This is a project to convert office buildings that have stood in the center of Tokyo for 39 years to SOHO-compatible rental apartments. By newly adding residential functions to buildings that have receded from the urban front line as offices, the aim is not only to improve their property value but also to recycle them as part of an attractive urban landscape.
On the exterior, balconies that combine emergency escape routes with spaces for outdoor air conditioners are incorporated with a deep frame design using metal, thus transforming the image of the office building. Residential units are given unsuspended ceilings that make use of the existing floor height, producing combined working-living residential spaces that present proposals for new urban lifestyles. Among others, these include compact water facilities treated as part of the interior design, and shower units fitted as a standard.
The business of office conversion has only just started, in response to contemporary social trends towards urban revival, effective use of resources and, moreover, an oversupply of office buildings. This project not only organizes methods for technical solutions and economic infrastructure, but is also a pioneering example of compatibility with the SOHO style in urban relocation. As such, it is seen as a prototype for office conversion.
