Condominio Unión Norte reflects the modern evolution and vertical growth that transformed the historic Miramar sector in the mid-20th century. Following the passage of the Puerto Rico Condominium Law (1958), Miramar began a major transition from traditional Creole mansions to exclusive high-density residential towers. Built between 1964 and 1967, this 11-story tower stands out for its solid reinforced concrete structure, a classic of modern San Juan residential architecture designed to give ventilation and durability. Its name pays tribute to Calle Unión, a historic street that ends near the legendary Union Club and architectural landmarks such as the Capilla de Nuestra Señora de Lourdes.
The Miramar area stands out for its unique combination of residential tranquility, vibrant architecture, and pedestrian access to the best of San Juan, featuring top-tier gastronomy just steps away from bistros, specialty coffee shops, artisan pizzerias, and renowned restaurants along Ponce de León Ave. and Calle Cuevillas. The condominium is a few minutes’ walk from MADMi (Miramar Museum of Art and Design), local galleries, and community cultural events. It is also close to District T-Mobile, the Puerto Rico Convention Center, art house cinemas, and the Condado Lagoon for activities like kayaking and paddleboarding. Ultra-walkable environment surrounded by supermarkets, pharmacies, banks, and transit hubs, with quick access to Old San Juan, Condado, and Hato Rey.
