AO, a leading full-service architecture and landscape design firm, has completed Element Mission Valley, a 150-key hotel developed for Driftwood Capital. The project marks the first Element by Westin Marriott property in San Diego County, introducing a brand centered on wellness and comfort. It also builds on AO’s extensive hospitality experience across California, with portfolios spanning leading brands such as Marriott and Hilton.
“The central design challenge at Element Mission Valley was defining a unique identity and arrival experience for the new hotel while ensuring it felt connected to the existing property. Through close collaboration with our partners, we created a design that not only integrates effortlessly, but also reflects the authentic character of San Diego and aligns with a global brand,” said Bruce Greenfield, partner at AO. “We’re excited to see that vision come to life in a way that enhances both the guest experience and the overall destination.”
The seven-story, 98,000-square-foot hotel is located minutes from Downtown San Diego and Mission Bay, with convenient access to Interstate 8. AO’s design is anchored by a choreographed arrival sequence, including a palm-lined drive, a dedicated drop-off zone, and a welcoming lobby plaza. The firm also incorporated expansive glazing, layered landscaping, and a raised exterior patio serving the lobby bar create a social environment. A six-story sculptural wood gateway frames the entry façade as well to establish a strong sense of place.
A palette of neutral tones and wood textures draw from the surrounding coastal landscape, fostering a calm, residential atmosphere for guests. The project’s wood framing and use of natural materials helped it comply with California’s Title 24 energy standards.
Element Mission Valley is designed to offer a residential-style experience, allowing guests to feel at home while traveling. The property features a range of accommodations—including guest rooms, studios, one-bedroom suites, and conference suites—suited for both short- and extended-stay visitors.
Amenity spaces are thoughtfully designed to support wellness and flexibility. Its fitness center incorporates industrial tones, promoting focus and energy, while a 5,300-square-foot conference and ballroom space supports workforce development and special events. Strategically positioned near the arrival zone, the ballroom opens directly to a shared outdoor breakout area.
This plaza connects to the existing Marriott Mission Valley ballroom, creating a flexible communal patio that extends event space while buffering the two properties. The development also provides a seamless pedestrian connection between the hotels, allowing guests to access shared amenities, including the pool deck and on-site dining.
Partners on the project include general contractor, R.D. Olson Construction; structural engineer, Ficcadenti Waggoner and Castle; civil engineer, Kimley-Horn; MEP Engineer, RTM Engineering; and interior design by Linda Snyder Associates.
Other notable hospitality projects within AO’s portfolio include The Inn at the Mission in San Juan Capistrano, Le Meridien Pasadena, and DSRT Surf in Palm Desert. R.D. Olson Construction also recently completed several projects across California including Appellation Healdsburg and AC Hotel Pasadena. The hotel is located at 8757 Rio San Diego Drive, San Diego, California
