Residents of Pimlico are very concerned by the threat to Dolphin Square from a development that plans to make significant alterations to the buildings and threatens the garden. They would welcome support in fighting this proposal - initially by signing their petition at Change.org:

The issue is of Westminster-wide concern because the increased density proposed, in what is already a high density development, is setting a dangerous precedent.
