Nestled in Huntingdon's Market Square is one of the town's historic gems - Walden House. Work is currently being carried out to restore the 17th century property, turning the building into flats. IAN MacKELLAR discovers more. RESTORING Huntingdon's historic Walden House to create six flats is costing more than £1million. If the attic floor of the 17th century Market Square building, with its magnificent views over the town centre, were also to be restored, the price tag would be even higher.
