Whether Weston Grove House was also used for this purpose is not yet confirmed. The Royal Navy also had a large site between Archery Road and the waterfront, on land that was originally part of the Weston Grove estate. Built in 1917, this building was half a mile long and was originally used as a rolling mill, to produce brass strip that was used to make small calibre shell cases. The depot was subsequently used as Royal Navy stores, finally closing in 1987. Weston did not become part of Southampton until 1920, when it started to become more urbanised. A consequence was that Weston Lane was widened to cater for the motor car, demolishing two impressive stone arches built by William Chamberlayne (MP) that allowed him to cross between different parts of his "Weston Grove" estate unhindered by the Weston Lane. The arch at the upper end of Weston Lane was demolished in 1931 and the arch at the lower end was demolished in 1948. In 1909, an act of Parliament required that of land be sold to London and South Western Railway, by Tankerville Chamberlayne, for the purpose of building an enormous dry dock some . Although the land was acquired, the project didn't proceed. The site was subsequently sold to the Ministry of Munitions and the Rolling Mills were built instead. Situated directly below Weston Grove House, the Rolling Mills building obstructed the view of Southampton Water from Weston Grove House. The house was demolished in 1940. The site was subsequently used to build the Telephone Engineering Centre, in Archery Road. Although there is some pre-war housing in Weston Lane, near Holy Trinity Church, the bulk of Weston was built to meet the post-war demand for new housing in Southampton. Many of the first new homes in this area were prefabs. Some of those supposedly temporary buildings still exist, suitably modernised. Modern Weston mainly consists of housing estates and Tower blocks. It suffers some of the problems that are associated with this type of housing, but "Hampton Towers", "Havre Towers", "Oslo Towers", "Copenhagen Towers", "Rotterdam Towers" and "Canberra Towers" are a very distinctive landmark when approaching the port of Southampton by sea. Weston borders Southampton Water at a shingle beach where some 1930s beach shelters can still be seen. These have been repainted white. This is Southampton's only remaining shoreline and is a good place to observe Southampton's double high-tide. Weston Shore draws large crowds for every cruise liner that makes its first or final trip along Southampton Water to the port of Southampton.
