The room is a white space with a staircase and an archway. The archway is located at the end of the staircase, creating a sense of depth and dimension in the room

This model I made it with Blender. I made it with actual size reference. I include some file format (converted from Blender), texture, and also, I include the lighting setup on the Blender file. Hopefully you enjoy it. Or you can edit my model with your preference easily.

Please like and share if you enjoy it.
