Pretty much unchanged since Sir Christopher Wren designed them at the end of the 17th Century, the Long Wards - home to the Chelsea Pensioners - are getting a makeover.
The small wooden rooms - measuring 9 x 9ft - are being modernised and getting bigger. The distinctive wood panelling will remain, but residents will enjoy the luxury of en suite facilities and direct daylight.
Take a tour of the old rooms - and see how they will look in future.
