The Penthouse @ AllBright Members' Club
Friday 20th September
22:00 - 02:00
24-26 Maddox St, London W1S 1PP

It would be reasonable to deem Mayfair our spiritual heartland, so we’re delighted to welcome you back to its familiar embrace for September’s soirée atop one of its characteristic townhouses.
As twilight surrenders to darkness, chart a course to Maddox Street, where an unassuming door serves as your gateway to an unlikely sixth-floor party loft, awash with unbridled revelry and like-hearted souls.
By day, a female-only members’ club. By night, an otherwise empty building, awaiting mischief. We’ve been tasked with supplying the mischief but, naturally, there’ll be an abundance of splendour too.
Clamber up its narrow, winding staircase and you’ll be rewarded with The Penthouse. It's a more stripped-back setting than we’re accustomed to; an almost blank canvas space, ready to be brought to life with fierce looks aplenty and our trademark high spirits.
Those still clutching onto the fast-fading summer will rejoice in the addition of an inviting, flower-adorned terrace amongst the rooftops of Mayfair. This month’s soirée, however, is our swan song to summer - time to shed the lightness of warmer nights, in favour of a more seductive plume of black feathers ahead of London’s most louche party months.

Our parties and members
Expect to drink, mingle and dance the night away with an eclectic ensemble of fellow good-timers. We may be fashion-forward and we may have a discerning disposition towards partying but, above all, we’re friendly and fun-loving.
We're not about elaborate productions or big-name DJ's, we’re about bringing great people together in exquisite and intimate venues. Our only policy when it comes to music is ‘does it make you want to dance?’. For the avoidance of doubt, we keep our clothes on!

See you on the dance floor!
