Plenty of stuff in the Eureka market scene, bowls, baskets etc. Wooden jewellery beads work well as jars.
I’d say there are two things that make a village for the period, a well and family bunkers.
The wells came in a variety of types naturally enough but round concrete or packed clay seem the most popular. Bunkers could be built under the hootches so largely invisible but just as common for them to be next to them. A sort of raised hummock with an entrance, somewhat like a small Saxon burial mound describes a typical one.
There can also be a bit of variety in buildings, you might expect a village headman to have a slightly posher or bigger abode. At the other end the spectrum due to destruction, re-location and just general thriftiness you might expect to find shacks made with varying bits of Allied detritus and more contemporary building materials, CGI, plywood, wooden packing cases, plastic sheeting etc. Nearer bases and at the edge of urban areas there are even examples of shacks made almost entirely from flattened beer and soft drink cans.
You can have heaps of fun with Vietnamese village building. I’ve incorporated corrugated iron sheets and scattered things like mattocks, bead jars and the like around the bases of my buildings. You should also think about putting in small gardens and the inevitable livestock around them.
