Horton Plaza seeks to take advantage of its downtown location and adjacency to the famous Gaslamp District by re-imagining the campus as a mixed-use office and retail development that will cater to technology and creative companies. The new Campus at Horton is envisioned with one million square feet of office space for the technology industries, retaining 300,000 square feet of retail and entertainment space. Designs take into account ideologies on the modern workspace, which includes a large number of amenities, flexible spaces for both private and group spaces, large floor plates, and converting all former retail spaces into landscaped, public walkways both for tenants and the general public.

The removal of the many bridges that crisscrossed the retail concourse created excellent visibility into and through the project which will enhance the retailers’ ability to draw street-level activity through the center. A new beer garden and food hall will enrich and reinvigorate the public park that was created from a former mall anchor location. Food festivals, music and performing arts are all integrated into the programming of the park space. Sited adjacent to the Gaslamp Quarter, San Diego’s most popular entertainment district, the new Campus at Horton is an anchor for the food & beverage offerings in the Gaslamp as well as a draw for conventioneers and the millions of seasonal visitors to San Diego’s famous waterfront.

Sustainability has been an important goal for the campus. With a previous life as an iconic mall, we are reusing as much of the existing structure and materials as possible. This effort of reused materials led to a 60% reduction in embodied carbon footprint. Yes, we even ground up existing walkways and then poured new ones using the same aggregate. Additional efforts include largest adaptive reuse in San Diego, Carbon neutrality, Pioneering water stewardship, Net zero energy offices, Future proof, LEED Platinum* live, work, play campus, Well Platinum, Wired score Platinum, and 3-star Fitwell. Awards: Gold Nugget Award of Merit for Best Reimagined Retail Space & a Silver Award in the Evolving Innovation & Aspiration category at the ICSC Global Design and Development Awards.

The adaptation of Campus at Horton redefines this once-heralded urban mall with 1,000,000 sf of tech-focused office space, retaining 300,000 sf for retail and entertainment. The new design considers ideologies of the modern workspace, which include generous amenities, flexible spaces, large floor plates, and ample landscaped, public walkways that connect the site to the city around it, repairing the urban fabric. The planning calls for ample, convenient on-site parking, covered spaces, and valet services for tenants and guests. Vertical construction suits tech and life-science firms, and accordingly the Nordstrom Building is expanding by five stories, adding new views of the City of San Diego and out to the horizon. Additional features include a food hall, roof garden, and an event stage. The design emphasizes environmental sustainability by reusing existing materials, reducing the project's carbon footprint by 60%, and incorporating an innovative black water reuse system. This adaptation marks San Diego's largest reuse project, aiming for carbon neutrality and water stewardship. The campus targets net-zero energy, future-proofing its infrastructure. Designed for LEED Platinum certification, this new place prioritizes wellness and connectivity aiming for high scores in Wired and Fitwell ratings.

“Instead of knocking down buildings and starting from dirt, they kept Horton Plaza, original footprint, it was really about taking a product that had been on the market for a very long time and really transforming it without tearing it down and leveling it, incorporating timeless architecture.”
