Workshop Range N Of No. 244A

The building is a workshop range located north of No. 244A on Southtown Road, constructed between 1853 and 1855. Originally part of the Militia Barracks, it was converted to light engineering works in 1971. The structure is made of red brick and features Welsh slate roofs, with a U-shaped plan surrounding a courtyard. It is a single storey building with two remaining sash windows on the north side, while the rest of the windows are late 20th-century casements. The roof is gabled, with hipped ends, and the internal layout was opened up in the 20th century.

Historically, this site includes the Lodges, Barrack Block, Armoury, and Workshop, which date back to the original Board of Ordnance store built between 1806 and around 1815. This store was intended to support the fleet anchored in Yarmouth Roads during the Napoleonic Wars from 1793 to 1815. The design is likely attributed to James Wyatt, who was the Architect to the Board of Ordnance from 1782. The workshop range is one of two barrack blocks that remain from the site's conversion into Militia Barracks in the 1850s. Additional alterations occurred after the site was purchased by Coleman's, a food manufacturing company, in the 1890s. Some of the original Napoleonic buildings, including storehouses and a magazine, were destroyed during bombing in the Second World War.
