Claesson Koivisto Rune Architects have converted a former 1920s bank building in Tokyo into what they describe as a "micro-complex of creative eateries, bars, gathering spots, and Swedish-minimalism-meets-Japanese-heritage design."

Located in the Nihonbashi Kabutocho area of the city, K5 Tokyo is a hotel with a restaurant, a wine bar, a coffee shop, a cocktail bar and a beer hall.

Its redevelopment took only 14 months from conception through planning and construction, ultimately creating 20 guest rooms, mostly around 40sq m (430sq ft) in size with a ‘Loft’ suite covering 78sq m (840sq ft).

The building retains its exterior architecture, which is described as Western neoclassical with Japanese detailing and proportions, while original elements of the interior – like exposed concrete and a parquet floor – were retained where possible.

Traditional materials such as concrete, cedarwood and Japanese stucco are complemented by custom-designed furniture and accessories.

A lack of greenery in the area, meanwhile, inspired the idea of creating a ‘green oasis’ in K5 Tokyo, with potted plants throughout contributing to a sense of wellness and softening some of the more stark design elements.
