1- The Vestibule
I love this room because it features 'The Murder of Caesar' by Karl van Piloty, which TheJim07 created at my request (thank you again Jim!)

2- The Master Bedroom
The Crawley's love affair with France dates from the early 20th century. Many features of their house mirror or copy architectural details found in buildings and monuments seen during their numerous visits in Europe. Here the theme is the French royal lilies. The whole room is made of stone with lilies carved in the walls and the flooring.

3- The Office Library
By contrast I wanted this room to be warm. In fact more often than not the master of the house spends as many nights sleeping there than in his actual bedroom.
