How would one describe the house in "The Listeners" and the situation around it?
I'll start with the basic situation. A man on a horse has arrived at a lone house because he promised that he would. Readers don't know why he promised anything. It is night when he arrives at the house, and he knocks on the door several times. There is no answer at all. It's possible that everybody is asleep. It's possible that nobody is home. It's possible that everybody in the house is dead, and their ghosts are watching the man knock. Regardless, since nobody welcomes the visitor, he leaves.
The house itself isn't described in detail, but some key features are mentioned in the poem. Readers are told that the house is a "lone house." That tells me that the house is not in some kind of city, town, or neighborhood. Line four also tells readers that the house is in or near some kind of forest.
I believe that the house is a two-story house. I think that for two reasons. First, the man is able to see stairs that empty into a hall.
Stood thronging the faint moonbeams on the dark stair,That goes down to the empty hall.
No head from the leaf-fringed sillLeaned over and looked into his grey eyes.
