About First Floor Exclusive Hire
400 Theatre
400 Standing / Reception
The First Floor Exclusive Hire transforms your event into something extraordinary, where scientific history meets celebration across six interconnected rooms. Picture your guests mingling beneath the same ornate ceilings where Nobel Prize winners once debated, their conversations flowing as freely as the champagne we'll serve from our fully licensed bars. Our Theatre commands attention with its dramatic semi-circular design and rich red seating for 400 guests. This isn't just any auditorium, it's where groundbreaking discoveries were first announced to the world, and now it's ready for your product launch, awards ceremony, or conference keynote. The acoustics, perfected over centuries, mean every word carries beautifully to the back row. Through the adjoining doors, the Library offers a complete change of pace. Floor-to-ceiling bookshelves frame tall windows that pour daylight across soft blue walls, while crystal chandeliers add evening sparkle. We often see guests gravitating here during drinks receptions, drawn by the intimate atmosphere and the kind of authentic character you can't manufacture. The Writing Room and Georgian Room maintain the elegant momentum with their period features and plush carpeting, perfect for VIP areas or quieter conversations during larger events. Meanwhile, our Demonstration Room bridges old and new, where original scientific equipment displays share space with cutting-edge AV technology, projectors, flatscreen TVs, and a full PA system ready for your presentations or interactive sessions. Searcy's, our in-house caterers, know these spaces inside out, timing service perfectly whether you're hosting formal dining or flowing canapés. Getting here couldn't be simpler, with Green Park Station just minutes away, plus that rarity in Mayfair: actual parking spaces. Your celebration deserves more than bland hotel function rooms. Here, every detail tells a story worth sharing.
