The Lost in New Haven Museum has filed a plan to expand into a neighboring lot on Hamilton Street, including construction of a two-story building with a roof deck.
Lost in New Haven, currently at 80 Hamilton St., curates a collection of about 20,000 objects, along with photos and film, documenting 400 years of the city’s history.
The museum plans to acquire a vacant industrial building at 60 Hamilton St., in the city’s Mill River District.
The first floor of the planned building would be 4,600 square feet and include additional exhibit spaces and offices, according to documents submitted to the City Plan Commission.
The second floor would include a space for rotating exhibits, a conference room, a catering space, a meeting space and offices.
A roof deck is planned to provide space to display large artifacts, such as portions of buildings in New Haven that have been demolished, and a green roof that will be planted with sedum and low-growing grass.
The museum is open to the public and says it will expand its hours and tours during 2026.
The property is currently zoned for light industrial use, and the museum has also applied to the Zoning Commission for a variance.
