Hi, this is a pack containing massive futuristic-like brutalist buildings. You can combine elements as you wish, since original four buildings are a composite of several building blocks, as you can see in the preview images.
Modeling was done in 3ds max 2023 with V-ray 6, so that software is recommendable for use, but I made sure you can use it in Blender as well. Feel free to ask me for any additional info, I would be happy to help.
