Room
noun
If you have a part of a roof, that part is your room. Just imagine a roof divided into sections in a house, with the sections going all the way down to the ground. Each section is its own room, right?
The reading of 部屋 is a bit unusual. Both 部 and 屋 use kun'yomi readings, but 部 is read as へ, due to something called ateji. Ateji is when kanji are used just for their sound, regardless of meaning; or just for their meaning, regardless of sound. In this case it's the former, as 部 was chosen for its archaic べ reading, which was close enough to へ. If this is all a bit much, here's a mnemonic to help you remember this reading:
Imagine you’re renting out a room, but all you hear at night is a constant "heh (へ)… heh... heh... hehehe". An incessant snickering, coming from somewhere inside your room. Hehehe.
