Thanks, This looks really amazing. but a question, how did you achieve the roofing in the balcony and bbq area?

It's pretty simple, just leave a tile in the borders of the balcony, and use the 3-hip roof to outline it. Then after that, remove the side walls of the roof and add a half wall of your choice, and then to finish it you ajust the roof angle to match better!
I'm almost sure that there's a tutorial in youtube, if you haven't really understood I can find one and link it to you :D
