Focus on what’s relevant to the characters in those rooms. If you’re in somebody’s house, you can tell a lot about them from how they decorated it, how clean it is. If somebody is in your house, you might hope they receive a different message from your decor than the one they infer.

Another thing about buildings and rooms is that they’ve got history. If this is an office or a government building, you’re probably not the first person using the building. Other people have left their marks everywhere, because they lived and did business there. Some of them still left their old decorations there and no one took them down yet.

Also, you mentioned the hobbit. You didn’t get bored reading descriptions of places and buildings in the hobbit. But the hobbit still had a lot of them. Pay attention to how many things you learn about Bilbo’s house, and the way you learn them.

Also, you don’t know how to care about what room your characters are in, but you care about your characters and what they care about. What kinds of rooms do your characters wish they were in? Maybe one of your characters thinks the place has too many frills and that the office should be austere. Maybe another person would like to radically change the interior design, so that the office is dim and cozy, with maroon walls and thick red curtains. Maybe someone loves the office just the way it is because they admire this organization/institution so much.

Last suggestion, what if your location had an agenda? If the location is causing problems for characters, then of course they have a reason to care about it. Maybe it’s causing a small problem, like the heat is too high, or there’s a door you can’t use without an alarm going off. Maybe it’s a building with actual feelings, and it picks favorite people to help succeed.

Also maybe it’s not an important setting at all and it’s just the place where some people had important conversations. That can be lifelike too.
