The History of Portland Works

History of Portland Works

Portland Works is located on Randall Street within a heritage conservation area otherwise known as the 'John Turner Triangle'. Portland works is the last remaining example of a purpose built conservation area metal trade works, other similar building were demolished in the 50's and 60's as part of the 'slum clearance program'.

The building was commissioned by Robert F Mosley and designed by architect J.H. Jenkinson. Planning permission was approved on the 15th September 1876 and the build work began soon after. Immediately after the completion of the building workshops were sublet to craftsmen such as William H Green, a spring knife maker and George Gill who was a cutlery manufacturer.

After changing location from West Street to Portland Works R.F. Mosley & Co Ltd was the first company to ever produce stainless steel at the works and operated at the site until the 1950's.  

Today, the successful metal trade businesses that operate within the works use the original machinery and tools that have been there since the beginning. Wigfull Tools, Stuart Mitchell Knives, Shaw Engravings, PML Plating and PH Engineering continue to use and preserve these elements of the works so that they will be available for years to come.
