About the CompanyAt Harrison Green, we create landscapes that enrich daily life, foster connection, and bring enduring beauty to the places people call home. Our work spans city rooftops, townhouses, country estates, hospitality environments, and boutique commercial projects, each approached with the same commitment to thoughtful design, meticulous execution, and long-term stewardship. Operating out of our custom-retrofitted, light-filled commercial studio in Brooklyn, we have built a growing enterprise that has spent over a decade transforming the city's skyline.
