I’m pretty sure it wasn’t a woosh. It’s really common to build “fake” buildings to hide equipment. The OP says it already existed, but all the windows look like typical hidden building fake windows. There’s a wall behind all of them. You can find these buildings all over, hiding things like electric substations, oil jacks, subway infrastructure, and all kinds of other things.
They built a building in front of it that looks pretty close to a normal house for all the support equipment. Thry probably didn’t need to do that.
Actually I’m pretty sure they did have to do that in order to build it in this neighborhood. Also, they didn’t build this house, it was already there.
