Great George Street is a street in Westminster, London, leading from Parliament Square to Birdcage Walk. The area of the current street was occupied by a number of small roads and yards housing inns and tenements. In the 1750s these were demolished and Great George Street laid out with "houses only as are fit for the habitation of persons of fortune and distinction". Part of the street was demolished in 1806 and is now part of Parliament Square. Between 1898 and 1915 the entire north side of the street was demolished for the construction of the Government Offices Great George Street. The street houses the headquarters of the Royal Institution of Chartered Surveyors, whose building includes the only surviving 1750s façade, and the Institution of Civil Engineers. The street formerly housed the National Portrait Gallery.
