Multiplex Revenue

I have an idea in my head that may help society a little bit. What I would do is multiplex a school building so it is partitioned into apartments and a school. The building would be bigger than the original school building but the school itself would remain the same size. The two areas would be physically isolated and it would be possible for tenants and students to be oblivious that other is present. 

The tenants in the flats would pay cheap rent, the profit from their rent payments would support some of the costs of the public sector like police and teacher's wages. The building would have solar panels on the roof so it would get power from sunlight and sell the surplus power back to the grid so it would also be carbon negative. The premises of a school would have many uses, it would help the environment, collect rent revenue from tenants, it would slow down the inflation in living costs because the demand for appartments would drop down and it would also be a place to teach young people essential skills.
