On the west side of the plaza are attached Buildings 3, 4, 5, 6 and 7, built in different stages. These foundations support different temples that possibly had a vault.

Building 4: It is the highest of the complex and important sculptural monuments were found here, including four large carved slabs that top the alfardas of the main staircase, as well as domestic evidence that indicates a possible elite residential function.

Building 7: Five fragments of carved stelae were found here inside a rectangular cist covered with slabs.
