The base itself starts out as simple, seemingly hexagonal or octagonal building composed of bricks, with large, square windows or double doors adorning many of its faces. Topping the lower structure is a series of smaller structures suspended in the air at various heights, which compose the rest of the headquarters. The building, living up to its owners, has an outlandish appearance to it. The area was portrayed differently in the anime, in which, despite retaining the rocky look, it is mostly surrounded by lush foliage. A series of small hills is visible not far from the place.
In the manga, the building itself sits in an extremely rocky area completely lacking any sort of vegetation, consisting of a multitude of large boulders, with a narrow gorge leading to the building itself. The Fiore Branch building's location lies on the south of Crocus.
