William and Kate's living room is furnished with a plain cream sofa and a dresser positioned against one wall (seen directly behind Kate), where the couple have a combination of framed family photographs, two blue vases and a larger brown flowerpot.
The first framed picture shows Kate and Prince Louis at Kate's Back to Nature Garden in 2019, while another is of Prince George and Princess Charlotte on their first day of school in September 2019.
A third photograph features Prince William during his solo trip to Africa in 2018, and an additional snap is of Prince George wearing a white England shirt, which Kate took herself and released on his birthday in July 2019.
Soft sand-hued walls add to the neutral aesthetic of the room, where the Duke and Duchess have also mounted two paintings in rectangular bronze frames.
