James Lomax Simpson

James Lomax Simpson was the most prolific Port Sunlight architect. He was the son of William Lever’s childhood friend Jonathan Simpson (1850-1937) and also Lever’s godson. In 1905 he set up a private architectural practice, but by 1910 he became head architect for Lever Brothers. By 1917 he was a director of the company, leading Lever Brothers’ and later Unilever’s Architecture Departments.

Lomax Simpson was responsible for the existing design of The Diamond. He designed all the housing in this area, the sunken rose garden, boating pond, war memorial, Leverhulme memorial and Jubilee Garden. He and his team also designed:

  • Jubilee Crescent at the southwest end of The Diamond
  • The Ginnel
  • Duke of York Cottages
  • 1920s housing on Greendale Road and Windy Bank.

After the Second World War, Lomax Simpson oversaw the rebuilding work and contributed to the earliest phase of work to refurbish the houses for modern living.
