My girlfriend's 21st birthday is approaching and I would like to fulfill her wish of having fireworks during her 21st. She's currently living in SE1. I understand that the rule of fireworks is that you can only fire off from your private garden. Was hoping that you can advice me on authorities of places like Jubilee gardens that I can seek permission from to put up the magical display. I tried emailing restaurants with private gardens but have yet to receive any positive replies. Are roof gardens feasible? Hope you can help! Thanks a lot!
