The picture shows a modern residential complex with several white, multi-storey residential buildings standing on the left and right side of a paved path. The buildings have balconies with dark railings, and some balconies are decorated with plants and furniture. A wide, paved footpath stretches between the buildings and continues into the distance. On the left side of the path are lush green areas and colourful flowerbeds that embellish the space between the buildings. On the right-hand side of the path, young trees are planted at regular intervals, forming a green avenue together with manicured lawns. Other buildings can be seen in the background, completing the urban surroundings of the residential complex. The sky is clear and blue, indicating a sunny day.
