Many of the most significant buildings in the world are mixed-use buildings, towering hundreds of meters in height with an impressive number of floors and housing administrative/office spaces, commercial spaces, hospitality and residential spaces. Office buildings are one of these and are usually iconic structures that stand out wherever they are built. According to Whole Building Design Guide, “an office space refers to a variety of spaces including meeting spaces integrated into the office environment, reception, office support spaces such as work rooms, storage rooms, file rooms, mail rooms, copier areas, service units/coffee bar, and coat storage integrated into the office environment, and telephone and communications equipment rooms located in tenant suites containing tenant equipment”.
