Newton told The Associated Press on Tuesday that a yearlong effort to transform his sprawling Casa de Shenandoah estate into a tourist destination is almost complete.
The attraction was initially slated to open in December, but Newton says the project was delayed because construction permits were not approved as quickly as expected.
Revised building plans submitted last month call for expanding the attraction's museum space and a theater where Newton will perform at least occasionally.
Newton received permission last year to turn his lavish home into a tourist venue.
Visitors will be able to survey his European antiques and celebrity mementos, including Nat King Cole's watch and a Johnny Cash guitar.
