Gilbert Murray Simpson friba (1869–1954) was a British architect from Brighton who did most of his work in the seaside resort.
He took over the firm of Thomas Simpson & Son when his father died in 1908, and went on to design several other institutional buildings in Brighton.
After his education at Bishop's Stortford College, he started his career in architecture in 1886 as an articled clerk to his father at his office at 16 Ship Street, Brighton.
[5] Simpson qualified as an Associate of the Royal Institute of British Architects (ariba) in 1893; his proposers were Thomas Lainson, Lacy Ridge and A.
Simpson designed the brown-brick building in the Neo-Georgian style and gave it an "attractive" main hall with balustraded galleries.
