About this home

Presenting Navy Yard 33 in Charlestown, Massachusetts. This 47-unit, loft-style apartment building is ideally located along Charlestown’s waterfront. Built at the turn of the 20th century, the building has since been masterfully renovated and modernized while still maintaining many of the building’s original features. The building is comprised of forty–seven (47) units, offering residents a variety of one- and two-bedroom floor plans from which to choose. The building was constructed in 1900 and renovated in 2008. The unit mix includes 18 (38%) junior one-bedroom apartments, 13 (28%) one-bedroom flats, 1 (2%) one-bedroom duplex apartment, 6 (13%) two-bedroom apartments and 9 (19%) two-bedroom duplex apartments. While the property has been exceptionally well maintained, there is significant potential for selective upgrades such as improved bathroom and kitchen lighting, smart thermostats, and modern fixtures.
