Hello. North of the house was a barn. A barn was north of the house. There was a barn north of the house. I would like to know the grammar behind the first sentence: name of the structure (some kind of subject inversion?) and use; is it mainly used for literary effect? By the way, I don't think we need any prepositions, but if we wanted to add one, would 'to (the) north ...' be okay? Thank you very much.
