Prince Charles and Princess Diana’s home may have contributed to the tensions during their married life.

According to royal author Sarah Bradford in her book “Diana,” the Prince and Princess of Wales’ home in Kensington Palace, popularly known as KP, was very small. An insider felt that the couple’s home contributed tensions in Prince Charles and Princess Diana’s relationship.

“I think the apartment contributed to certain tensions, they were on top of another as regards what they were supposed to be doing,” one insider told the author.

The said building “was less a home than a prison” for Princess Diana. One member of the staff also told Bradford that it was just a small apartment and it needed to be bigger.

“They had a sitting room and a study each, then a drawing room, then a dining room and that was it really, as far as reception rooms went. Not a lot of corridor space, so it wasn’t very comfortable,” the staff said.

“They needed a second reception room downstairs so that upstairs would be private, but the way it was it was all in together. They should have moved initially to somewhere bigger.”

Patrick Jephson, Princess Diana’s private secretary, confirmed the feeling of oppression and smallness in the said home. He was “surprised to find the apartment smaller and gloomier than he had expected.”

In addition, it was difficult for the couple to keep their privacy because “everybody could hear everybody else,” according to Jephson. “If you needed to get away from someone there was just not enough space,” he added.

Meanwhile, Robert Lacey believes that if there’s something or someone to blame for the Prince of Wales’ failed marriage to Princess Diana, it would be himself. Even his own parents blamed him for it.

“It would be a great mistake to say [the Queen] blamed Diana for what went wrong,” Lacey said in the documentary “Princes of the Palace.” “If anything, I believe, that she and her husband Prince Philip put more of the blame on Prince Charles, and Prince Charles of course, as we since discovered, was already committed emotionally to another woman.”

Princess Diana said in her past interview that her marriage to Prince Charles was a bit crowded as there “were three of us,” hinting at the future king’s affair with Camilla Parker Bowles. Prince Charles and Camilla wed years after the death of the People’s Princess. The Duchess of Cornwall is set to be queen consort when the Prince of Wales take over the throne.
