If a commercial architect is working on a specialized facility, the design process changes even further. For example, medical or health care facilities need to have plans to keep the area sterile and protect patients. Hospitality buildings, like hotels, need to ensure that they have space to meet their guests’ needs as well as provide entertainment and restaurant options. Retail buildings must have space to display their products for sale, give customers a place to park and provide easy-to-find restrooms.
