It would be good if there were more detailed building plans / schematics / pictures in the Ufopedia for base buildings. In particular, the above ground bits. This will help when planning the placement of buildings, to have clear fields of fire above ground for base defence missions. For example, I like to build my radar building near the entrance and dropship hangar so I can send a sniper up the tower to snipe aliens on the surface. It helps to know which buildings have low roofs so I can put them around the radar building and not block the enfilade fire from it.
