Laurence Llewelyn-Bowen has made no secret of his disdain for boring paint colours, particularly the trend he has dubbed "the grey-naissance".

His local council has other ideas.

The interior designer and Changing Rooms presenter has been ordered to paint the doors and window frames of his Cotswolds studio in Dulux grey.

The studio is a modern annexe to his Grade II-listed manor house in Siddington, near Cirencester. The shade that he must use is Dulux Flake Grey, a trade paint.

Writing earlier this year on the £500m sale of Farrow & Ball, Llewelyn-Bowen poured scorn on the company’s muted colour palette.

"How extraordinary that the British public is willing to fork out £84 for a five-litre tin of washed-out colour called ‘tallow’, ‘drop cloth’, ‘off white’, ‘clunch’, ‘lamp room gray’, ‘blackened’ or ‘pigeon’," he wrote .

"Their paints are everything an 18th-century duchess would despise. They are – oh, the shame – the colours of the servants’ quarters."

Lamp Room Grey and Dulux’s Flake Grey are very similar.

Llewelyn-Bowen previously said that grey reminded him of 1980s office spaces, arguing that it worked only when paired with bright, jewel colours.

"On its own, grey is so ridiculously and unbearably drab," he said. "When you’re just using grey on grey on grey, the only thing you’re lacking is a photocopier in the centre."

In response to the planning application, Cotswold District Council decreed: "All new joinery shall be painted in the specified Flake Grey colour within one month of its installation, unless an alternative finish is submitted to and approved in writing by the Local Planning Authority.

"It shall be retained as agreed thereafter.

"This is to ensure that the development would be appropriate to the building, which is listed as being of architectural or historic interest, thereby preserving the special architectural or historic interest which it possesses."

Planning officers said the outbuilding needed to be in keeping with the main 16th-century manor house, with "sympathetic materials and details".

The historic home was previously owned by John Roberts, a founding member of the Quaker movement who fought with Oliver Cromwell during the Civil War.

Llewelyn-Bowen has brought his singular style to the inside of the house. He has described his "magnificent homestead" as "the most rock’n’roll 17th-century manor house in the Cotswolds", with "pimped-up" kitchen in which "you could imagine Elizabeth Taylor or Joan Collins making a cocktail".

Changing Rooms is being revived for the modern era by Channel 4. It will appear later this year with Davina McCall as presenter, and Llewelyn-Bowen among the designers.

Asked in a recent interview to sum up his style, Llewelyn-Bowen said: "Whatever I am doing, it has an emphatic va-va-voom about it. I’m never going to be pitching for the same job as Kelly Hoppen."
