At the heart of Mount Vernon, 1118 and 1120 Saint Paul Street embody Baltimore's architectural legacy. Designed and once occupied by George A. Frederick - the young prodigy behind Baltimore City Hall and the city's park system - these brownstones reflect both history and craftsmanship. Now, for sale within them are three distinct condominium units: a dramatic parlor-level suite with soaring ceilings and ornate detail, alongside expansive lower-level spaces with flexible layouts and private entries. Together, they offer owner-users a rare mix of historic pedigree and practical adaptability in Baltimore's cultural core. The properties are part of an established condominium association, with each unit carrying its own deed and monthly fee. Nine deeded parking spaces are also available for purchase, providing a rare convenience in Mount Vernon. The largest of the offerings, Unit 3 encompasses 3,571 sq. ft. across 16 rooms with two half baths. Located on the lower level with a direct entrance from Biddle Street, this suite was most recently configured as a physical therapy office. Its layout features a series of smaller rooms and treatment areas, offering flexibility for professional or creative use. While not as architecturally ornate as the parlor-level suites, Unit 3 provides an expansive footprint that could support a variety of purposes - from office use to live/work adaptation with the addition of a kitchen. Its private street entry and scale make it a practical option for owner-users seeking functionality with room to customize. Unit 3 also connects internally to Unit 1, creating the option to combine the two for a total of 5,508 sq. ft. This assemblage blends multiple private entries with expansive floor area, adaptable for larger-scale office use.
