The given diagrams depict an office room at two distinct times, before and after advancement. Overall, most features have changed, except for the storeroom. In addition, the period of upgradation witnesses the deconstruction of the kitchen, canteen, and grass area, the presence of more workplaces and public areas, and the relocation of the restroom.
Regarding the features being diminished, the kitchen and canteen were located at the top of the layout first, after which they have been demolished to make room for more officerial spots. Similarly, the places of grass, which were a relatively large area in the first layout, have been pulled down for other facilities.
Moving to the remaining features, the office rooms have been redistributed from 4 rooms into 2 larger ones at the bottom of the layout. Moreover, the new two areas of seating and gathering are notable, which have been added in the space of the old removed grass area. Additionally, there are chairs included for the meeting attendees. To adapt to the new office layout, the entrance at the northeast has shifted to the centre, and the other one has experienced no change. Finally, the storeroom at the upright corner of the room has stayed stagnant throughout the development; however, there is a new coffee machine next to it.
In summary, the changes in the office are clearly observed in the construction, demolishment, and relocation of certain features.
