Which branch of interior design focuses on public spaces like offices and hospitals?

The branch of interior design that focuses on public spaces such as offices and hospitals is Commercial/Contract Interior Design. This specialty encompasses the design of various types of non-residential spaces intended for public or business use. Commercial interior designers work on environments that require function, accessibility, durability, and aesthetic appeal to meet the needs of both users and organizations.

Unlike residential interior design, which centers around individual homes and personal spaces, Commercial/Contract Interior Design is concerned with larger scale venues where many people occupy the space simultaneously. The design decisions made in these environments can significantly influence user experience, productivity, and overall atmosphere, which is crucial in settings like offices and healthcare facilities.

Retail Interior Design focuses specifically on shopping environments and retail spaces, while Hospitality Design pertains to hotels, restaurants, and other establishments that cater to guests. Neither of these areas encompasses the broader range of public service and commercial environments like offices and hospitals, making Commercial/Contract Interior Design the correct answer for this question.
