Here’s an alternate layout, from dividing a 900m area into three parts.  Cozy, isn’t it?  Our rowhouses from earlier are 400sqm (4,300 sqft), so we can double up on them (as in the middle) without too much trouble.

But this might be too small.  We wanted to adequately secure our village nestled in the city so that suburbanites would move to it, but this area isn’t large enough to be comfortable chilling in with edge friction, and outsiders will likely walk right through it frequently.  This doesn’t get us enough edge on driving down bleedover crime from the commercial areas on the mixed-use outer ring.  It does look pretty, though.
