Pretty sure I've written about this before, but I kind of hate writing scenery. I can either see the location in my head and don't want to waste time thinking up how to describe it, or I don't care about the location because it doesn't impact the scene at hand (especially in dialogue-heavy scenes). So I can't say I was surprised when a big part of the feedback I received in my class last semester was that people didn't know what time period they were in (it's a period piece) or what places looked like. They wanted more grounding in the scene. At the time I wanted to throw up at the thought of taking time away from the plot to describe things, but my professor gave me what has come to be an invaluable piece of advice:
Diagram the scene.
As in, draw it out. Where are the chairs, what does the carpet look like, how many levels does the house/building/spaceship have, what kind of doors are there, does it have a kitchen, are there windows, etc. Don't just think about it, draw it out. This might seem like overkill for some stories, but it was essential for mine, and a handy tip for anyone telling a story that exists in a physical location (yeah, I'm talking to you).
In diagramming you'll find yourself asking questions you never thought of before - now that I know where everything lives, what about decorations? Colors? Does it make sense to put a chair right in the middle of this room? Is the bed too large for the room? Could the character really open the window from there? It's also a lot easier to describe a room when you're looking at a physical picture of it, not just trying to hold images in your head. You'll have a blueprint that you can hold yourself accountable for in all the scenes in your book, and you won't have to bother trying to remember where you put that pesky bookshelf.
You don't need to diagram all the locations, just the most essential ones. Think about it like an episode of Saved By The Bell - how many places do they really go? There's the school hallway lined with lockers, usually a classroom or two that look mysterious alike, and The Max. If you've watched the show, you can clearly see these locations in your mind when thinking of pivotal scenes of the show. You want your readers to have the same instant recall about your own scenes. If you don't ground your readers in the scene they'll feel lost about where they are and what they're watching.
Have you ever diagrammed a location in your story before? Did it help?
