Does anyone know a unique small party venue in Memphis? Maybe a haunted locale, barn or abandoned building?

Question:
My fiancee and I are planning a small party for our reception. We are planning to have a friend DJ it and we will be catering it ourselves with beer & takeout pizza. So we would need a location that will allow us to serve our own alcohol and food. We’ve thought of having it at Ashlar Hall (the old Castle), but can’t find contact information for the current owners. So we’re looking for something unique, maybe even an empty office in an office tower. The Sterick building would be amazing, but it’s been abandoned too long to probably be considered structurally safe by the owners. Any ideas or do you have a place?
Please note that this is not a traditional wedding reception. We don’t want professional wedding venues. Six slabs of concrete and some air conditioning would do nicely.
