New York Landmarks Conservancy

Technical Services Center

India House has restored its exterior with assistance from TSC.

The Blackwell House on Roosevelt Island in 1960 ...

... and in 2002, after repairs and stabilitization.

In 2002, Technical Services Center published The Brownstone Guide: Maintenance & Repair Facts for Historic Property Owners and made it available free as a service to the community.

Providing Architectural Expertise

New Yorkers are fortunate to be surrounded by diverse examples of architecture dating from the 18th to the 20th century. Owners of these historic buildings need access to objective, technical expertise to be able to care for them. Nationally recognized for its expertise, the Conservancy's Technical Services Center provides exactly that to owners of residential, religious, public, and commercial buildings.

Through the Preservation Hotline, the Conservancy fields questions about building repair, project management, and contractor referrals. For issues that cannot be resolved over the phone, the staff makes site visits and meet with owners, architects, and contractors. In some cases, we provide conditions reports, historical research, maintenance plans, or feasibility studies.

You can contact the Preservation Hotline with your questions at 212.995.5260 or by email.

Conservancy staff also serve as project advisors, offering assistance with requests for proposals, budgets, grant applications, nominations for listing in the National Register of Historic Places, certification of rehabilitations for federal investment tax credits, and local and state design review approvals. Historic property easements can be donated to the Conservancy, with assistance from Technical Services staff.

Through publications and workshops, Technical Services works to promote understanding of preservation issues.

Online resources offer detailed, practical guidance on specific building types, materials, and features.
