The estate agent's view

Ty Gwyn Avenue

Ramzy Bancroft, Head of Sales at estate agent Jeffrey Ross, said: “It is not surprising Ty-Gwyn Avenue came out on top.

“The area is very affluent and people rarely move because it’s a good balance between being close to amenities, shops, schools, parks and links to main roads.

“Only residents would drive down there and a lot of the houses have been developed and extended.

“Only a handful of houses have been up for sale there in the past five or six years.

“Around six years ago they were sold at around £500,000 to £700,000 and now they would be more than that and, percentage-wise, most of them would be over a million.”

'It's a gorgeous road'

Helen Davies, Head of Sales at Moginie James added: “Ty-Gwyn Avenue is a gorgeous road and there are a few similar roads that run parallel to each other around there.

“It’s a very desirable area and it’s mainly families that live on that road.

“All the houses would have at least four bedrooms and they have big gardens.

“Every house is individual and it is very pretty and quiet there. It also falls in the Cardiff High catchment which adds to the value.”

According to Zoopla the most valuable street in Britain was Kensington Palace Gardens in London where the average house is worth an incredible £45.4 million.

The most valuable town in Britain was Virginia Water in Surrey where the average house is valued at a cool £1.29m by the property website.
