Design a luxurious, ultra-modern six-story building on a city street, using high-end materials like polished granite, marble, and wood for a sleek, sophisticated finish. The exterior should feature large balconies and expansive windows on each level to maximize natural light. The lighting design should incorporate hidden LED strips for subtle, elegant illumination, as well as spotlights and recessed LED lights to enhance architectural details. The overall aesthetic should combine the richness of natural materials with the clean lines and high-end touches of modern design, creating a visually striking and elegant structure. Front view
