In the earliest phase (early 1st century BC), the property consisted of two separate houses, each with a central atrium opening to the western cardo and a simple rear garden (hortus). The layout at this stage is compact and symmetrical, following the typical Italic atrium-house model. In the second phase, one house (R2A) expanded dramatically by consuming both original gardens, extending eastward beyond the city wall, and adding a spacious 400 m² peristyle garden surrounded by porticoes. The rooms along this garden show a shift toward openness, natural light, and elite display culture.

The later phases reveal further architectural refinement. The former hortus of the second house (R2B) was converted into another peristyle garden (35a) with porticoes on three sides and a curved wall with window openings toward the garden, an unusual and elegant feature visible in Tang’s reconstruction. The addition of a bath suite on the west and a monumental eastern hall (room 46) in the final phase demonstrates increasing wealth and a move toward villa-like comfort. The plans show extended porticoes forming wind protection, and the small painted altar with a serpent and cock suggests domestic cult activity tied to the garden spaces.

From visual study of the plans, images, and garden reconstructions, House R2 can be understood as a residence that gradually evolved into a highly designed architectural environment where gardens, porticoes, and interior suites were integrated into a unified elite lifestyle.
