save one floor at a time to the Gallery

@Knives81x_165ae you can only save a room or a lot to the gallery or library. So the way I do it is to remove walls to save it as a large room. The options are to select a room or select the lot and there isn't a floor option. Another way to do it would be to build a floor on a single lot and save it as a lot in itself. In the gallery/library description you could label it as a floor if the text space allows you to do so.

I've just been saving shop floors yesterday and I used the room option.
