John Nash (18 January 1752 – 13 May 1835) was a British architect responsible for much of the layout of
Regency London under the patronage of the Prince Regent, and during his reign as
George IV. Nash was also a pioneer in the use of the
Picturesque in architecture. His best-known buildings are the
Royal Pavilion, Brighton, and
Buckingham Palace (though the facade facing
The Mall is an early 20th-century remodelling by
Aston Webb of an 1850s wing by
Edward Blore, and thus is not Nash's work).
