In the ?barri del mercat?, in the city of Valencia and very close to its Lonja, there is a building complex which is the object of this study. The research, carried out from the simple field of toponymy, to the constructive analysis, lead us to suppose that it is the building of the Valencian trade union of cloth-shearers. It can be seen how the building now camouflaged by other subsequent interventions, corresponds to a type that cannot be related to those usually built in the city of Valencia. Its origins clearly from the Valencian self-governing period splendor, its dimensions and the finishes used in its construction seem to refer to a medieval workshop. A structure of great importance has been recognized that jointly affects the different properties today. This together with other circumstances of their own as necessary to exercise the office of abaxador, existing in the building, have come to confirm this hypothesis. This article offers unpublished graphic documentation, which gives an account of the current status of the property and suggests a reconstructive hypothesis, both in plan and in volume.
