HHT’s principal effort is the preservation and maintenance of the historic buildings under our care. From managing major restoration projects to coordinating daily maintenance needs, HHT and NYC Parks are crucial in ensuring that these important places are preserved into the future.
Capital Program
Thanks to more than a decade of advocacy by our partners, colleagues, and neighbors, over $140 million in capital funding—the largest investment in HHT’s history—is transforming our 23 partner sites. Our team of Architectural Conservators are leading 24 city-funded projects, combining technical expertise, community collaboration, and advocacy to not only preserve these treasured historic houses, but reimagine them as vibrant, accessible, and enduring spaces that inspire and enrich New York City communities for generations to come.
Morris-Jumel Mansion Restoration
Construction is officially underway on a major restoration of the Morris-Jumel Mansion, a treasured 1765 landmark and Manhattan’s oldest surviving residence.
Swedish Cottage Marionette Theatre Restoration
As the Cottage approaches its 150th anniversary, a major capital improvement effort to preserve and enhance the beloved Central Park landmark begins.
Research
As part of our capital projects and ongoing preservation work, HHT and our preservation partners conduct critical research to ensure the long-term care and resilience of our network of historic sites. This work includes climate resiliency studies, materials investigations, and technical assessments that guide restoration strategies and preservation decisions. By combining historical research with scientific analysis, HHT helps protect these cultural treasures and ensures each site can continue serving its community safely and sustainably for generations to come.

Maintenance

Working in close partnership with NYC Parks and a network of private contractors, our team addresses the diverse and evolving needs of each site with care and expertise.
