The average British company uses only 55 per cent of tts office space and two-thirds of employees are unhappy with their work environment, according to a survey recently undertaken by the design consultancy Best Desks Ltd. This inefficient use of space equates to over ten billion pounds of waste in London alone. The advent of wireless technology means that employees no longer need to be tied to fixed workstations with wires and cables and can work more flexibly. Trend forecasters predict the following mnovations to workspaces over the next decade: more collaborative, open- plan spaces to encourage social networking; reservable mobile workstations; easily interlockable office furniture; and bespoke ambient sound and lighting.
