King Charles III and Queen Camilla will later unveil their bronze portraits at the King’s Boundbury development in Dorset.
It will be the royal couple’s first visit to society since their coronation.
The monarch will also unveil a bust of her father, the late Duke of Edinburgh, in a garden on Boundbury’s Pavilion Green.
The visit marks the completion of Queen Mother Square, the center of the development. The entire community is scheduled for completion in 2028.
Bronze figures by sculptor Ian Rank-Bradley sit above a plaque naming those who helped build the square.
The bust of Prince Philip is a new version of the work created in 2000 by sculptor Francis Segalman.
It is located in The Duke of Edinburgh Gardens and will be officially opened by the royal couple.
Construction began in Boundbury, on the edge of Dorchester, in 1993 based on architectural principles championed by the future monarch.
By 2028, the Duchy of Cornwall community will grow to 2,740 homes from the current 2,300, according to Buckingham Palace.
The King, Prince of Wales, last visited Boundbury in May 2022 to open the new Great Field play area.
