Hello! Could somebody please help me translate the following two sentences into English?

台所は食べ物を調理する場所であるから、茶の間に續いて勝手口に通ずる部屋がよい。一家保健の源であるから、衛生を第一とし、作業に便利なように設備しなければならない。

This is what I have so far: Since the kitchen is where food preparation takes place, in the living room...something about the service door. I understand certain words in the second sentence, but it is confusing.
