Kosher facilities are among a list of requests from Finchley residents campaigning for a stately home and park to become more accessible to the community.
Avenue House currently provides facilities for weddings and conferences but residents are writing to its trust to ask for a new kitchen to be set up for kosher catering.
More than 50 families are involved in the campaign and organisers hope another 300 people will sign up.
"The demographic of the area is primarily Jewish," said Jason Lurie, one of the campaign leaders.
