The two men had previously designed the first modern luxury resort in San Juan, the Caribe Hilton.

Another part of the complex, the seashell-inspired building for the restaurant La Perla, was designed by architect Mario Salvadori.

[4] The hotel's design incorporated tropical climate features such as cross-ventilation, natural illumination, open lobbies and seamless transitions between inside and outside spaces, with details supposedly relevant to Island traditions: an interior patio, blinds, a mirador encompassing both the sea and the city and the use of water throughout as a leitmotif.

[5] In 1976,[6] management of the complex was taken over by Hilton International[7] and the resort was renamed the Condado Beach La Concha Convention Center, with a huge convention wing built between the two existing hotel structures to physically connect them.

The hotel's Casino del Mar is located on the street level of the new tower.
