Marlingford watermill machinery and possibly the mill building was refurbished in the 1850s when it was geared to run 5 sets of stones. It was built of rendered brick and weatherboard under a Norfolk pantiled roof. Although it finished grinding corn in 1912, the mill has been well kept. After milling ceased, it ran a turbine and pumped water to the hall via filter beds until the 1920s.

In the 1920s, a turbine and switchgear were installed to provide electricity for the hall and power a pump to push water to storage tanks at the hall via filter beds. The turbine was taken out of service in the 1950s.

In the 1780s Parson James Woodforde of Weston Longville often sold grain from his glebeland to local millers Ben Leggett, 'my farming man' would be despatched to take the grain by horse and cart, which would often be a full day's work as can be seen from the following excerpts from Parson Woodforde's famous diary:
