Having spent the first few months of her life at 17 Bruton Street, the future Queen Elizabeth II moved into her parents’ new property at 145 Piccadilly.

The property, located close to Hyde Park Corner, was previously the townhouse of the Marquesses of Northampton (interestingly, it was while living here that her father the Duke of York first started visiting the Harley Street-based Australian speech therapist Lionel Logue, as depicted in The King’s Speech). The 25 bedroom house was later destroyed by a bomb during the war, long after the Yorks had moved out.

As well as the house at 145 Piccadilly, the young Princess Elizabeth (and from 1930 her younger sister and only sibling Princess Margaret) also lived at White Lodge in the centre of Richmond Park in the city’s south-west. The Lodge, a Georgian property built as a hunting lodge for King George II, now houses part of the Royal Ballet School.

She also considerable time outside the city, staying in places including Scotland with her grandparents at either Balmoral Castle (owned by the Royal Family) or at Glamis Castle (owned by the parents of her mother, the Earl and Countess of Strathmore) as well as, from the age of six, at Royal Lodge in Windsor Great Park, the country home of the Yorks. The princess apparently had her own small house, known as Y Bwthyn Bach (the Little Cottage), in the grounds  – a gift from the people of Wales in 1932.

Following the death of King George V and subsequent abdication of King Edward VIII in 1936, new King George VI and his family moved from 145 Piccadilly to Buckingham Palace. Following the outbreak of World War II in 1939, the princesses lived in Balmoral, Scotland, and Sandringham but spent most of the war at Windsor Castle.

Princess Elizabeth, meanwhile, had met Prince Philip of Greece during the 1930s and in 1947, he asked for permission to marry her.
