I don't think that is specific enough, but maybe it is. Here is an extraction from BDAG with full credits.

The word has a few different applications depending on not only context but the grammatical construction of the sentence.
As you can see it can refer to a house in astrological terms, the dwelling place of angels and or as well as the house/dwelling of God, or as the glorified resurrection body.
In my opinion we can't infer one meaning only.
Sure. Remember though this word is only used twice in the Bible and the usage, including the grammar, can be considered consistent with "spiritual body". It will be difficult to definitively claim consistency though, from the Bible, with only 2 usages. I notice the BDAG draws on several sources including Maccabees. I like those books.
Do you accept any credibility in the Book of Enoch ?
