Park noted that the iconic buildings in downtown skylines typically are commercial properties, but Bosa Development's goal is to create residential towers that are more architecturally compelling. Regarding Bosa's latest building, Pacific Gate, Park said, “The design is going to be clean, with a singular gesture.”

The exhibit features three iterations of KPF's initial renderings for the 41-story Pacific Gate, which start off boxier in its configurations to the current rendering which is comprised of two nested curved glass towers that will rise as a single column from a three-story ground floor podium on the south side of the tower planned for retail space. As Bosa's director of sales and marketing Bemi Juahal told GlobeSt.com exclusively in August, “The project will feature ocean, bay and city views and will be amongst the tallest buildings Downtown. The residences will offer first-class service and exceptional amenities. The oval glass residential tower is designed by architects Kohn Pedersen Fox, in collaboration with Vancouver-based Chris Dikeakos Architects, who created a landmark design that will evolve the San Diego skyline.”

According to KPF's president James Von Klemperer, the holistic design approach focused on the interaction, functionality and visual aesthetics between the building's exterior and interior and the sites and features of the city. This will allow a resident or visitor to experience Downtown's buildings as a collective, creating a more cohesive and memorable journey.”

Also at the event, Bosa lauded the Manchester Pacific Gateway project as another sign that there is demand in Downtown San Diego for more upscale, urban offerings. The project is a 2.9-million-square-foot mixed-use project that will include hotels, commercial office space, a Naval administrative office building, and leasable retail space and cultural attractions overlooking the San Diego Bay.

Rethink Downtown: Behind San Diego's Skyline, available to residents and visitors to San Diego at no charge, is open daily from 11 a.m. to 5 p.m. and is located at 700 First Ave. Open for a limited run, the 3,000 square foot Rethink is an exhibition-lecture series that celebrates San Diego and asks visitors to ponder Downtown's future, where it's going, and how architecture, design, amenities and quality of life enable San Diego to matter on a national scale, from Millennials to Boomers.

In addition, Bosa is hoping to use the exhibit to spark an Instagram phenomenon regarding Downtown San Diego. Photographer David Flores, who has captured the essence of Downtown San Diego in a photo essay for the exhibit, says, “We hope this challenge will inspire our current and new Instagram followers to explore their city and learn about other communities around the world. This gives city dwellers a chance to visit a neighborhood, landmark, or business they've never been to and to start a conversation with other urbanites from far-away places.”

To enter the challenge on Instagram, contestants are asked to:

1. Repost the challenge and tag at least one friend the participant wants to join in the conversation.

Each week's winner will be announced each Friday through October 30, 2015, along with the theme for the next week. One grand prize winner will be chosen at the closing of the contest on Friday, Nov. 6.
