IAN MacKELLAR DESECRATION of one of Huntingdonshire's oldest buildings? Or a loving restoration of a 16th century family home? That depends whether you ask the owner or his next-door neighbour. At the heart of the row is Melviors Hall, in Earith High Street, a Grade II* listed building that was bought by Peterborough electrician Justin Carter last month. His next-door neighbour Samantha Mack, who runs a safety-manufacturing business in the village with her partner Simon Blackmore, and lives with him and her two children at number 89, accuses Mr Cater of desecrating the hall, demolishing a conservatory without consent and building a car park where, until last week, there stood an established orchard.
