SummaryStudio KO reimagines Paris's historic Bus Palladium nightclub into a five-star, 12-level boutique hotelThe architecture blends raw brutalist concrete with retro, rock-and-roll-inspired design accentsThirty-five soundproofed guest rooms feature acoustic cork cladding and bespoke vintage curiositiesHôtel Bus Palladium, situated in the heart of Paris' 9th arrondissement in the vibrant Pigalle neighborhood, represents the rebirth of a legendary 1960s nightclub into a five-star boutique hotel. Tasked with the reinvention, Paris-based architecture practice Studio KO undertook staggering structural ambitions, excavating 14 meters underground to transform the site into a 12-level complex, with four levels hidden below ground housing a 200-capacity club.The building's exterior honors its storied past with restraint; the club's original red neon sign illuminates a minimalist, sandblasted concrete façade featuring discreet geometric patterns that echo the original structure without directly imitating it. Ultimately, the property aims to become a modern-day equivalent to New York's Chelsea Hotel — a chic, welcoming and creatively promiscuous sanctuary for artists, musicians, and travelers alike.Inside the hotel, Studio KO balances the venue's hedonistic heritage with high-end hospitality by creating a cinematic, highly tactile and contrasting aesthetic. The public and private spaces feature a deliberate rawness, where brutalist elements like thick concrete walls and metal grating ceilings are softened by sensual, retro touches such as powder-pink carpeting, Lynchian red velvet drapery, and corduroy curtains that nod to the uniforms of 1970s road crews. Subtle, witty design choices further extend the musical metaphor throughout the property. Guests will notice light switches crafted to resemble vintage amplifiers and micro-perforated door handles that mimic the grilles of microphones, ensuring that the location's rock-and-roll DNA is felt in every architectural detail.The hotel's 35 uniquely configured rooms and suites continue this immersive design narrative, functioning as quiet, soundproofed retreats from the energetic nightlife downstairs. A signature design feature is the extensive use of cork cladding on the walls and headboards, which serves both as a playful nod to Marcel Proust's famous noise-canceling bedroom and as a visual reference to the acoustic treatments of 1960s recording studios. These raw textures are paired with vibrant, glass-enclosed bathrooms tiled entirely in electric Klein blue or dusty pink, complete with Hollywood-style mirrors. Curated by L'Œil de KO and local antiques dealers, each room is filled with bespoke curiosities - ranging from transparent bedside tables displaying stacked cassettes to modular vintage furniture - perfectly encapsulating the location's eccentric and impertinent spirit.Hôtel Bus Palladium6 Rue Pierre Fontaine,75009 Paris, France
