Residents overlooking a controversial house being built in Clayton have vowed to go to the planning ombudsman if their pleas to get it pulled down or drastically down-sized are ignored.

Neighbours in Sandringham Road have made an official complaint to Bradford Council, accusing officers of not doing enough to make sure the developer of the mansion-style house sticks to his plans.

A fresh planning application was submitted earlier this month after a number of planning breaches came to light as the property was being built. A decision is pending.

A spokesman for Bradford Council said the views of local residents and other interested parties would be “taken into consideration during the planning process before any decision is made”. But resident Pam Cunningham was not convinced and said: “We are not going to give up on our campaign to put a stop to this complete eyesore.

“We are currently going through the Council’s complaints procedure and have stepped it up by putting in a formal written complaint. The next stop will be the ombudsman. The whole situation is farcical.”

Ian Horsfall, the Council’s planning manager, had already confirmed to the Telegraph & Argus that site visits had been carried out. A number of changes, not shown on the previous planning bid and granted conditionally in 2012, had been identified. The applicant and agent had been told to put in a new planning application that, if approved, would authorise those changes.

Planners had previously rejected permission for a 13-bedroom house on the site and planning records show five other sets of tweaked plans were then re-submitted until the scheme with seven bedrooms, a playroom and study, a games room and a detached double garage was approved last summer.

Residents say building work has been making their lives a misery and has forced them to make countless calls to planners, Council enforcement officers and health and safety officials.

Complaints include the house not being in character with the surroundings, overshadowing homes and having clear glass in some of the windows which planners said should be frosted.

Mrs Cunningham said: “We still don't think this is going to be a normal house – it’s an ugly, new mansion.”

House owner Jasinder Singh could not be contacted for comment.
