The urban renewal triggered by the first phase of the Antara mixed-use development (2006) was one of the single most significant actions in the north-west of Mexico City. It elicited a new urban order that completely changed the profile of the area, increasing the real estate value, promoting densification and attracting capital investment. Maintaining this same outlook, Antara proceeded to develop the second phase of its master plan, divided into two stages: (1) Antara Corporate Building I and (2) Antara Corporate Building II. These adjacent buildings are located on the north-western side of the complex.
ANTARA CORPORATE BUILDING I establishes a direct architectural dialogue and a close relationship with the first phase of the development. These similarities are apparent in the design and intentions of the spaces, uses, circulations, materials and structures of the two buildings.
The architectural layout of ANTARA CORPORATE BUILDING I takes up parallel and radial lines emerging from the first phase of the Antara development, with the result that their floor plan is rectangular, but with curves on the north and south façades. The design of the façade corresponds to and emphasizes the internal functioning of the building, and presents an interesting combination of differently-sized rectangular modules that all share a single vanishing point and are based on a prefabricated design. The vertical elements continue upwards beyond the final floor and wrap around this last floor, emphasizing the verticality of the building. The rhythm of the different modules forms a play of light and shadow that creates a sensation of greater depth in the building’s faces, an effect that changes over the course of the day.
The program of offices was designed in the simplest possible manner, given its purpose and function. The central nucleus containing the services (washrooms, vertical circulations and ducts) is located in the center of the building, with the aim of boosting the exceptional panoramic views over the city in the rest of the building. In parallel, this design enables open-plan, flexible spaces that can be laid out in a range of internal configurations.
A large plaza was designed for this second phase, facing Miguel Cervantes Saavedra Avenue with fountains and gardens as well as the principal vehicular and pedestrian access points. This level includes a motor lobby with valet or self- service parking for both towers. The ground floor and basement levels are independent, have an irregular form and are linked internally with spiral ramps for their smooth functioning.
Construction of ANTARA CORPORATE BUILDING I was successfully completed in 2013. It was designed as an office building over 13 floors with the lower two floors assigned to retail use. It includes a mezzanine circulation floor, a mechanical floor and seven underground parking levels plus a service level for wastewater treatment and cisterns. The total height is 76.85 meters above street level. The built area for offices is 27,469 m2 while the retail space covers 2,389 m2 together with services and terraces totaling 36,609 m2. The underground parking covers 49,170 m2 of built area, giving a total of 85,779 m2 of built area. The floor area is 2,166 m2 with 3,808 m2 of open areas, for a total surface area of 5,974 m2.
The ground floor of ANTARA CORPORATE BUILDING I includes the arcade the serves as the entrance to the offices and retail stores and connects to the shopping mall and to the first level. The first floor also contains a number of retail stores. The office reception, security and transfer floor is located on the second level. These first three floors are adjacent to the mall, while the south façade of the fourth floor incorporates a cantilevered section that extends over the roof of the food hall´s terrace area of the first phase.
