247th day of 2016.
After doing the first round, second round is much easier to play with. The basic layout is the same, but the big difference is I tried to separate the 3 ends of the building. The most notable feature is the big void above the Great Hall which would effectively separate the Royal's family space and official & guest zone.
I still have a basement and cellar for all the kitchens and main services, right below Great Hall. Also, after I get a hold on the scale, I would like to have complete separation on 2nd floor from the back and front ends.
