If you simply want to use the static buildings from the object list to populate a custom village, and it's not for an MA terrain. You gents have always been free to create them. It's time consuming laying down one object at a time. You can create several villages on a test terrain and save them as group objects to be reused. Unless you follow Easyscor's advice and create a custom tile set or a custom object like the town object, you will have no way to paint in streets. Maybe use the new path function and lay down a "view only" street grid then populate your building objects. The view only road objects would not be saved if you saved the village as a group object when you were finished.
Time is the biggest hurdle and I've had a lot of experience with how much time it takes lately to populate MA terrains with static road systems and extra objects aside from fields, ports, vbases, and strats. I just got done updating Oceania with supply paths after submitting riftval back with fixes for terrain and river\road issues that were getting worked out by Hitech.
Devil you can use the skin viewer to look at the building objects available to do something like this. If you can get someone to help you setup a small test terrain with one airfield so you can up on it offline only. Easyscor and the crew here can get you up to speed enough that you can play with combinations of the available building objects to create villages. I suspect the width of a view only road path and a few buffer feet will be the separation you will need for the building objects. It does look like there are a group of buildings designed to be placed together to create court yards though. You can paint down a village from the Euro terrain set and measure Waffle's placements as a benchmark.
Once you have something you like, highlight that whole area and save as a group object to be reused on the SEA terrain you want to update. The benefit is you can rotate that object group's orientation 360 while a square object like a town can only be rotated four directions.
I can always zip up a copy of my test terrain for you so you have something to start with. It will have all the tests I did for riftval on it but, you will have those to monkey with to see what happens. It's painted with the Med tile set so flipping the menu selection to the Euro tile set should be entertaining and instructive for the outcomes.
