Please help me review my description of this map

The plans illustrate the current or present layout of an airport and how the airport will appear following redevelopment next year.

Overall, it is clear that the airport will be enlarged and more specialized rooms will be added to it.

Looking in more detail at the departure and arrival areas, whereas the former currently has a check-in and cafe, in addition to a security area and passport control, the latter is largely empty, with the customs and passport control room being the only room in it. By next year, however, a cafe, ATM, and car hire will have been added, and in order to build the car hire, a small part of the arrival section will be enlarged. The check-in, which is in the far west of the airport, is going to be relocated to the middle of the airport, and a bag drop will be erected in the space left by it. Similarly, the cafe will be moved to the south of the bag drop. The security, passport control, and customs areas will all remain unchanged, although to the north of the security area, shops will be opened up and the single doors will be converted into double ones.

If we look at the top-most part of the current airport layout, we can see two connected walkways that are almost completely surrounded by eight gates. In the future—that is, in a year—not only will this part be made significantly bigger, but also ten more gates will be added, making the total number 18. It is worth noting that a sky train will replace the walkways.
