Twenty years since expanding into the building next door, the historic Basel hotel Les Trois Rois has unveiled a new look for the annex, courtesy of Herzog & de Meuron.

The Swiss architects overhauled the neoclassical 1903 Basler Kantonalbank building with bold, romantic colour and sinuous motifs that echo the original neoclassical façade.

Central to the refurbishment is the former ballroom, now a restaurant called Banks, with plush booths in each Art Nouveau window niche, overlooking the Rhine. Whimsical mirrored panels reflect light from new crystal chandeliers, and a surreal ceiling garden dangles over the central bar, designed for the space by artists Gerda Steiner and Jörg Lenzlinger. The architects also reconfigured a banquet hall as a flexible entertaining space with shimmering partitions, and the Japanese-inspired Seijaku bathhouse on the top floor, with a wood-panelled sauna and steam bath.

New open-plan suites in the building are now the most desirable at the hotel, featuring red-velour bedroom niches, mahogany-toned furniture and clean, curved dividers between bed, bath and dressing room. The largest extend along the riverfront façade, with dining rooms, vestibules and custom furnishings. The headquarters of the architects are less than a mile away, with the finest sights in Basel between them.
