Renata Hamvas (fellow Labour Councillor for Peckham Rye) has just called with some news. She's just posted this on local forums:
"Thank you for the many many emails I've received about the Ivyhouse, you have been keeping me very busy over the last couple of days! Just to update on the situation:
I have been liasing with English Heritage over the Ivyhouse and as of today, The Ivyhouse is a Grade II Listed building. The owners have been notified in writing of the change in status of the building.
