The Detroit Works Project may be back on. One of the challenges of consolidating Detroit's neighborhoods is the question of what to do with all of that extra space that is left over once residents are relocated out of the less dense parts of Detroit. Quite frankly, whatever emerges will likely be a collection of several different options, all of which are still to be determined.
Of course, Detroit isn't the only place to have ever faced such questions. In Europe, there were villages that were largely depopulated. One of the solutions that they developed is to make it possible to rent an entire village.
Most of those who take advantage of this option are large corporations who use it to host retreats and other events. Those renting these villages will rename streets, incorporate their logo into the scenery, and do other things that simply are not possible in an ordinary hotel or convention center.
Something similar to this could be done in one of the depopulated parts of Detroit. It would require a considerable amount of investment to upgrade the housing stock and other infrastructure. However, the revenue from such a move could justify the expense to an investor.
This is just one of the many things that are possible as Detroit considers its future.
