The given maps depict information about the changes to a communal area for students after 5 years.
From a quick glance, it is clear that the room has undergone many changes, including replacements, additions, and removals. And the purpose of these changes is to develop facilities for students.
In the last 5 years, the room was designed with four round tables, which could accommodate a maximum of 24 seats for pupils. At the top of the map, there was a row of cooking-related facilities, including a cupboard, sink, bench, microwave, and a fridge. Finally, there was a bookshelf at the right corner of the room for students.
But now, the common room has been developed with many new material facilities. First, the two round tables have been replaced by rectangular ones, which can save space for other new things, such as a bench for laptops at the bottom of the map and a drink machine next to the refrigerator. In terms of replacements, the bookshelf located at the right corner has been superseded by a television with three armchairs in front of it, and the right-side bench has been replaced by another microwave.
