Create an architectural design for a modern 5-star hotel located in the heart of a bustling city with high commercial activity and heavy vehicular traffic. The hotel should feature an elegant, sleek exterior with glass facades, contemporary lines, and luxury finishes. It should offer a high-end experience with spacious, well-lit lobbies, a large reception area, and state-of-the-art amenities. Include multiple floors with luxurious rooms and suites, an executive lounge, fine dining restaurants, a spa and wellness center, and a rooftop bar with stunning views of the city skyline. Ensure the design incorporates ample parking for guests, underground or multi-level parking options, and efficient traffic flow for easy access. The interior should showcase premium materials, modern furnishings, and smart technology for guest comfort and convenience. Include a grand, well-maintained entrance, with a spacious driveway for drop-offs, and wide glass windows to provide a sense of openness. The hotel should be designed with sustainability in mind, incorporating green building technologies, energy-efficient systems, and a rainwater collection system for the landscaping. The facade and interiors should convey a sense of luxury and modernity, with a strong focus on quality, style, and environmental responsibility.
