So the apartments and FC rooms, make it to where you can pay to upgrade them to house sizes and allow gardens to be placed inside maybe as a different furniture

Make upgrading a bit cheaper for FC houses to incentivize joining FCs.

It would be lighter than creating whole wards.

With less demand for houses they could up the time it takes for auto Demo from 45 days to 5 months if not get rid of auto demo all together. (This is a self serving suggestion though)
