Interior architect Irina Kromayer has overseen the design of Berlin's Chateau Royal hotel, creating a series of eclectic spaces that reference the heyday of the German capital at the turn of the 20th century.

The 93-room Chateau Royal is located in the heart of Mitte, on a street parallel to Unter den Linden boulevard and close to the iconic Brandenburg Gate.The hotel comprises two buildings dating from 1850 and 1910, as well as a newer building and roof extension designed by David Chipperfield Architects.

The renovation project, led by Kromayer with support from Swiss architect Etienne Descloux and interior designer Katariina Minits, aims to reflect the periods during which the heritage-listed buildings were constructed.Oak panelling, art nouveau tiles, sisal carpets and hardware in brass and nickel were incorporated into the scheme based on the finishings commonly found in Berlin's historic buildings.

The pendant lights for the guest rooms were created in collaboration with Berlin-based manufacturer Loupiotte and are intended to emphasise the building's high ceilings.Made from Japanese paper and brass, the lamps are based on a 1920s design from Josef Hoffmann, one of the co-founders of the Wiener Werkstatte art movement.

Built-in joinery found in each of the bedrooms was informed by the partition walls with integrated storage,which are typical of traditional West Berlin apartments.Paintings by early 20th-century artists associated with the expressionist and new objectivity movements influenced the hotel's bold colour scheme, which is applied across surfaces including tiles and upholstery textiles, along with curated artworks.

The interior features colourful glazed bricks and tiles similar to those found in Berlin's underground stations, as well as stained glass and coloured marble.Alongside its guest rooms, which include 13 suites and an apartment, Chateau Royal also accommodates a lobby, bar, restaurant, private dining room, fireside lounge and winter garden.

The hotel's restaurant, called Dottir, features upholstered oak seating by Bauhaus designer Erich Dieckmann.Artworks including a neon piece by Karl Holmqvist bring character to the ground-floor eatery.
