Studio E Architects is an architectural firm founded in 1987 by Eric Naslund, FAIA. The company offers services ranging from private residences and affordable housing to mixed-use, civic, and urban-planning projects, and the team portfolio has received over 130 awards, including the 2020 Orchid Award for Urban Planning from the San Diego Architectural Foundation, the 2020 National Award of Excellence from the National Association of Housing and Redevelopment Officials, and the 2020 Ruby Award Project of the Year from the San Diego Housing Federation.

The Washington Street apartments, in La Quinta, are a gleaming example of Studio E’s ability to renovate and expand an existing complex, enhancing it to meet current sustainability needs and strengthen social connections within a community. Beyond updating the 72 existing units, with a broad palette of mountain colors, the team also added 68 new units, two community buildings, and swimming pools and enhanced the outdoor areas. This low-income senior housing now radiates a positive, cheerful, and lively atmosphere that promotes healthy lifestyle, and the project secured multiple honors for the Studio E team, including a merit award from AIA San Diego and the title of Best Affordable Senior Housing Community from PCBC’s Gold Nugget Awards.

One World Architecture

9826 Ogram Dr., La Mesa, CA 91941

Rainbow Blossom Natural Foods is a regional leader for the natural- and organic-food movement; that is why they partnered with One World Architecture to design the first LEED-certified retail store in Kentucky. The team reused an existing building’s foundation and utilities, substantially reducing the amount of waste and resources required for construction. In addition, over 50% of the materials were sourced from regional manufacturers, significantly diminishing the impact of long-distance transportation, and onsite processes were adapted for eco-friendly context, including the reuse of heat from the refrigerated food cases within the store’s HVAC system.

One World has been optimizing green design processes for over 15 years. Along with their sustainable designs, they use real-time energy modeling and analysis software from the start of the design process, minimizing the amount of reworking and second-guessing. This process, along with the team’s effort to implement innovative site-specific solutions, ensures that every project they handle is completed embodies the client’s needs and long-term vision for success.
