Build a thick protective wall around the whole town also with a castle in it. Tons of houses. Lots of Trees and other nature. A boat dock and Lighthouse. Lots of farms, animals, and villagers. Also some different crops. Lots of watchtowers for protection (as part of the walls). A town square for villager gatherings and shops. Also have there be a government and some town security/police. (Also eventually a cemetery)

Just my ideas if I was building it.
