A centuries-old ducal estate in Suffolk brought up to date by the latest generation

Having worked in the music industry internationally, Harry Grafton returned to Suffolk to become the custodian of Euston Hall in 2011 and found the house in need of revival. Since then, he and his wife Olivia have turned it into a family home and founded the Red Rooster festival in the grounds

In the drawing room, David Seyfried sofas in charcoal 'Spencer Velvet' from George Spencer Designs and cane chairs with seats in a Marvic Textiles flamestitch are teamed with an ottoman made by AT Cronin Workshop to a design by Woody Clark. Walls in a custom blue by Papers and Paints set off gilt-framed paintings, including a portrait of the 3rd Duchess, Anne Liddell, by Joshua Reynolds.

'While we waited for planning permission, we started on the garden,' says Olivia. They commissioned Justin Spink to create a new design, and then worked on dredging five miles of river and the overgrown waterways. They later built what is known as the River Shack, which houses a sauna, and guests can cool off afterwards by jumping into the - now limpid - river. Harry also set about converting the estate and farm in line with environmental principles, including heating the house on a sustainable basis.

Their boundless energy and commitment have driven a long project. 'We had to get it right: this was our one chance,' says Harry. A tip-off led them to Woody Clark, the below-the-radar interior designer who has worked on some of Britain's grandest houses. 'This is Harry and Olivia's home, their project, their hard work,' says Woody. 'I don't impose - I just show what is possible.' He was constantly on-site, advising, encouraging and solving problems. Even ducal projects are not immune from building complications.

A bust of the 6th Duke is displayed beside the bookcase in the library.

'We were fortunate to have an incredible education from Digby and Woody on the palette and detail of the 17th and 18th centuries - from flamestitch fabrics to the right type of screw (no crossheads) and the width of a floorboard,' explains Olivia. 'Ian Block of AT Cronin, who did a huge amount of the upholstery, also played an integral role,' she adds. 'We moved into a flat in the courtyard for the two and a half years of core building work, and another year was spent decorating and picture hanging,' recalls Harry. 'During that time, we had two of our three children.'

In the new entrance hall, a child's scooter leans against the door leading to the inner hall, which has a magnificent portrait of Charles I by Van Dyck, the counterpart of a version in the Louvre. After dark, the glossy sea green wallpaper in the small dining room nearby glows in the candlelight reflected by Goan mother of pearl sconces. The needlepoint curtains were cleaned and reused, and were given new hems, with deep borders added to replace the damaged sections. For the curtains in the formal dining room next door, bespoke fabric specialist Humphries Weaving produced a durable silk-and-wool combination to ensure longevity. Here, too, royal ancestors line the walls.

Hydrangeas and climbing jasmine, and roses frame the door from the garden into the room below.

‘We wanted more female portraits in the drawing room’, says Harry, of their decision to relocate artwork with help from Jonathon Miles of Cambridge's Trumpington Gallery. The blue of the walls was mixed to complement the gilt picture frames and red coronation robes of Anne Liddell. the 3rd Duchess (though she contracted measles and did not attend George III's 1761 coronation). David Seyfried sofas are covered in 'Spencer Velvet' by George Spencer Designs, which Olivia describes as 'very practical'.

The ballroom and library were lost in the 1902 fire, but Harry and Olivia decided to unite the remaining books in a new library with bookcases in the Kentian style, designed by Digby Harris with Silvanus of York. Appropriately, this room overlooks William Kent's final work - a folly known as the Temple. Each year since 2014, around 8,000 visitors have attended Euston's Red Rooster music festival, with many pitching their tents next to Kent's Temple. (As part of Euston's efforts to diversify, the Temple is also available to rent for short breaks.) This celebration of Americana, Blues and Roots music holds great significance for Harry. He is an accomplished guitarist and the organisational skills he developed during his time with The Rolling Stones have driven the event's growth and ensured its success.

Inside, 19th-century French needlepoint curtains are complemented by Zoffany's 'Metallo' verdigris wallpaper. A collection of armorial china, including pieces made for the 3rd and 4th Dukes, hangs alongside family portraits by Sir Godfrey Kneller and Sir Peter Lely.

The decoration rule adopted for the upper floors of the house was simple: smaller, darker rooms like bathrooms would be wallpapered, and larger rooms like the Arlington bedroom - traditionally used by royal visitors - would be painted. The top floor, once neglected, now has a row of pretty bedrooms. Harry and Olivia's bathroom on the floor below is particularly striking. It was designed around a pair of gargantuan Victorian oil lamps found in the stables; these sit in niches created around a very deep bathtub. Harry's ideal, however, is the Arlington bathroom, with its record player, vinyl selection, whisky decanter and small library of musicians autobiographies. One could imagine the late Queen Mother, a frequent visitor, dipping into Johnny Cash's oeuvre, on the page or the disc.
