80 The Strand

Project Overview

Grade II* Shell Mex House, also known as 80 Strand, was constructed in 1931 and opened in 1932.  The building occupies a prominent location between The Adelphi building and The Savoy Hotel.  It was designed by architectural firm Messrs Joseph, with Frances Milton Cashmore himself responsible for most of the work.

The art deco architectural style is enhanced by the largest clock face in London positioned on the south side of the building, which was known as ‘Big Benzene’ for a time.  Standing 190ft tall and with 49,900m2 of floor space spanning 12 floors (plus basement and sub-basement) it offers some of the largest floor plates within the West End.
