It has long been considered as one of the most sought after areas in the Midlands.

With stretches of private roads, surrounded by masses of greenery and private parks, Four Oaks in Sutton Coldfield has always been one of the region's prime locations.

Now the area has been recognised as the location of two of Britain's most expensive streets with average house values hovering near to the #1.4 million mark. Featured in the Mouseprice.com street rankings 2007 national tables, Luttrell Road and Roman Grange, both in the B74 area, ranked 11th and 12th respectively.

The poll was prepared by the property data website and was based on Land Registry sale price statistics that had been updated with details from estate agents.

The survey found the average street value of Luttrell Road was #1,350,283 and #1,267,288 for Roman Grange. It also looked at individual counties to identify the 20 most expensive streets in each region.

A spokesman for Mouseprice.com said the B74 postcode was the most expensive in the Midlands.

"The Sutton Coldfield area, to the north of Birmingham, dominated the top of the rankings, with Luttrell Road as the most expensive area with an average property value of #1,350,283," he said. "Roman Grange, Squirrel Walk, Jervis Park and Roman Road, also in B74, all appear in the top 10 most expensive streets in West Midlands.

"The West Midlands' most expensive property tends to follow two significant trends. Either, as with B74, it centres on the suburbs of Birmingham. Or the survey shows the wealthy residents of the region living in much more rural surroundings."

A spokesman for Hunters Estate Agents in Four Oaks, Sutton Coldfield said the findings came as no surprise as they were situated in a very affluent and high-profiled area.

With its easy transport links to the motorway and to Birmingham city centre, the area is well known for attracting parents, who hope their children will be able to attend nearby schools.

"Four Oaks is very leafy and green and you can't see anything of the properties in the summer for the bushes and trees," he said. "Luttrell Road is off Four Oaks Road. It is considered to be a sought after area. It is an area with big, expensive properties.

"The station is very nearby at the bottom of Four Oaks Road and the shops are close too.  We have noticed that people are moving to the area for their children to go to Arthur Terry and primary schools in Four Oaks."

He added that Roman Grange, a private road in Four Oaks, was near to the popular Roman Road and Streetly Lane.

"There are all sorts of private roads with gated properties down there. They are mainly bungalows and detached properties."

Kensington Square, in the borough of Kensington and Chelsea, came top of the table with an average property price of #5,534,480.
