Sea-Dar converted this 5-story private home into an artful blend of romantic, 19th-century ambiance with modern elegance and conveniences. Situated at the heart of the home is an interior winding stairway encased in stainless steel cable with glass panels and a wood bar railing that connects all 5 stories. The view from the top down the hollow middle of the stairway is dramatic with repeating steel and wood lines outlining the concentric path to the bottom.
