Many years ago I read about mini-warehouses. I had a small piece of commercial property, and I thought it might be a good idea to build a small structure with a few mini-warehouses to rent. I worded the ad in the newspaper wrong, and instead of getting inquiries about mini-warehouses, I got phone calls from people wanting to rent mini-workshops. IOW, there were lots of people who needed a small workspace with electricity and access to a bathroom or running water. I thereby realized that there was a market for that sort of thing that was not being met, and I changed my plans. Instead of building mini-warehouses, I began building mini-workshops. These spaces are needed by artists, people who want to work on their hobbies, people who need a small retail sales place, people who need to move their businesses out of their home but don;t want to pay a lot of rent, etc. This need exists everywhere, but very few investors are taking advantage of it. In China investors build long one and two-story buildings that are divided up into single car garage workshops, double car workshops, workshops with an apartment above them, etc. In America the mini-warehouse niche has been filled, and there are millions of mini-warehouses for rent, but the workshop niche has not yet been filled. I would suggest that investors consider that to be a huge opportunity. The trick is learning how to build such spaces economically and in such a way that the structures cannot be easily damaged.
