a luxury venue

I’m getting married next year and right now I don’t intend on having an after party tbh just a small church wedding and going on my honeymoon but I’m debating having a party if I could find a nice hall. Like a ballroom somewhere near Kent/Dartford? I personally prefer something that looks luxurious similar too the picture attached. Any recommendations? If I could find a nice venue I’d have the party😂🙈. The one pictured isn’t available on my date any recommendations? Preferably a large ballroom too.
