You're right about that one! Though "lab" could also refer to Labrador, a dog breed
Maybe Research Facility/Catility :3
I agree with all that, I am just thinking from a construction standpoint. The people who build will be making houses. They won't become homes until they are inhabited, and each one is only a home to one person or family, the rest are all houses.
But it doesn't really matter, it is just something that came up in class a few days ago. Home / House . One of the many things that is taught incorrectly in schools here. No one in China seems to know the word, 'person'. They always say people. But this comes from directly translating things as there are no plural nouns in Chinese just as there are no verb forms. Qu (Go) is the same whether it's me, you, them, past, present or future.
Grammar in Chinese is very simple, it's just a shame that the reading and writing is a nightmare.
