Rector David Paton of St Botolph Without Bishopsgate has objected to the architect's revised planning application to build the mammoth 41-storey skyscraper.
According to Paton, the proposed scheme at 106-126 Bishopsgate by developer Heron International will cause 'potential damage to the foundations and fabric of the church building'.
In an objection letter dated 16 October, he continues to explain that the development, which was increased in height by four storeys in late September (AJ 13.09.05), will also prompt 'loss of light' to the church building.
Paton first wrote to the Corporation of London to object to the scheme when KPF lodged its original application earlier this year.
There has been a church on the St Botolph's site since the 12th century. The most recent church was rebuilt in 1725-28 to a design by James Gould.
