Site constraints 9

New River conservation area
Demolition needs planning permission and permitted development is restricted.
The council must give weight to preserving or enhancing the area's character and appearance. Not every council has published its boundaries as open data.
Council document ↗
Protected view corridor: 1A.2 Alexandra Palace viewing terrace to St Paul's Cathedral
Inside the landmark viewing corridor of a protected vista. A building that rises above the corridor's threshold height should be refused. How high that is depends on where along the view the site is.
The London Plan (policy HC4) designates strategic views, and the Mayor's London View Management Framework (March 2012) gives 13 of them a protected vista toward St Paul's Cathedral, the Palace of Westminster or the Tower of London. A vista has a threshold height that rises or falls with the line of sight. In the landmark viewing corridor, a building above it would harm the view and should be refused. In the wider setting consultation area around the corridor, a building above it is referred for consultation and its effect on the view is judged. The threshold changes along each view and is set out in the framework. A revised framework is out for consultation until 4 December 2026 and is not yet in force.
