Yeah, if I had Mel Gibson-like money, I'd be doing Traditional Catholic community development all over the place (I'm not a huge fan of SSPX right now). I would also work to make the communities as grid-independent as possible, and would plan it out so that every few homes could share resources. In my neighborhood and in most neighborhoods, there's a huge amount of waste. So, for instance, every person in this neighborhood has their own equipment (lawn mowers, riding mowers, trimmers, edgers, car tools, power washers, snow blowers, etc.) ... when, what?, many of these tools you use maybe once a week? There could be a little tool shed every few homes (situated close enough to them all) so that these could be shared.
I would also build/sell the homes for no profit and finance at 0% interest (maybe some fees just to manage it all). There would be a Home Owners Association, and violators of rules such as modesty of dress, public cursing, etc. ... would receive fines, with multiple serious infractions resulting in eviction.
Every few homes would have a little mini-park area with swing sets and other things so the kids could play (again, shared so that each home doesn't need a swing set), and then there might be some facilities like gyms (gender-segregated of course), perhaps a garage for people to work on their vehicles, a store, etc. ... so that the community could almost have its own little micro-economy. And of course there would be areas for farming, having livestock, etc. that could be commonly maintained.
And of course there would be a little chapel there where the Blessed Sacrament could be reserved for visits.
