The '2nd Home Counties Field Co. Royal Engineers, Tower road west' also provided premises for Hastings & St. Leonard's Cadet Corps for Working Lads at the drill hall. (Kelly, 1911)

In St Leonard's-on-Sea, the one time home of the head quarters and the right section of the 5th Sussex Battery, 2nd Home Counties Brigade Royal Field Artillery still stands in Hatherley Road. Now known as the Seaview project, it provides a drop-in centre for local people.

Plans exist in the East Sussex Record Office that date the building back to 1872, and the Hastings News, 31st January, 1873, reports:
'Volunteers Shed
A new shed was to be the HQ of the 7th Cinque Ports Artillery Volunteers, on the corner of Hatherley Road and Southwater Road. It was economy and utility. 90 ft x 60 ft, with inside drill hall 80 ft x 40 ft. Thomas Elworthy was the architect, David Parks the builder. £650 plus land. The roads in its neighbourhood were a mass of mud a foot deep.'

On 14th March, 1873, the News reported the CPAV dragged two 40 pounder Armstrong guns from Hastings Station to their new depot. They then started drill for breech-loading.
