Swedish studio Claesson Koivisto Rune has unveiled a boutique hotel in Tokyo, featuring 24 new design products.K5 Tokyo occupies a converted bank building next to the Tokyo Stock Exchange, which survived bombing during the second world war.

Claesson Koivisto Rune's team adopted an "everything-is-possible attitude" to design and delivered the hotel in just 14 months.As well as overseeing the architecture and interior design, they designed all kinds of products, from a pencil to a bespoke Tokyobike.Studio co-founder Ola Rune said that K5 Tokyo is the best project they have ever worked on.

The design is based around the idea of "aimai", a Japanese word used to positively describe things that are ambiguous, obscure or vague. It inspired a layout where furniture, textiles and plants are used in place of walls, to create more subtle divisions.Contemporary details and furnishings help to brighten up the building's ageing but characterful interiors, while plants are intended to create the feeling of an urban oasis.

The hotel is organised over five levels. The ground floor and basement contain a series of spaces for eating, drinking and socialising, while bedrooms occupy the three upper floors.The most plant-filled space in the hotel is the Switch Coffee shop, which doubles as a florist. Just beyond is a wine bar and the Caveman restaurant, set against a backdrop of green, blue, pink and clear glass.Claesson Koivisto Rune created several furniture designs for these spaces, including a long sofa upholstered in deep red leather, a small wooden stool and a low coffee table.

Beds are framed by hand-dyed curtains, featuring a sky-like gradient of blue and white. These are hung in circles, framing just the bed and a custom paper lamp suspended overhead.A red "love seat" is positioned alongside a more generously sized sofa, in bright, contrasting colours. Larger rooms also feature a custom carpet manufactured by Kasthall in the style of a Japanese tatami mat.Bathrooms feature cedar wall panels, black sinks and tiled floors.
