According to a previous article she feels that the bollards around the perimeter make it difficult for double buggy and wheelchair users to navigate the square. Apparently a survey revealed that what these inconvenienced users hoped might sort things out was for the square to be turned into an international tourist destination and filled with selfie taking tourists.
I don't think you and her are going to arrive at a mutually satisfyingly conclusion to this.
For my part I was reminiscing on the good old days.
former chair of the Community/Police Consultative Group for Lambeth and erstwhile member of the Independent Police Complaints Commission, used his middle-aged enthusiasm for planning rules successfully:
1 - to force Lambeth Council to remove the huge electronic display they had put on the Acre Lane side of the Town Hall steps. He also had a crack at them for altering the windows in Room 8 (now long gone). The Town Hall is apparently listed.
2 - in conjunction with the Friends of West Norwood Cemetery, contested Lambeth Council's plans to grass everything over and resell plots (from Wiki):
"Lambeth Council
compulsorily purchased the cemetery in 1965, and controversially extinguished past rights and claimed ownership over the existing graves. Lambeth changed some of the character of the grounds through "lawn conversion", removing at least 10,000 monuments (including some of the listed monuments) and restarted new burials, reselling existing plots for re-use.
Consistory Court cases fought in the
Southwark Diocese in 1995 and 1997 found this to be illegal. It brought about the cessation of new burials and forced the restoration of a handful of the damaged or removed monuments. In addition it required Lambeth to publish an index of cleared and resold plots, so that the descendants of historic owners can identify and request restitution of their family's plot.
[5] As a consequence of the courts' findings, Lambeth now operates the cemetery in accordance with a scheme of management under the joint control of all interested parties, that includes Lambeth, the Diocese, the Friends of West Norwood Cemetery and conservation bodies such as
Historic England."
Unfortunately Lambeth defeated Nick Long on Windrush Square. He marshalled his conservationist arguments (he had for years been a stalwart of the 20th Century Society).
Lambeth had an ace up their sleeve - the descendants of Sir Henry Tate were unwilling (in writing) to get involved in the Stalingrad Square argument, even though Lady Tate had gifted the land.
Just goes to show if you stick your head under the pillow and hope Lambeth will do a good job you end up with bollards on your lawn!
