OPs idea is very kind, but not very practical. There is wayyy too many small plots. Let's not pretend that while yes, many people are happy with their small plots, there is also quite few small plot owners who would prefer medium, or large, and supply is keeping them from owning the preferred plot.

To some people the yard and the garden is big thing. And I personally enjoy taking walk around random ward to see peoples houses (if they're open). Neatly put garden and yard is eyecatcher.

I think I'd just take apartment update instead.
