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.
