A derelict 19th century townhouse on one of the main thoroughfares into King's Lynn has been rescued through four years of painstaking conservation work - and is being sold for £235,000.

Because of its architectural merit, King's Lynn Preservation Trust acquired the property at 90, London Road in 2009, after it had fallen into disrepair.

The trust started revamping the house in 2010 and the work was finally completed last year.

The property, which in the past has been divided into flats, has now been converted back to its original purpose as a single dwelling, and is being sold through Brown and Co in King's Lynn. It's believed to be under offer at £235,000. Its sale could enable the trust to choose a new project to support this year.

The property was unveiled on Saturday, and chairman of the trust Nick Balaam said: 'This was a challenging project but, despite some delays, the trust is delighted to complete it and even more delighted it is attracting much interest on the property market.

'King's Lynn has a rich historical heritage deserving protection and promotion. The trust plays its part by using its resources to acquire buildings of past architectural merit and - through careful conservation - make them fit for modern purpose but without compromising their original design and character - in other words using the town's heritage to good effect without losing it.'

The unveiling was attended by the Mayor and Mayoress of West Norfolk, North-west Norfolk MP Henry Bellingham, the leader of West Norfolk Council Nick Daubney, and Dr Simon Thurley, the chief executive of English Heritage.

The trust, which was established in 1958, has rescued numerous buildings of architectural and historic interest in the town, including the Greenland Fishery.
