In 1985 LOGID designed the extension of an administration building. This GSA project saves energy and provides imaginative offices and work areas, but construction costs did not exceed those of conventional architecture. Forty working places were installed in the glasshouse by staggering two wooden pavilions one on top of the other. The glasshouse contains plants and serves as a conference and recreation area. The plants are subtropic species requiring a temperature of 5° Celsius in winter. They serve not only as decorations, but provide dust-free air containing ample oxygen. Their fruits an scent make for a pleasant working atmosphere.
