By encouraging employees from the service sector to work from home (whenever they are only required to work on their computers), the need for office space is reduced to internal and client meetings.
If this happened at a large scale, the need for office space would finally decrease and more space could be allocated towards apartments, partially solving the housing crisis that certain cities and towns are facing. All sorts of properties could be created from former offices (from small studios to luxury city apartments)
With less need to travel to the office, peak time in transport would be reduced and a better service could be offered throughout the day. People working from home would be travelling in the middle of the day instead (e.g. for meetings). With high quality wifi, sockets and comfortable seats, travelling would become a proper part of someone's working time.
This is a vicious circle. Who will start first then?
