That represents a major change in how one of the world's most recognizable royal residences is used.
It also reflects a broader question facing the monarchy:
How can an ancient institution adapt to a modern society without losing its historical identity?

A New Chapter for Buckingham Palace
When the refurbishment is finally complete, visitors may see a Buckingham Palace that functions differently from the palace associated with previous generations.
It will remain a symbol of the Crown.
The famous balcony will remain part of Britain's royal imagery.
The State Rooms will continue to have ceremonial significance.
Official visitors will still enter its doors.
But the daily private life of the King and Queen will remain centered elsewhere.
That distinction may become increasingly important.
Buckingham Palace can remain the public face of the monarchy without necessarily being the King's private home.
