Help restore one of Twickenham's greatest treasures by donating a collectable item to High Road Auctions' charity auction during Twickenham Festival.

The Heath Road auctioneers hopes to raise funds to help restore Sandycoombe Lodge, in Sandycombe Road, a country home built and lived in by artist JMW Turner.

Among the lots already promised is a drawing by World War II artist Felikes Topolski and a 1790s watercolour of the Thames at Brentford.

Turner's House Trust chairman Catherine Parry-Wingfield said: "We have been generously supported by private and institutional donors, as well as many pro-bono hours donated by our wonderful volunteers.

"We just need to get the final slice."

In order for restoration work to proceed, the trust, which has already raised more than £2m, must find an additional £250,000.

High Road Auctions branch manager David Holmes added: "High Road Auctions is delighted to be hosting the charity auction to benefit Turner’s House Trust as part of the Twickenham Festival.

"We hope it will be a fun event in support of a worthy cause and we look forward to welcoming everyone to our saleroom."

Auction donations should be delivered to High Road Auctions, 55-61 Heath Road, smaller items from June 9 smf larger items such as furniture from June 16.

All items should be delivered by 6pm Wednesday, June 17, and the auction takes place at 2pm on Sunday, June 21.
