​I own a building and want to make it profitable

Hello,

I’ve been working in a coworking space for some time now in a three-story building located in the downtown area of a city with 30,000 residents within the city limits (and 100,000 residents in total).

This building has a 40-square-meter ground floor, three open-plan floors ranging from 30 to 50 square meters, two meeting rooms, and four offices ranging from 13 to 20 square meters. There is also a large 150-square-meter event hall and over 200 square meters of unoccupied space.

Today, these spaces are almost empty (I’m often alone, and at most there are 4 people during the day).

Originally, this place was a startup incubator; it still is, but it’s becoming less and less active.

The building looks a bit old, so it doesn’t attract many people.

The owner is almost never there because he’s retired (and enjoying his wealth).

When I see this, I want to make the most of this place’s potential.

Do you have any ideas on how to make it profitable?
