As part of my assignment I need to describe details of Thomas Kinkade's artwork [Silent Night](http://www.thomaskinkade.com/magi/servlet/com.asucon.ebiz.catalog.web.tk.CatalogServlet?catalogAction=Product&productId=325&menuNdx=0).
I can't find how is the left part of the cabin called (part where you can see Christmas Tree).

I have several options: 

* patio
* balcony
* deck
* verandah
* porch
* loggia (as for me, it seems like most appropriate)

but I'm not sure that at least one of them has suitable meaning.

What is appropriate word for this?
