a cutting-edge residential apartment building with a penthouse, situated in the heart of a metropolitan city (Lagos). The design should emphasize floor-to-ceiling windows that offer panoramic views of the skyline, an open-concept living space, and ultra-modern amenities such as a rooftop infinity pool, a private gym, and smart home integration. Rich materials like marble, glass, and polished steel should be used throughout, enhancing the sense of luxury and sophistication.
