This is because the walls, gatehouse, generic buildings etc are all the same model, the individual buildings that feature in the tech tree are seperate models which are included based on whats in the actual strat map settlement. You cant place walls because there are no individual wall pieces, just the settlement as a whole.

The file structure for both the tech tree buildings and the settlements themselves look to be pretty much the same, if one gets cracked the other should be too. They're more complex though than units so its not going to be done overnght.
