London mayor Ken Livingstone is set to radically shake up the rules governing historic sight lines in the capital.
The number of 'designated views of strategic importance' planners will have to take into account will increase from nine to 26, but they will be narrowed severely to lessen their impact on development opportunities.
The draft supplementary planning guidance (SPG) - which was drawn up by specialist planning consultants Miller Hare and the Richard Coleman Consultancy - will include special Thames-side strategic views for the first time.
Richard Coleman said the new document recognises the need expressed in the London Plan for development to intensify and for there to be an increase in the number of tall buildings.
'The draft guidance balances the need for London to intensify as a world city, and our responsibility to manage development so that important panoramas, views of national importance and key vistas remain for the enjoyment of all, ' he said.
'The SPG gives clarity to developers, architects and planners on what development will be acceptable and where, ' Coleman added.
This draft SPG provides guidance on the policies in the London Plan and proposes to update the regional guidance in RPG3a, dated 1991.
