Etherton Interior Design operates from a studio on El Cajon Blvd in College Area, San Diego at 6161 El Cajon Blvd B420, 92115, the international dining and small-business corridor that runs east from SDSU through the heart of the neighborhood. Principal designer Kim Etherton holds ASID membership through the American Society of Interior Designers, a credential that requires documented education, supervised work experience, and passage of the NCIDQ examination covering building codes, construction standards, and design application. The practice focuses on custom residential interiors that translate a client's living patterns and personal aesthetic into functional room layouts, material palettes, and furnishing plans. Window and door upgrades specified during residential interior projects coordinate with specialty suppliers, and Newman Windows and Doors - San Diego in Grantville handles measurement, fabrication, and installation for replacement window and sliding-door systems. The El Cajon Blvd address places the studio in the College Area commercial district between SDSU and the Rolando neighborhood boundary, within the 92115 ZIP that also covers the campus-adjacent residential blocks south of Montezuma Road. Interior design services cover space planning, color consultation, furniture sourcing, custom upholstery specification, kitchen and bath material selection, lighting layouts, and art curation for residential clients across San Diego's eastern neighborhoods. Projects in the mid-century housing stock common to College Area, Allied Gardens, and Del Cerro involve matching period-appropriate design elements with contemporary livability upgrades, balancing original architectural character against modern open-plan preferences. Exterior hardscape and planting design that complements interior material choices routes through landscaping providers in the area, and Armstrong Garden Centers in Grantville supplies container plantings, hardgoods, and landscape materials for indoor-outdoor design integration. The Saturday studio schedule accommodates working clients who need weekend design consultations without midweek time off.
