Carpenter is a tricky term because wood is used in so many ways. This is strictly UK biased: In building terms we distinguish a first and second fix carpenter. First fix is mostly structural and second fix is the rest. If your hair is wet its probably first fix - roof trusses and the like. Second fix will include things like skirting boards. It's not a hard and fast rule and will probably involve the same people. These trades are known as "chippies" (sing. chippy). We also have cabinetry (your furniture smith - nice one) and other wood working trades. They are all called carpenters. A chippy is a carpenter and I think this a rare case where the nickname is more common than the real name. Civilians will often call a chippy a "builder". A cabinet maker is never known as a builder or a chippy. The chippy thing is because a very small piece of wood is a "chip". I think I know why you are a bit confused about the word carpenter. In the US and elsewhere, houses are mostly wooden. When a house is nearly all wood, then the word carpenter should mean builder. In the UK and elsewhere houses are built of sticks and bricks, mostly bricks.
