With its slightly dishevelled bed, black dial-up telephone and unfinished cups of coffee, Room 306 has been left untouched since the evening when King, 39, was fatally shot at the height of the civil rights movement.
"Nobody's ever stayed in the room (since King's death). It's been a shrine ever since," Dyson said.
Visitors who until now could peer into Room 306 via a sealed glass window along the interior hallway will, during the renovations, "get a chance to peek... from the outside,'' Dyson added.
Ray, a white drifter with a criminal record, was convicted of shooting King with a rifle from a building across the street from the Lorraine. Sentenced to 99 years in prison, he died in April 1998 at the age of 70.
In October 2011 King became the first African American to be honoured with a monument along the National Mall in Washington, engraved with words from his stirring 1963 "I Have a Dream" speech for racial equality.
