Parnell House

Parnell House is a block of artisans' flats built in 1849 by Henry Roberts for The Society for Improving the Condition of the Labouring Classes. The building features yellow stock brick with rusticated stucco on the first and second floors, along with stucco dressings. It has fireproof construction with brick load-bearing walls and arched hollow-brick floors, and it has an L-shaped plan.

The exterior consists of five storeys and a basement, with a top storey added later. It has six bays and a twelve-window return to Dyott Street. The stucco doorway is surrounded by an architrave, with a cornice supported by console brackets and a pediment above. A plain stucco band at the second floor level is inscribed "MODEL HOUSES FOR FAMILIES." The square-headed recessed sash windows have stucco lintels shaped like gauged flat arches, and the ground and first floor windows are set within stucco recesses. There are stucco sill bands at the second and fourth floors, along with a stucco plinth and a bracketed brick cornice. Open galleries in the courtyard, supported by brick piers spanning two floors, provide access to the flats, which typically include a kitchen and scullery, a living room, and mostly two bedrooms.

Originally known as Streatham Street Buildings, Parnell House is the earliest surviving example of flats designed to accommodate the "deserving poor" in regular employment. The second earliest survivor is New Court on Flask Walk.
