Barton Street and Cowley Street are two short streets in Westminster, London. They were developed in the 18th century by the actor Barton Booth, the former taking his first name, and the latter the name of an estate he owned at Cowley, then in Middlesex to the west of London. The streets' proximity to the Palace of Westminster has made them a popular choice for politicians looking for homes within Parliament's Division bell area; the Liberal politician Walter Runciman lived at No.8, Barton Street in the 20th century, and Jacob Rees-Mogg lives at No.7, Cowley Street in the 21st. They have also attracted other notables including; T. E. Lawrence, who wrote much of his Seven Pillars of Wisdom at No. 14, Barton Street; the actor, John Gielgud, who lived at No. 16, Cowley Street and the composer Ralph Vaughan Williams, who had a six-year tenure at No.10, Barton Street. Many of the buildings are listed, most at the second highest grade, II*. Simon Bradley and Nikolaus Pevsner, in the sixth London volume in the Buildings of England series, describe Barton Street and Cowley Street as, "among the most perfect Early Georgian streets in Westminster".
Barton Street and Cowley Street run in a dog-leg from Great Peter Street in the south to Great College Street in the north, lying to the south of the grounds of Westminster School.
Barton Booth (1682 â 1733) was among the most successful actors of the 18th century. He invested some of the profits of his success in property development, laying out Barton Street, named after himself, and Cowley Street, named after his country estate in Middlesex, from 1722. Booth was familiar with the area having been educated at Westminster School, just to the north.
Simon Bradley and Nikolaus Pevsner, in the 2003 revised London 6: Westminster in the Buildings of England series, consider the streets, "among the most perfect Early Georgian streets in Westminster". Westminster City Council noted the unusual residential nature of the streets, together with Lord North Street and Gayfere Street, describing them as "remarkable surviving residential terraces". The houses are mainly of London stock brick, of three storeys with basements and attics and with decorated doorcases. Their layout follows what John Summerson called "the insistent verticality of the London house" [see box]. There are some later insertions, mainly of the later 19th and 20th centuries, including: Corner House, which incorporates No.11, Cowley Street, and No.8, Little College Street, and dates from 1911 and is by Edwin Lutyens; No.4, Cowley Street, of 1904 by Horace Field and described by Historic England as "rather out of scale with its neighbours"; and No.8 Barton Street, of 1909 and also by Field.
