Boulton House occupies a site on Chorlton Street between Bloom Street and Major Street.  It was built in 1973 to a design by E. Kirby & Son.  John  J. Parkinson-Bailey describes it as "A modern interpretation of a Victorian warehouse",  which is appropriate because Boulton House was built to replace just such a building.  Ironically, the buildings along that side of Chorlton Street survived the WWII Blitz.  I have shaded the site in red on the aerial photograph below, dated 1953.

St Martins Property Investments have recently undertaken a major refurbishment of several floors of Boulton House to provide what they describe as, "high quality office space."
