[1][2][3] Purchasing a plot of land on part of the old Essex County Cricket Club ground on New Street,[2][3] Marconi commissioned architects W. Dunn and R. Watson to design a new purpose-built factory.

The Works were opened and ready for inspection on 22 June 1912 by the delegates of the International Radiotelegraphic Conference,[2] each of whom was issued with a commemorative booklet.

[1] In 1920, a number of licences were issued by the General Post Office in accordance with the Wireless Telegraphy Act 1904, for the purpose of conducting experimental transmissions.

The first occurred from New Street Works on 15 June 1920, featuring Dame Nellie Melba singing two arias and her famous trill,[2] with the signal received throughout Europe and as far away as Newfoundland, Canada.

Only the Grade II listed water tower, The 1912 front building façade, the New Street cottages and the power house will remain.
