I live on a corner lot, but even so I have close neighbors. I never open the south facing utility room window due to the closeness of the neighbors house. I hated this as great sunshine comes in through the window and I love sunshine. So, I fixed that with some privacy window film purchased at Home Depot.
Going up. See how close she is?!?
After! Sunlight still streams in, but the neighbor can't see if I'm doing laundry in my very last pair of clean undies! Not that this has ever happened, not that it hasn't!
