Architecture steps into London Pride with Proudspeaker, a sculptural float and mobile installation that transforms protest into performance.

Founded by Rania Francis, Karl Mok and Oleg Sevelkov, oo office is a London-based architecture and research practice working at the intersection of cultural narratives and material experimentation. With Proudspeaker, the studio proposes a monumental megaphone – ‘a collective exhale’ - that amplifies LGBTQIA+ voices and stories in public space.

“The form of the Proudspeaker is composed of individual stories, gathered and woven together in a magpie-like process,” says the team. “It becomes speech made visible - an act of joy, pride and protest.”

Conceived through the lens of a queer migrant - a story woven deep into London’s ever-evolving multicultural mosaic - Proudspeaker answers the call of the London Festival of Architecture’s 2025 theme, Voices. Part canopy, part sanctuary, it stands as a bold gesture of solidarity across the full spectrum of the queer family.

Draped in a 9-by-9 metre quilt stitched together by over 20 volunteers, it carries hundreds of messages in global languages - some of these are memorials, others might be tender love poems - all woven into a tapestry of lived experiences. Proudspeaker speaks to highlight the fragility of LGBTQ+ rights worldwide, and the unshakeable strength found in chosen families.

“Architecture doesn’t just shape our buildings - it shapes our communities, our conversations, and our sense of belonging,” says Rosa Rogina, Director of LFA. “Proudspeaker is a defiant, joyful and beautifully conceived response to our 2025 theme. It honours queer creativity and boldly asserts that LGBTQIA+ voices not only belong in the built environment - they are fundamental to it.”

The float is supported by the London Festival of Architecture, Architecture LGBT+, Freehold, Brookfield Properties and Eastern City BID.
