The building is surrounded by courts adorned in various ways (exedrae, gardens, etc): the north court which has still to be dug up, was probably a garden, the south court a service area. To the east, the way that connected it to the rest of the villa, crossed a barrel vaulted cryptoportico. Inside, the architectural order is renewed to favour the elasticity of the walls.
The building is brightly light by means of large windows and thanks to the different heights of the roofs. In such a way, the windows of the inner rooms with higher roots were opened above the extradosses of the domes of the external rooms with lower roofs.
The main structures are in bricks, the rest in opus mixtum. With the exception of the hall, which was roofed in wood and tiles, all the other rooms were covered with various types ot vaults (barrel, spherical and semi-sphencal) with round, semi-circular and square oculi.The rooms with fragments of plaster and marble decorations, were instead used for the different thermal practices (massages exercises, etc).
On the west side are the heated rooms, furnished with a service corridor that connects them to the praefurnia (furnaces) positioned at a lower level, which could be reached by means of a stair starting from the south courtyard. The different and rich solutions adopted for the vaultings and the decorations are clearly recognizable. Instead, today it is difficult to distinguish the calidarium from the tepidarium, since all the rooms have the elements for heating.
