This remarkable three-story villa in Vienna sits atop a historic 19th-century building, seamlessly blending modern design with historical substance. The U-shaped rooftop extension offers expansive views, open perspectives, and generous outdoor spaces, including a rooftop garden with a pool and an orangery for multifunctional use.
The interior spans three levels, connected by vertical voids that enhance the sense of spaciousness. Public areas, such as the kitchen and lounge, occupy the lowest level, while private children’s rooms with en-suite bathrooms and galleries are situated in another wing. The middle floor includes an office and a wellness area with a sauna and terrace. The top level houses the master suite, featuring panoramic windows, a walk-in closet, and a rooftop terrace with a whirlpool.
The design emphasizes high-quality materials such as limestone, marble, and oak, complemented by a sleek Alucobond exterior. This project exemplifies precise planning and architectural harmony within an urban context.
