In London there are planning laws that disallow tall structures from impeding on certain views, and vantage points of iconic buildings. The most iconic building in London — and therefore the most protected sight-wise — is St Paul's Cathedral.
St Paul's is the primary reason there is a cluster of skyscrapers in one part of the City of London. Generally, buildings nearer to the cathedral are lower too.
We sent Vicki Pipe to investigate some of these sightlines. Our favourite is where a hedge and line of trees in Richmond Park are trimmed back, specifically so that St Paul's can always been seen.
Thanks to the New London Architecture for letting us have exclusive access to their model.
