Ansonia Clockworks is an 8-story, early 20th-century factory-to-condo conversion in Park Slope, Brooklyn. Constructed in 1920 and sensitively reconfigured into condominium lofts, the building preserves industrial character through oversized, multi-foot-tall factory windows, lofty ceiling heights and exposed structural elements while offering contemporary condo comforts. Residences are primarily two- and three-bedroom loft layouts with open-plan living/dining spaces, large kitchens with islands or full cook setups, plentiful customized built-ins, abundant closet storage, and in-unit laundry in many homes. Shared building features include an elevator, full-time doorman (evening hours), live-in superintendent, gated entry and a meticulously landscaped internal courtyard and gardens that create a sheltered outdoor extension for residents. The property is pet-friendly and provides access to private outdoor spaces on some units such as balconies or terraces; deeded indoor parking has appeared for sale or lease separately. Located one block from Prospect Park and steps from 7th Avenue’s shops, restaurants and markets, the building offers immediate neighborhood access plus nearby F/G subway service. Overall, the Ansonia balances historic loft proportions and light-filled interiors with communal green space, concierge-style staffing and the everyday conveniences of a Park Slope residential address.
