Policy HC4 London View Management Framework

HC4

  1. Development proposals should not harm, and should seek to make a positive contribution to, the characteristics and composition of Strategic Views and their landmark elements. They should also preserve or enhance viewers’ ability to recognise and to appreciate Strategically-Important Landmarks in these views and, where appropriate, protect the silhouette of landmark elements of World Heritage Sites as seen from designated viewing places.
  2. Development in the foreground and middle ground of a designated view should not be overly intrusive, unsightly or prominent to the detriment of the view.
  3. Development proposals and external illumination of structures in the background of a view should give context to landmarks and not harm the composition of the view as a whole. Where a silhouette of a World Heritage Site is identified by the Mayor as prominent in a designated view, and well-preserved within its setting with clear sky behind, it should not be altered by new development appearing in its background. Assessment of the impact of development in the foreground, middle ground or background of the view or the setting of a Strategically-Important Landmark should take into account the effects of distance and atmospheric or seasonal changes.
  4. Development proposals in designated views should comply with the following:
    1. London Panoramas should be managed so that development fits within the prevailing pattern of buildings and spaces, and should not detract from the panorama as a whole. The management of views containing Strategically-Important Landmarks should afford them an appropriate setting and prevent a canyon effect from new buildings crowding in too close to the Strategically-Important Landmark in the foreground, middle ground or background where appropriate
    2. River Prospects views should be managed to ensure that the juxtaposition between elements, including the river frontages and key landmarks, can be appreciated within their wider London context
    3. Townscape and Linear Views should be managed so that the ability to see specific buildings, or groups of buildings, in conjunction with the surrounding environment, including distant buildings within views, is preserved. 
  5. Viewing places should be accessible and managed so that they enhance people’s experience of the view.
  6. Where there is a Protected Vista:
    1. development that exceeds the threshold height of a Landmark Viewing Corridor should be refused
    2. development in the Wider Setting Consultation Area should form an attractive element in its own right and preserve or enhance the viewer’s ability to recognise and to appreciate the Strategically-Important Landmark. It should not cause a canyon effect around the Landmark Viewing Corridor
    3. development in the background should not harm the composition of the Protected Vistas, nor the viewer’s ability to recognise and appreciate the Strategically-Important Landmark, whether the development proposal falls inside the Wider Setting Consultation area or not
    4. development in the foreground of the wider setting consultation area should not detract from the prominence of the Strategically-Important Landmark in this part of the view.

Protected Vistas are designed to preserve the viewer’s ability to recognise and appreciate a Strategically-Important Landmark from a designated viewing place. Development that exceeds the threshold plane of the Landmark Viewing Corridor will have a negative impact on the viewer’s ability to see the Strategically-Important Landmark and is therefore contrary to the London Plan. Development in the foreground, middle ground or background of a view can exceed the threshold plane of a Wider Setting Consultation Area if it does not damage the viewer’s ability to recognise and to appreciate the Strategically-Important Landmark and if it does not dominate the Strategically-Important Landmark in the foreground or middle ground of the view. Development in the background of a Protected Vista that is inside or outside of the Wider Setting Consultation area should not harm the composition of the Protected Vistas.
