Looking for large room (ideally converted warehous

Looking for a large room - ideally very spacious - for me, my partner and our cat. We are a very social couple as we like to meet new people but we also appreciate private time as well. I work from home so I’ll mostly be in my room, and would like to socialise in the living room when I am off. My partner is a head barista, a photographer and Director of Photography while I am an actress. He works in central London. We have a lovely cat called Luna and we want a warm household able to welcome her as well, although she will mostly like to be sleeping on my bed.
