Tower Hamlets Cemetery Conservation Area
Here are a couple of extracts from the Tower Hamlets Cemetery Conservation Area Character Appraisal and Management Guidelines document – (anyone needing full information should of course consult the full document and its guidance for further information):
The Tower Hamlets Cemetery Conservation Area was designated in November 1987 and is centred around the Victorian cemetery park in Bow. Bounded by Mile End Road to the north, the Conservation Area borders on the British Estate (built to replace the terraced row houses cleared in the 1970s) and includes the surviving residential townscapes of Brokesley Street and Mornington Grove, the St Clement’s Hospital site and Wellington Primary School…
…Before carrying out any work in this area, you will need to apply for consent even for minor work such as replacing railings. These consents include planning, listed building and Conservation Area consent, as well as others for work such as felling trees.
When planning applications in a Conservation Area are decided, the planning authority will pay special attention to whether the character of the area is preserved or enhanced. … In Tower Hamlets Cemetery, as in other Conservation Areas, planning controls are more extensive than normal. Consent is required to demolish any building, and a higher standard of detail and information is required for any application. When applying for listed building consent, please note that all parts of the building, including its interior walls, ceilings and all other internal features, are protected. Some buildings are nationally (statutorily) listed, and some are locally listed by the Borough to indicate buildings that the Borough wishes to protect…
…All trees in Conservation Areas are protected, and some trees are also covered by Tree Preservation Orders (TPO’s). Notice must be given to the authority before works are carried out to any tree in the Conservation Area, and some works require specific permission. More information can be found in the Council’s Guide to Trees, and on the Tower Hamlets website. Carrying out works to trees without the necessary approval
can be a criminal offence, and the Council welcomes early requests for advice.
