It was once connected by a corridor to the Casa Pia and College of the Orphans of Saint Joachim, an architectural complex that consists of a chapel, school, and orphanage.

[1][2][3] The date of construction of the Casa Nobre de Jequitaia is unknown, but is characteristic of residential architecture of Salvador in the mid-18th century.

The house once stood at the base of a small hill range close to the waterfront of the Bay of All Saints; due to successive landfill projects it sits farther inland.

The house is located nearly adjacent to Casa Pia and College of the Orphans of Saint Joachim, also a protected historic architectural complex.

A small sotão, an attic usually reserved for bedrooms of the daughters of the owner of the house, is elongated and placed perpendicular to the main axis of the roof.
