请教RF4

四十还是惑

今天查了CITY的网，这是RF4的定义，This zone provides the opportunity for primarily semi-detached and duplex housing. 哪位高人可用中文给解释一下，这种地的用途。先谢谢了

Semi-detached housing consists of pairs of houses built side by side as units sharing a party wall and usually in such a way that each house's layout is a mirror image of its twin.  this style is sometimes colloquially called a duplex; elsewhere, however, "duplex" refers to a building split into two flats/apartments (one above the other). The style is usually referred to in the mid-Atlantic (particularly Philadelphia) as a twin.
