If someone has already created the definitive study of the LCC Weights and Measures, we have not found it. But we have found photos of 4 buildings built for this function, three still standing.
Responsibility for the testing of weights and measures was transferred from the police to the LCC in 1889. The LCC Public Control Department was established in 1891 with powers to exercise control over weights and measures in London.
Initially a house at 25 Mount Pleasant was used but the heavy work damaged the building such that it had to be demolished. New premises, the North Central Weights and Measures Office, were built at 5 Rosebery Avenue (1892–3 and still extent) on the corner with Warner Street. 1898–9 this got a large five-storey extension along Warner Street, on the sites of Nos 40 and 41 Mount Pleasant. In 1928 the whole site was sold.
has a photo of an LCC Weights and Measures Office on Calvert Avenue, Shoreditch, 1900. This also functioned as a Coroners Court. Built at the junction with Boundary Road in 1898 and converted to flats in 1998-9. Still standing, part of it seems to have been rebuilt in a less ornate style.
There was also an office at 169 Euston Road built in 1929. have a photo, shown here, and it was a nice restrained building, demolished c.2003.
The name of the Mount Pleasant office, 'North Central', suggests that there were, at any one time, multiple offices servicing different segments of London.
