MACCO is conceived as an urban landmark for the city, connecting the city´s activities and giving a wide range of cultural expressionism. From this concept the project aims to generate integration between the citizens and the building, through a sequence of open and semi-open spaces, articulated between each other by a concentrical circulation, this is shown as a free plan that links to a pedestrian ramp, which directs the visitor to the exhibition halls, library and cafeteria. This circulation experience provides a visual connection with the Napo River, the main actor of the city and its surroundings. On the ground floor, the jungle theme is the main topic, it is shown through a combination of water and vegetation, elements that surround the central meeting space: a glass box, shaped like an organic cell. The public and cultural spaces, created around the central volume, are the city´s welcoming hall. In the center of the architectural composition, is located the museum, a prismatic volume that contains all the archaeological pieces. Based on a spatial tension concept this main volume is surrounded by three different blocks, with its own complementary functions and lower height, highlighting the museum. The climate condition was a permanent concern of the design, the building becomes a breeze generator that meanders through the volumes, mitigating the intense tropical heat and refreshing the open circulation spaces. The whole building maintains an ongoing dialog with its immediate surroundings, consisting of the river boardwalk, the city, and Napo River.
