Description

These are a pair of early 19th-century terraced houses on the north side of Flask Walk, Camden. The houses are constructed of stucco and rise to three storeys, each with a single window. A central, architraved doorway with panelled doors and patterned overlights is shared by the two properties, and is sheltered by bracketed hoods. Full-height, segmental-arched shallow recesses flank each house, containing recessed sash windows. A parapet tops the facade. The interiors have not been inspected.
