Housing Plot upgrade, is it still in the works

[Dustytome]

And even if that did happen, what about when a plot is relinquished/demolished... would it revert back to the original size or would we be left with wards full of nothing but expensive large houses?

I image the plots would all be large sized and the house itself would just expand with that type of setup. As you said though, it's not realistic for them to redo the current housing wards for this.
