Developing Long Island:
Harmony Healthcare Long Island
Garden City, NY Following the acquisition of 400 Oak St., Harmony Healthcare Long Island (HHLI) relocated its administrative headquarters to a 20,000 s/f space within the building designed by TPG Architecture. The move presented a unique opportunity to create a modern, flexible environment that empowers its people to carry out the organization’s important mission.
A preference for private offices defined HHLI’s previous space, but through interactive programming exercises, visits to vendor showrooms, and workshopping layouts in a temporary space, TPG identified how best to support HHLI’s workflow. A fresh, white palette with colorful, HHLI logo-inspired accents is complemented by warm, light wood tones. Glass partitions offer privacy while maintaining openness across individual workstations, private offices and phone booths, huddle rooms, and collaborative areas, fostering both teamwork and individual focus. The layout also includes a café and a boardroom.
Sustainability and individual wellness were key to the design and pursuit of Fitwel certification. Modernized HVAC and smart lighting systems enabled the integration of occupancy, daylight, and indoor air quality sensors to optimize energy use, airflow, and temperature control throughout the day.
The courtyard at the center of the building is being activated with seating areas, gardening and zen spaces, and a water feature to create both visual and physical connections to nature in potentially high-stress or cognitively demanding moments.
By redefining how its team works for the future, HHLI’s new administrative headquarters enables the non-profit to continue advancing its mission to provide accessible and compassionate healthcare to Nassau County.
