KNOWN SOURCE TAKES OVER MAYFAIR WITH A CHARMING NEW HQ


At the end of last month, vintage marketplace Known Source launched what is currently London’s largest-ever second hand fashion concept store named ‘Known Source HQ’.
Known Source HQ takes the shape of a five-story townhouse located at 35 Brook Street in Mayfair. Home to thousands of unique and archival pieces, the store will act as both a retail space and double as a multi-functional activation hub, coworking space and creative studio.














Founded by Henry McNeill-Njoku and Theo El-Kattan in 2022, Known Source has played a massive role in the status of second-hand clothing in our current cultural landscape. Being a digital home to a meticulously curated collective of amazing independent businesses, Known Source’s goal has always been to serve the fashion community at every angle.
“Known Source HQ is the next evolution of our community-led innovation. Trust is everything in our approach with our HQ, people will feel that with the products and the programming” – Henry McNeill-Njoku














Now, having a physical space just off Bond Street and a short walk from the heart of Soho, Known Source HQ will feature a selection of one-of-a-kind treasures from household name designer brands to specialist activewear to streetwear culture staples.
The space comes as the company’s second store as part of Westminster City Council’s Meanwhile On project which aims to give outstanding brands access to impressive and modern retail spaces.
“There’s a real need for a physical space in London where creatives from different pockets of society can come together. We’re dedicated to showcasing and bringing together the second-hand subculture.” – Theo El-Kattan
