Policy 7.12 Implementing the London view management framework
A New development should not harm, and where possible should make a positive contribution to, the characteristics and composition of the strategic views and their landmark elements. It 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.
B 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.
C Development proposals 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 Townscape or River Prospect, and well preserved within its setting with clear sky behind it, 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 landmark should take into account the effects of distance and atmospheric or seasonal changes.
D In addition to the above, new development in designated views should comply with the following:
a 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.
b 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.
c 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.
E Viewing places should be accessible and managed so that they enhance people’s experience of the view.
F In addition to the above, where there is a protected vista:
a development that exceeds the threshold height of a landmark viewing corridor should be refused
b 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
c 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.
G In complying with the above, new development should not cause negative or undesirable local urban design outcomes.
H The Mayor will identify, in some designated views, situations where the silhouette of a World Heritage Site, or part of a World Heritage Site, should be protected.
J Boroughs should reflect the principles of this policy and include all designated views, including the protected vistas, into their Local Development Frameworks. Boroughs may also wish to use the principles of this policy for the designation and management of local views
7.42 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.
7.43 In complying with the requirements of Policies 7.11 and 7.12 development should comply with other policies in this chapter and should not have a negative effect on the surrounding land by way of architecture or relationship with the public realm.
7.44 Protected vistas will be developed in consultation with the Secretary of State. The Mayor will seek the Secretary of State’s agreement to adopt protected vista directions that are in conformity with the London Plan policies and the London View Management Framework SPG.
