Prince William and Prince Harry will honor the memory of their mother Princess Diana through a new memorial garden to be built in Kensington Palace in London, the childhood home of the British royals. Next year will mark the 20th anniversary of the tragic death of Diana, who died in a car crash in Paris at the age of 36.

William, 33, and Harry, 31, are backing the plans for the new memorial garden which will commemorate the life of their mother. A spokesman for Kensington Palace confirmed that plans were being explored by palace officials and management at Historic Royal Palaces.

The Historic Royal Palaces is the charity that looks after some of the most iconic sites in the U.K., including the Kensington Palace. It is recruiting a team to start the project, which is still in the beginning stages. The jobs are currently being advertised on their website.

The palace spokesperson added that William and Harry were being kept “informed” of the developments. “No tribute to Princess Diana would be given the go-ahead without the princes’ approval,” he said. The project is expected to be complete ahead of Diana’s 20th death anniversary on August 31, 2017.

Historic Royal Palaces is also looking for a new gardener to help with the project. Meanwhile, there are many other memorials of the princess which include the Diana Memorial Playground at Kensington Palace, the Diana Memorial Fountain in Hyde Park, and the Diana Memorial Walk at St James’s Palace, all in London. The news of the Diana memorial garden comes soon after Harry gave an interview to “Good Morning America” where he spoke about his mother.

Harry said during the interview that he and William were determined to continue Diana’s legacy by drawing attention to worthy causes. “We will do everything we can to make sure that she’s never forgotten and carry on all the special gifts, as such, that she had and that she portrayed while she was alive,” he said. He also hoped that a lot of his mother’s talents were reflected in the work that he did.
