Fps Drops with lots of gameObjects

i have lots of buildings in my scene that consist of a cube and about 350 planes that have a light emmissive material on them, There is about a hundred buildings also, Is there anything i can do to reduce the fps drops whilst looking off into my scene. or just increase fps in general
Any help would be greatly apreciated

If the buildings won’t move you can activate Static Batching for all of them and it will give you a performance boost.
