Hammersmith Tories are under fire for planning to concrete over part of a park while citing damage to the gardens as an objection against the Thames Water 'super-sewer'.
Hammersmith and Fulham Council proposals for redeveloping the town hall (pictured) include a bridge over the A4 to Furnival Gardens, Hammersmith.
They say the super-sewer planned to start in Furnival Gardens would damage the gardens, while their proposed bridge would be an 'improvement.'
But Hammersmith and Fulham Historic Buildings Group is against both ideas. Chairwoman Angela Dixon said: "We oppose the idea of a bridge with descent ramps into Furnival Gardens. This would damage the Town Hall and encroach on a very popular park.
"Furnival Gardens would be damaged, which is why we are opposing it. It would also loom over the lovely nest of buildings by the park including The Dove and Sussex House."
Mrs Dixon from St Peter's Square in Hammersmith believes the Thames Water sewer may be inevitable. She added: "Because of changes to planning laws, that may be imposed on us. But with the bridge there is a choice and it is the council's."
A council spokesman said the park would be not be harmed. He added: "We do not see this as damage at all, in fact it is a huge improvement. A lot of people have complained about traffic noise in Furnival Gardens and that is why a lot of these proposals we are talking about have an abutting bank of earth."
