I really don't care what size house a player owns. I would like to see a way to upgrade though. If the plots were all made the same size but allow any size house it would let people upsize/downsize the dwelling as desired. Since a small house has a small footprint you could allow more space for gardening or other outside things based on building size. It would add a bit of give and take to your dwelling size decision which I think would be good.
