professional involvement at every stage—from visioning and concept development to construction and long-term stewardship. Each project benefits from the direct leadership, experience, and design insight of the firm’s founding principal.

Our approach integrates ecological understanding, creative design thinking, and clear visual communication to deliver landscapes that are as functional as they are inspiring. Whether designing public parks, reimagining historic sites, or implementing green infrastructure, our work reflects a thoughtful balance of performance, beauty, and meaning. We believe that strong landscapes emerge through collaboration. By engaging with clients, communities, and interdisciplinary partners, we ensure each design is tailored, inclusive, and built to endure.

At Aspect 120, we craft landscapes with lasting impact—responsive to the land, reflective of their context, and connected to the people they serve.

Guided by Nature – Informed by Context – Enriched by Culture

 

Founding Principal

Susan Y Jainchill RLA, AICP

With over 30 years of experience, Susan Y. Jainchill has been a key figure in landscape architecture and urban planning projects throughout the New York metropolitan area. She has expertly led teams of engineers, architects, and natural resource professionals through design, documentation, and construction phases, often on complex and challenging sites. Her dedication is unwavering: to craft environments that enhance the quality of life, foster productivity, and promote well-being for individuals and communities.

As both a licensed landscape architect (RLA) and certified planner (AICP), Susan brings a cross-disciplinary approach to every project, skillfully navigating regulatory frameworks and municipal approval processes. Her experience spans large-scale efforts such as corporate campus master plans, public recreation facilities, and ecological mitigation for infrastructure projects, as well as smaller, site-specific initiatives including residential properties, playgrounds, and urban plazas. In every case, she combines analytical rigor, creative design, and practical solutions to deliver outcomes that are visually compelling, functionally effective, and cost-efficient.

Susan splits her time between her home in Athens, NY, and New York City. Her design practice is based in the Irvington, NY, office, from which she works on projects throughout the Hudson Valley and beyond. With a strong sense of civic responsibility, Susan is actively involved in her community. She is a former member of the Ardsley Planning Board and a past President of the Westchester County Historical Society.

Susan holds a Bachelor of Science in Landscape Architecture from Cornell University and a Master of Urban Planning from Columbia University’s Graduate School of Architecture, Planning and Preservation. She was a Lady Davis Fellow and is currently an adjunct professor at Fordham University.
