The building is a typical house above the arcades of Bolzano, that extends from the southern arcades to the via argentieri. Originally it was a commercial building on the side of the arcades with a warehouse connected to the south and an initially independent residential building on via Argentieri. The existing building grew from those three individual houses to the present building stock with three atriums.
The Romanesque core buildings from the 13th century were expanded in the following centuries. The house on via Argentieri was already supplemented to its current width in the late Middle Ages. While in both buildings the first Gothic extensions can no longer be seen or only on older openings on the facades, the following extensions of the Gothic and Renaissance still characterize the external appearance and the impression of the interior. In the house on via Argentieri, the rooms on the ground-floor were vaulted around 1500 and in the floors above, typical residential units with a parlour, kitchen and chamber were created. The northern house on the arcades is only subsequently extended representatively and equipped with characteristic room elements of a Bolzano townhouse with forecourt and kitchen to the atrium.
Between the 17th and 19th centuries, only furnishings in the living rooms were renewed and supplemented; it was not until the 20th century that there were again formative structural interventions.
In the second half of the 20th century, the attic floors were adapted, one of which was planned by the South Tyrolean architect Othmar Barth, for residential purposes and the rooms of the upper floors were increasingly used for the extensive art collection.
The historic house above the arcades, with its structure and equipment, is an impressive example of a Bolzano civic and trading house. The building has been demonstrably in operation as a commercial building since its construction and has largely preserved its medieval and Gothic foundations. Under the ownership of the Eccel, a family of merchants, an era begins as a furniture store and art gallery, which gives the house its current name and purpose.
