“Inside the Waterfall” is a project that combines the harmony of nature with contemporary design. The circular-shaped building creates the illusion of living inside a waterfall through the use of reflective materials and light effects. When it rains, the roof channels water onto the glass walls, creating cascades on both sides. The exterior features glass walls and polished metal, which reflect natural light and recreate the effect of a moving waterfall even in the absence of rain. The circular shape is emphasized by the absence of windows along the vertical walls, enhancing the sense of privacy and protection, as if surrounded by a natural water barrier. Windows are placed exclusively on the roof, a distinctive element of the concept. These openings frame the sky, offering a privileged view of the celestial environment and creating a deep connection with the universe above the house.

During the day, sunlight enters from above, flooding the interiors with natural light without interrupting the visual continuity of the circular walls. At night, especially in the bedrooms, these windows allow for stargazing, offering a contemplative and evocative experience. Sleeping under a starry sky, framed by the perfect geometry of the rooftop windows, creates a unique emotional connection with nature. The interiors follow soft, fluid lines, evoking the movement of water. The spaces unfold in continuous curves, creating a natural flow. The light entering from above enhances the sense of openness and spaciousness, while the glossy surfaces reflect natural light effects, accentuating the dynamic atmosphere. The selected materials—glass, steel, and natural stone—are carefully chosen to enhance light reflection and luminous effects.


The interior finishes feature reflective surfaces, amplifying daylight brightness and creating a warm and welcoming atmosphere in the evening hours. Living in the Circular Villa Inside the Waterfall means experiencing a deep connection with nature, not only through the visual illusion of a waterfall but also through the constant view of the sky.

The rooftop windows not only provide a spectacular view during the day but also transform the house into a private observatory for stargazing, making the nights a moment of intimacy with the universe. This project pushes architecture beyond conventional boundaries, blending nature, design, and technology. Through the innovative use of rooftop windows, the concept not only recreates the illusion of a waterfall but also offers an immersive living experience that celebrates the sky and the stars, inviting residents to live in harmony with natural and cosmic rhythms.
