A photo-realistic rendering of a modern, empty indoor space with concrete walls and floor, showcasing the interior of a building with large glass doors that have the word "smart" written on them in white letters. the doors are closed, and the floor is made of light-colored tiles. on the right side of the image, there is a red wall with the same word written on it, and on the left side, there are two red doors that also have the same text. the image is taken from a wide angle, looking down on the entrance of the building. the lighting is bright and natural, casting shadows on the concrete floor and walls, creating a sense of depth and dimension. the overall atmosphere of the space is clean and minimalistic, with no other objects or decorations in sight.
