I suggest this- Kin leader will have option to set up new hood, name as you want, for some cost probably... (Gold, or real money, mithril, turb.points??), and this hoods will have new structure, in middle will stand kin house, around, f.e. in circle, then will creates houses which type member of the kin choose (standart-deluxe) and type of house too (elf, hobbit...), and first circle will have f.e. 10 houses, and then will be create new bigger circle... Hood doesnt have exact number of houses, it will depend on, how many members will buy one, in fact, hood could have as many houses as many members have...
Sorry for my english:-)
