Part of an 18th century garden could disappear underneath housing because no-one realises its importance, according to an expert.

Landscape gardener Kevin Nether believes the grounds of Hatchford Manor, off Ockham Lane, Downside, contain unique and valuable trees threatened by development.

But councillors say they are working with Latchmere Homes to secure the future of the house and all valuable trees will be preserved.

Latchmere has planning permission for five deluxe houses at Hatchford. It is asking Elmbridge Council for permission instead to build three or four houses elsewhere on the site.

Mr Nether believes part of the gardens, known as the Pinetum, is at risk.

He said: "The garden dates from 1703 and there has been a building on the site for more than 600 years. Now they want to put houses there."

He believes the gardens contain at least one champion tree - the oldest and largest known member of the species in the country.

"There are cedar trees which are at least 300 years old. There has been some cutting and the garden was hit by the hurricane of 1987.

"But even so there are some beautiful specimens. I believe they include at least one champion tree.

"It is a Tsuga Canadensis Pendula which is a North American variety of hemlock.

"I have checked my identification with Kew Gardens, who say it is correct."

He is not aware of any other champion trees within the borough boundaries.

He said: "I am trying to protect the heritage of the county. I was brought up in this area and I cannot watch them bulldoze it away."

Richard Eshelby, of Latchmere Homes, added: "One individual is intent on causing us trouble and his allegations are without foundation.

"Not a single valuable tree will be cut down and most residents seem to support our revised plans."

Surrey's historic gardens officer Brenda Lewis said: "Consent for this scheme was given by Elmbridge Council.

"Sadly very few of the trees from that period still exist - only three or four specimens.

"It is sad that planning permission has been given and the garden will no longer exist. But members of Elmbridge Council took this on board when they made their decision."

She said planning permission for houses had been given subject to conditions on the restoration of the house and gardens.

Cobham and Downside councillor Dorothy Mitchell said she was looking forward to seeing the house and gardens restored to their former glory.

She said: "Latchmere is going to some lengths to restore the property and residents are very excited about it. "I have been shown round the building, and it was extremely interesting, although very badly damaged in places.

"I look forward very much to seeing what can be done with it."
