The palette consists of traditional materials such as concrete, cedarwood and Japanese stucco. Complemented by a wide range of furniture and accessories, custom designed by Claesson Koivisto Rune.
Housed in a converted 1920s bank building,
K5 Tokyo sits beside the Tokyo Stock Exchange and connects the traditional Imperial Palace area with the hip Eastern part of the city. The Japanese word ‘Aimai’ guides K5 Tokyo’s concept, which translates to vague, obscure or ambiguous. The Japanese word has a positive, poetic sentiment, denoting the benefits of erasing borders.
Spread over 2,200square metres across 4 levels, this mixed-use project comprises a hotel, restaurant, wine bar, coffee shop, cocktail bar & beer hall. Designed by Stockholm-based architects Claesson Koivisto Rune, K5 Tokyo’s functions intentionally intermingle – the library is the bar, while the coffee shop doubles as a lounge, which flows into a wine bar and restaurant.
Claesson Koivisto Rune tackled the revamp with gusto, committing full respect to the original features of the building. Original raw concrete flooring is augmented with newer floor coverings honed from the same material, while the presence of traditional accents, such as cedarwood and Japanese stucco, maintain a mood of authenticity and connectivity to the structure’s past.
Guided by ‘Aimai’ as a design concept, Claesson Koivisto Rune implemented a fluid spatial mood where unclear boundaries lend themselves to versatile areas that have the capacity to change character throughout the day. This is best experienced in public areas like the reception, which duals as a coffee shop that gently seeps into the wine bar and then the restaurant.
The hotel’s unique location has directly influenced the lighting and colour scheme in some public spaces. With the rear of the hotel facing an arterial thoroughfare, Claesson Koivisto Rune have utilized passing car lights as a feature, incorporating coloured glass into all windows at the back of the hotel for a kaleidoscopic light show in the hotel’s corridors.
