A six bedroom home built without planning permission and described as driving a “coach and horses through recognised rules and regulations” faces the threat of demolition.

What started as a three bedroom home before conversion to a six bedroom mansion thanks to an extension, drew the wrath of East Cambs District Council.

A council spokesman said: “One of the possible decisions could be that the building has to be pulled down, but I cannot confirm that this will happen.”

A retrospective application by Richard Lee and Selica Sevigny of 9 Stretham Road, Wicken was refused by East Cambridgeshire District Council on October 14.

An officer’s report quoted one objector who said the “application drives a coach and horses through the recognised planning rules and regulations.”

Mr Lee and Miss Sevigny have the option to appeal, but for now the case has been handed to the council’s enforcement’s team who will speak to the couple and “make a judgement based on their findings”.

The council spokesman said: “Following the decision to refuse the retrospective application, the issue has now been handed to the council’s planning enforcement team who will look into the case and liaise with the applicant.”

The spokesman explained that Mr Lee has the option to appeal the decision but is now facing the prospect of his six bedroom extension being demolished, if his application is refused.

Mr Lee is one of the founders of the obstacle race series, The Spartan Race, who was forced to resign in 2013 as director, after his claims of serving in the Royal Marines were exposed as lies by an online group of former servicemen. The Ely man boasted of serving as a commando for three years, only leaving after breaking his leg. However, an investigation by the Walter Mitty Hunters Club, found he had only completed a brief stint in officer training in 2007, at the Commando Training Centre Royal Marines (CTCRM) in Lympstone, Devon.

At the time Miss Sevigny, who runs the Spartan Race series in Quebec and Ontario, backed his resignation.

Neither Mr Lee nor Miss Sevigny was available to comment on their planning application.
