Post First World War, tea blender and food manufacturer J. Lyons and Co. were looking for a secondary site on which to expand production beyond Cadby Hall, Hammersmith.

In 1921 they bought the first piece of an eventual 63 acres (25 ha) site, due to its location close to good transport links from both the Grand Union Canal and the Great Western Railway's Great Western Main Line, and the West Coast Main Line and onwards to the Midlands at Willesden Junction.

The factory officially opened in July 1921, with the first single-storey buildings known as "Zig-Zag" due to their northern light-aligned windows allowing maximum light into the production area.

The extensive onsite railway infrastructure allowed precise positioning of heavy raw goods into the factory, as well as the extraction of finished product.

Lyons bought their own steam shunters to move wagons between the GWR exchange sidings and the factory system.

A later pioneer in electronic machines and computing, Lyons deployed the latest factory automation technology, making Greenford a showplace that was regularly visited by the media, academics, competitors and royalty, with more than one visit by King George V and Queen Mary.
