Britain's most expensive streets are concentrated in Kensington and Chelsea, according to Lloyds TSB.
Seven out of the 10 most expensive streets in England and Wales are in the Royal Borough, with Campden Hill Square, in Holland Park, topping the list at £4,863,000.
Drayton Gardens with an average price of £4,428,000, Dawson Place at £3,891,000, Duchess of Bedfords Walk at £3,862,000 and Cadogan Square at £3,678,000 are also some of the priciest streets in the borough, according to the lender.
Elsewhere in London, Parkside in the London borough of Merton is the second priciest street in the country, with an average price of £4,826,000. Cedar Park Gardens in the borough also makes the top 10 with an average price of £3,596,000.
In addition, the most expensive streets away from London are mainly in the Home Counties. Properties on Leys Road in Leatherhead boast an average price of £3,108,000, the highest outside of the capital.
Outside of southern England, the most expensive street is Withinlee Road in Prestbury, where the average house price stands at £1,649,000.
Suren Thiru, economist at Lloyds TSB, says Kensington and Chelsea has "always had a glamorous reputation", attracting super-rich buyers from around the world.
"The area clearly has its attractions with excellent schools, upmarket shops, close proximity to the capital's business district and impressive properties. Other areas in the capital have similar qualities but property prices in Kensington and Chelsea tend to outperform the rest of London."
He adds: "Outside London, the areas with the most expensive streets are generally located well away from central areas, where buyers are typically attracted by larger properties and more green space."
The concentration of expensive streets in London further exacerbates the great north/south house price divide. House price data provider Acadametrics reports house prices in the capital rose by 3.1% in the 12 months to end November 2011, but in all other regions of England and Wales values fell over the same period.
In addition, property website Rightmove.co.uk says house prices in the South of England are now double those of the North and Wales, with this trend set to continue into 2012 and beyond.
