Located in the Shinjuku 新宿区  district of Tokyo Stuart Forbes worked on this project whilst at Rogers Stirk Harbour + Partners : address オアシス21ビル. The building won a RIBA International Award in 1993
Twelve stories of office space from this building. The buildings roof is hung off the main structure with a lift and staircase in a core together to one side. The building received the RIBA International Award.

The  Kabuki-Cho  project  was  Stuart’s first building project for RRP and it opened a deep routed fascination with technology and expression of form which remains a consistent theme today in the work of Stuart Forbes Associates.

The  project  provides  a  vivid example of a response to a very specific urban context; an area of  small - scale  streets  close  to  Shinjuku commercial district. The site was extremely constrained with daylight a precious commodity in the narrow road onto which the building fronts. Although the building is small in scale great attention was paid to the detailing of the façade using repetitive functional elements to define the lightweight language of the building.

The final scheme (after the abandonment of initial plans for a hotel) was a twelve-storey office building (two floors below ground level), its main floors canted out over a void which is infilled with a dramatic glazed roof, lighting a public basement area which contains restaurants and bars.

The roof is hung from the main structure. The frame, engineered in line with local fire safety and seismic protection regulations, is a composite structure of steel and concrete. As usual, lift, stairs and other services are concentrated in a strongly modeled tower, which terminates in a viewing platform above a penthouse apartment.

オアシス21ビル has been beautifully engineered for the client K-One Corporation. The core structure of concrete and streel meets all the local regulations to do with withstanding local eatherwuakes. 
Shinjuku 新宿区 - This office maximises the natural light by creating a large atrium to bring light into all the lower office floors. 
The fire escape staircase. Made of steel and tensioned with cables.
The street facade of the building. Kabuki-Cho Tokyo Japan making the most of the precious comodity that is daylight. 
This building used 3D modelling to design and work out the complex structure used to hold up the glass roof.
