Built circa 1858 probably by Alexander Roos, architect to the Bute Estate. The original houses from Mount Stuart Square development were later adapted for business use. It is a three storey, one window building with a slate roof and brick chimneys. It has stucco finish and the second floor windows have broad tripartite openings articulated by Doric pilasters. The ground floor of No 8 has a square-headed doorway and to its right a large three-light shop window with modern round arched glazing.

It is listed as a significant survivor of the oldest domestic buildings in Mount Stuart Square, converted to commercial use.
