As part of my new responsibilities - I'm working on a system to keep track of all town members and their plots, so I'll know who has paid for extra space, what size plot each person should have, etc. I do think it's fair that people with larger plots should pay more taxes --- doesn't have to be a lot, but a little something extra. I'm not sure exactly what you mean Plasma about buying out existing owners...
As for the plot sizes -- I propose that there be 3 tiers of plots...
12x12 -- free initial plot, or if J3sus wants to charge 20c - that's cool too. Taxes @ 15 (when they go back up)
18x18 -- an extra 200c for the initial purchase, and extra 5c a week in taxes (when taxes go back up to 15)
24x24 -- an extra 500c for the initial purchase, and extra 10c a week in taxes (when taxes go back up to 15)
Basically, we want to give people the option to expand their plots, but because space is relatively limited (moreso as we get more members), we need to make it somewhat expensive to do so. The 3 tiers could be 12x12, 16x16, and 20x20 also if you feel the suggested sizes above are too large.
Once I get the OK from J3sus on the plan, I'll go ahead and put everyone down in my spreadsheet and begin keeping track. J3sus: if you want me to basically keep track of the "extra" taxes - I could collect those separately and remit the taxes to you. Let me know your thoughts on how you want to handle that.
Finally, all plots will be subject to approval by an architect, officer, or Toad or j3sus - for example, there are some current plots where expanding to 24x24 (or 20x20) would interfere with basic town infrastructure or other houses.
