LGBT charity Queercircle plans to open a dedicated cultural venue on the Greenwich Peninsula in January 2022.
It aims to fundraise £40,000 to open the new site in the Design District housing a gallery, library and project spaces, citing the loss of half of London's LGBTQ+ venues over the past decade.
The venue will offer an annual programme of physical and digital exhibitions, residencies and participation programmes.
Queercircle Founder Ashley Joiner said exploratory workshops had identified the need for a permanent cultural space for the LGBTQ+ community.
"We look to New York’s Leslie Lohman Gallery, Berlin’s Schwules Museum and Hong Kong’s Sunpride Foundation, and believe we deserve the same here in London.
"Having secured an affordable space, we hope to foster an ecology of artists, curators, writers, thinkers, community organisers, grassroots organisations and charities who collectively work together to build a stronger, more creative and collaborative community."
