English Heritage has welcomed plans to redevelop the 1930s Lots Road power station in west London into a mixed use residential and office building and build two tall buildings on the site, provided the original control room can be retained. It said that the development would enhance river views and the skyline without damaging the historic environment. It rejected plans for a 306m tower at London Bridge saying that it would be 'inappropriate and unsympathetic to the character of Southwark and two protected strategic views of St Paul's cathedral'. The proposals were assessed using Guidance on Tall Buildings launched jointly with the Commission for Architecture and the Built Environment last month.
