Studio Arthur Casas has completed a modern penthouse apartment overlooking the green hills and blue waters of Rio De Janeiro, Brazil. The Urca Penthouse is located in the neighborhood of the same name, nestled between the Sugar Loaf mountain above and Guanabara Bay below. The views from this penthouse take in the dynamic nature of the bay and the city lights of Rio in the distance. The structure itself is progressive and minimal, with white walls and ceilings, sliding glass doors and neutral furnishings with wooden trim accents. The visual character of the architecture comes from the environment around it, the peaks of Sugar Loaf and the palm frond flora and the glimmering waters of the bay. The result is a refined work of architecture that is comfortable and inviting while presenting an equal focus on the space within and the city of Rio beyond.
