The lure of living within a stone's throw of the waterside has put three Westcountry streets in the region's top ten of pricey places to live.

According to the latest research by Lloyds TSB, two of the must-have addresses for the super-rich are on the lovely Roseland Peninsula in Cornwall, while a third is in the picture postcard Devon town of Dartmouth.

However, although house prices at the Cornwall and Devon locations top an average of just over £1.5 million, they remain substantially cheaper than parts of Poole in Dorset, where six of the top ten most expensive addresses are to be found.

In first place was the Sandbanks area on the outskirts of the town where a des-res in super-exclusive Brudenell Avenue would cost an average of £2.2 million.

The survey of the region's priciest streets found that a property in Restronguet Point, near Truro, is the third most expensive place to live and features an average house value of £1,552,000.

Freshwater Lane in the nearby picturesque village of St Mawes, is eighth on the list with an average house price of £1,288,000.

Meanwhile, the most expensive place to own a property in Devon – and taking the ninth place on the regional list – is Castle Road in Dartmouth where prospective homeowners would have to find £1,151,000 to get a foothold on the property ladder.

Andy Goundry, of Goundry Pearce Estate Agents in Cornwall, said he was not terribly surprised at the results of the survey.

"It's really not unexpected," he said.

"These are streets where there are big houses surrounded by big houses and all will have extensive water views.

"Most importantly, many of these very expensive properties will have direct access to the water and private mooring, which can be worth a premium of hundreds of thousands of pounds in a house price."

Nitesh Patel, housing economist at Lloyds TSB, said it was clear that properties on the coast were still attracting premium price tags.

"Unsurprisingly, the most expensive residential streets in England and Wales are in London, but it's also no surprise to see addresses in Sandbanks take the top spots in the South West, with Poole making up nearly half of their top ten," he said.

"The national survey shows that the most expensive streets continue to be tightly clustered in relatively small areas."
