In The Castles of Burgundy, when placing building tiles, can the same type of building be constructed repeatedly on tiles within the same area?

In The Castles of Burgundy, each player's estate is divided into multiple areas of different colors (such as the yellow monastery area and the brown building area): If my estate has a single connected large building area containing 4 brown hexes, can I place two identical buildings in this area (for example, two identical warehouses, each triggering its effect once when placed)?
