The house has been described as the only untouched Lutyens interior in existence. Lutyens suggested the colour schemes for each room and in a letter to Princess Marie Louise he insisted that carpets should not be made until the colours were selected and ceilings were complete. He also designed many of the furnishings himself. Some of these, such as the Napoleon chair, are still produced today.

Lutyens's sense of humour is also wonderfully demonstrated in this drawing, which shows a maid in the bath!
