Traditionally the office has been seen as the physical space within four walls which doesn't extend beyond that. With an elastic office, that's no longer the case. A company can have an office smaller than their requirements in square feet. When they need a space outside of their four walls, they can get it on-demand with the help of space providers like Convene. As a result, a company can fluctuate in size, getting bigger and coming back down to size as needed (hence "elastic").
