The mural, which has become a shrine for fans, is on the side of Morleys department store, just opposite the Tube station for Brixton, the south London area where Bowie was born in 1947, said The Hollywood Reporter.
Thousands of people visited the artwork, after the demise of the music legend on January 10 following a secret battle with cancer.
Lambeth Council has said its considering renaming the spot where the mural sits and suggestions for a permanent memorial, including a statue of the singer, are up for discussion.
"We are also in contact with the Bowie fan club and other Brixton organizations who want to honor the memory and legacy of this extraordinary artist. We will share any word we get from his family that will determine what we do next," said Councillor Lib Peck, leader of Lambeth Council in a statement.
