Royals give behind-the-scenes look during Buckingham Palace renovations

The royal family is giving the world a sneak peek inside Queen Elizabeth II's home as it undergoes renovations.

In a series of videos and photos shared to the royal family's Instagram page Monday, people got a behind the scenes look at some of Buckingham Palace's facelift.

One video showed a hallway in the iconic building lined with construction lights and noted that "reservicing" was an ongoing project at the iconic building.

"Helping to make the building more energy efficient and cost effective," one slide read.

A few other clips showed old cigarette boxes and newspaper clippings dating back to the 1950s were found during the renovations.

The iconic structure is in the end of its second year of a 10-year project after a Treasury report concluded the building’s infrastructure was in danger of a catastrophic failure.

Videos also showed lifted floorboards which were removed to "investigate ahead of reservicing pipes and wires."

The Palace's electrical wiring, heating and plumbing hasn't been updated since the 1950's, according to Buckingham Palace.

The total Sovereign Grant, which funds Queen Elizabeth II and her household’s official expenses, was 82.2 million pounds (about $104 million), or 1.24 pounds per person in the U.K. That figure includes 15.2 million pounds ($19.3 million) set aside for future phases of the palace renovation.

The palace says the royal family took on 3,200 official engagements during 2018-19 and welcomed 160,000 guests to events at the royal palaces, including Buckingham and the other properties.

The palace serves as grounds for royal events and important state visits from foreign leaders. Prince Charles' 70th birthday patronage celebration, which Duchess Meghan attended shortly after her wedding to Prince Harry was held at the palace.

While Buckingham Palace has accommodated United States presidents in the past, President Donald Trump wasn't afforded that same privilege due to the renovations.

During his 2018 visit, Trump stayed at Winfield House, the residence of the U.S. ambassador (Robert "Woody' Johnson is Trump's ambassador to the Court of St. James's) in Regent's Park, commissioned by American socialite and Woolworth heiress Barbara Hutton in 1936.
