Along the Canal the number of "fondaco" houses increased, buildings combining the warehouse and the merchant's residence.
A portico (the curia) covers the bank and facilitates the ships' unloading. From the portico a corridor flanked by storerooms reaches a posterior courtyard. Similarly, on the first floor a loggia as large as the portico illuminates the hall into which open the merchant's rooms. The façade is thereby divided into an airy central part and two more solid sides. A low mezzanine with offices divides the two floors.
The fondaco house often had two lateral defensive towers (torreselle), as in the Fondaco dei Turchi (13th century, heavily restored in the 19th). With the German warehouse, the Fondaco dei Tedeschi (which is also situated on the Grand Canal), it reflects the high number of foreign merchants working in Venice, where the republic supplied them with storerooms and lodging and simultaneously controlled their trading activity.
