Director Richard Douglas said: "We anticipated there would be differences in the property market from 80 years ago.
"However, the extent to how much it has changed is surprising. We knew Mayfair would remain at the top of the board and Old Kent Road at the bottom, but the areas that have moved in between are eye-opening.
"Fleet Street, which has always been a prominent central location in London, has dropped down to the blue area of the board with an average value of £611,000.
"The way London has evolved and grown has had a significant impact on which areas have flourished. We are certain London will continue to change over the next 80 years."
