A photo-realistic rendering of a modern, contemporary building with a contemporary design, located on a rooftop at dusk. the building is a two-story, rectangular structure with large glass windows that allow natural light to filter through, creating a bright and airy atmosphere. the exterior of the building features a staircase leading up to the second floor, which is surrounded by a well-manicured garden with trees and shrubs. the sky is a deep blue with a few clouds scattered across it, and the cityscape below is visible in the distance. the lighting is soft and warm, casting gentle shadows on the building's exterior. the overall aesthetic of the image is sleek and contemporary, with a focus on the natural beauty of the architecture.
