London's Most Expensive Buildings

by Fitzroy of London

London has some of the most real estate in the world, with average property prices up to twice as much as those in the rest of the country.

Here are some of the most expensive properties in London which we have found:

Buckingham Palace

Estimated Value - £1 Billion

Despite competition from some of the mansions built from more recently acquired wealth, the official London home of the Queen is still the world’s most expensive residence, valued at a staggering £1 billion.

Built back in 1703 as a London a London townhouse for newly anointed Duke of Buckingham, the first royal to take up residence was Queen Victoria, who moved in around 1837. Since then, the palace has provided accommodation and principal workplace for whichever monarch has sat the throne.

With approximately 775 rooms to keep clean (including 1,514 doors and 760 windows) over 800 permanent members of staff are employed to tend to its upkeep, and it’s no surprise that the grounds are home to the largest private garden in the city. The sprawling 40 acre site contains a helipad, lake, tennis court and over 350 types of wildflower.

18 Carlton Terrace House

Estimated Value - £250 Million

While not in the same league as the 10 figure properties that are among the world’s most highly valued, 18 Carlton Terrace House on the outskirts of Trafalgar Square could well become the most expensive ever sold in the capital.

This six storey, 50,000 sq ft mansion was placed on the market as just over £250 million, and is said to be on sale on the mysterious ‘grey market’ – a secretive brochure is reportedly doing the rounds among the world’s most wealthy, showing pictures of inside the Grade I listed regency mansion that aren’t available to the general public. The secrecy is thought to be due to the security fears of the current owner.

30 St. Mary’s Axe (The Gherkin)

Estimated Value - £630 million

The first non-residential property on the list is one of the most iconic on London’s contemporary skyline. Built over a three year period between 2001 and 2004, the Gherkin is 251,000 sq ft of commercial office space situated right in the middle of the financial district.

One Hyde Park

Estimated Value - £1.15 Billion

The estimated value of this prestigious London address might be slightly misleading. One Hyde Park is actually a sprawling, luxurious residential complex in the heart of Knightsbridge that contains 86 separate apartments. The £1.15 billion figure is actually the cost to build the development, but with prices per apartment starting at around £20 million, the entire property is probably worth so much more than that now.
