LeTourneau Architecture

250 Newport Center Drive, Suite 305, Newport Beach, CA 92660

Doubling as a showroom for the Alvista Community in Riverside, the Canyon Creek Leasing Center features bold architectural lines in its modern exterior nestled within Sycamore Wilderness Park. The muted orange and gray tones continue in the interior, which showcases the apartments’ flowing layouts. Multiple sitting areas lie just beyond the galley kitchen, which features a light wood eat-in waterfall-edge island fronting glossy white cabinets and drawers. There’s also a gym on the property which provides great views of the surrounding greenery through window walls.

The space was designed by LeTourneau Architecture, which has been serving Los Angeles, Orange County, and the surrounding areas since 2006. Principal Architect Chris LeTourneau brings 20 years of experience designing across California after earning his bachelor’s degree in Architecture from the California Polytechnic State University-San Luis Obispo (Cal Poly) and his master’s in Architecture and Urban Design from Columbia University. The firm blends innovative and practical design, incorporating renewable materials into its architectonic detailing.

Brandon Architects

151 Kalmus Drive, Suite G-1, Costa Mesa, CA 92626 

President Christopher Brandon’s, AIA, career was influenced by his formative years in a small town in Northeast Oregon, where he learned to value natural beauty at a young age. Several years after earning his Architecture degree from Cal Poly, in 2009, he established boutique full-service architectural firm Brandon Architects and he has since designed custom homes, commercial projects, and hospitality projects. His wife, Kaley, joins him as vice president, handling business management. They work together with their team of AIA, LEED AP, and Building Design + Construction (BD+C)-certified designers serving Newport Beach, coastal Orange County, and beyond.

Located in an existing office building in San Clemente, Brewhaus is a multifunctional brewery space that can serve as a pub, an event venue, or a leased facility for microbreweries in the community. Brandon Architects designed a separate wood-trellised entry to the space where the building meets the hillside past the first-floor offices. The warm wood accents continue in the interior, where visitors get the opportunity to interact with the brewing process while enjoying views of San Clemente Valley through window walls.
