What's the difference between ァパート and マンション?

The following is what I translated on Wikipedia:

The so-called "ァパート" is to divide the interior of the building into several rooms, and each room is rented to the renter as an independent residence, which is a kind of collective residence.

ァパート, the transliteration of English apartment, is Japanese English with "ment" omitted.

Judging from the number of floors, due to the limitation of wood structure and light steel structure, most of them are two-story ground-floor buildings.

The first drawing is a typical Japanese two-story building.

マンション is also a British "Masion" made in Japan, which is a bigger assembled house than ァパート. The farthest book means "MAN" in English.
