Modern Interior in a Historic English Mansion

Despite the fact that the family lives in a historic English mansion, they chose a modern interior for their home, which is closer to them in spirit. Through classical arches peek whimsical chandeliers, a stained glass door surrounds wallpaper with flowers, and above the historic fireplace in the living room a neon sign has been placed. Moreover, the designer chose a color palette not typical for English homes with pastel and bright tones, which yet harmonizes with the cream-brown classicism. What do you think of this mix of epochs and meanings?
