The Jewish Vegetarian Society (JVS) has launched a crowdfunding campaign to raise GPB25,000 to create a community centre.
The charity is urging the public to help fund its plan to create an "amazing new space in the heart of Jewish London".
As a token of appreciation, donors will receive anything from a massage to a three-course vegan meal - depending on how much they contribute.
Every pound raised will be matched by an anonymous Jewish vegetarian philanthropist, while the charity will invest a further £25,000 from its funds.
