The retreat was designed by the actor’s architect Ben Pentreath, who is a favourite of the Royal family. He previously helped King Charles design the experimental village of Poundbury in Dorset, and also redesigned the Middleton family’s Chelsea flat.

It will be mud and kids climbing trees. London at the weekends can feel very destination-driven. I want peace.’The pull of the countryside is natural for Rosie. She grew up in rural Devon, a life which she described in Vogue as ‘rustic, outdoorsy, wild, simple’, adding: ‘Home was a cottage on a couple of hectares with animals everywhere.’She said: ‘There was tack being cleaned in the back kitchen, usually some animals – a bird Mum was trying to bring back to life.’ ‘Mum has dogs everywhere and muddy boots, and it’s perfect for them. The house is completely untidy. They live a bucolic life – very bohemian.”We lived within our means; we had enough,’ she added, ‘Mucking out the horse every day, school uniforms ironed by me. It instilled self-sufficiency.’ She said she tries to instill a similar sense of gratitude in her own children today. ‘It’s a fine balance; they’re still little,’ she said, adding that her mother used to tell her: ‘Life’s not going to hand you things on a silver platter.’
