Penthouse II is a minimalist space located in Rome, Italy, designed by Des Interior Architecture. The living area is open plan and is characterized by the Roman Navona travertine floor. The wall and roof are curved to accompany the eye of the observer toward the large windows that allow access to the terrace. The parabolic shape of the ceiling, like the sail on a ship, was inspired not only by the waves of the lake during the mistral but also the architectural works of the Neo-Expressionist masters architects. This is not a mere exercise in style but a solution to the problem of acoustics for the existing gable roof.
