Those look very strange. Everything below is my own interpretation - wearing a big black hat to focus on what you can improve.
The lighting effects should be much more subtle, as Zarel imagined, they look too distracting. They also need more logical connections with real construction materials - Baseplates would be pretty much like a "radier" type foundation, probably mixed with augercast type piles for a blended shallow/deep foundation - pretty common in industrial buildings, like automobile factories.
Those are 99% of the times made with concrete, and if made in tiles, those would be very large, probably something ranging between 2x2 and 5x5 meters.
Also, the striped lines are often used as a symbol of isolation, or warning. Those should be near electric transformers, robotic arms, explosive materials, or anything like that, not around a whole building. What you are probably trying to depict is a "location" (I don't know if that's the correct translation), which is a representation of where certain walls, gates, windows, reservoirs, circulation areas, or even whole blocks, are going to be constructued according to the blueprints - it is a measurement procedure where you use coordinates of the terrain to mark corners and lines and stuff like that to make execution easier, afterwards. It is also used to show that "something will be built here afterwards, so this space is reserved".
Those are hardly dangerous areas - they should be clearly visible but shouldn't be yelling "go away", like yellow+black, yellow+red or black+red patterns overall do. You should stick to one color, and, if you're making teamcolored parts in the baseplates (which I reccommend as well, structures should indeed be more teamcolored), this color needs to be neutral. Like, for example, white, or, if a more subtle tone works out and doesn't look like the building is owned by the yellow player, yellow is also acceptable.
Also, most of the buildings in warzone are probably meant to be partially underground - therefore, I'd reccommend that you represented ventilation outlets and inlets (inlets should be on the structure itself preferrably, since the air is going through the building, is going to be heaten, and probably will be partially transformed in carbon dioxide, and therefore will be lighter, going up, making higher outlets more effective than lower ones, which would need mechanisms to provide a flux).
As you see, most of my advice comes from real structures designing, and since I'm going through a civil construction course for 4 years now, I have a keen eye for such logical needs of structures overall. I would ideally suggest that you made full blueprints of the buildings (since you don't have to care about 90% of the designs, like hidraulic systems, structural calculations, execution planning, area usage/circulation ratios, sewer systems, or even ventilation systems, making such blueprints would be very fun and quick to do), but that's probably too much to ask for
Now I've got to sleep, got Soil Mechanics and Concrete Technology classes tomorrow
And it's 3:34 AM here right now
I hope it doesn't sound too harsh, but that all really comes into play if we are aiming for high standards, and not
lame partially incoherent, "don't think too much about it or you'll hate it" designs. That carefulness with design makes everything a hundred times more beautiful to the trained-eye users.

They feel like they would be too distracting, in-game. Baseplates are a good place for teamcolor; maybe we should try working that in, instead? And also decontrast like a ton.
