A higgledy-piggledy country house in Hampshire harmonised by Salvesen Graham

Interior design duo Salvesen Graham are known for creating classic, calm and comfortable rooms. Their signature style and attention to detail have brought a welcome feeling of harmony to this formerly disjointed country house in Hampshire, providing the perfect setting for family life

Reflecting changes and additions made over the course of several hundred years, the house has elements dating from the early 17th century, the mid 19th century and the late 20th century, and these needed to be united into a cohesive whole.Christopher Horwood

Less obvious was what to do in the dining room, directly off the main entrance hall, which has the same style of wooden panelling. It also has an ornate, rococo plaster ceiling. Despite these historic and slightly heavy architectural elements, the room feels remarkably fresh. This is in no small part thanks to the panelling having been painted in a muted shade of light green. 'It's not something that we would normally have done, but it stops the room feeling like a gentlemen's club,' says Mary. ‘And instead of being some dark space in the middle of the house, this has become a room that you could just as happily be in for lunch as for dinner.'

Though it is not immediately obvious when you visit the house, upon reflection, there are lots of decorative details and layering. 'It was through colour and fabrics that we were able to create a softness and harmony that meant you didn't feel like you were jumping around from room to room.' Nicole says.

The kitchen and breakfast room is a case in point. This is a large space and an important part of the house, but it needed to feel warm and inviting. 'There had to be somewhere three boys could be fed and their friends entertained,' says Mary. A combination of walls painted in Edward Bulmer's ‘Cinnamon’ and covered in a Phillip Jeffries grasscloth immediately softened the utilitarian feel, as did blinds in a pretty print. The breakfast room area - formerly an orangery with multiple gothic-arched windows - has been completely reimagined. Today, it has a farmhouse feel and that is not just because of the simple, country style of the dining table and the ladder-back chairs on top of an antique rug. The gothic arches were squared off; heavy white-washed beams were added to the ceiling; and a chimneypiece was installed at one end. As Nicole explains, these clever architectural tricks, 'bring the room back into the house, rather than it feeling like an extension that runs into the garden'.

What has been achieved is quite remarkable. The Salvesen Graham designers have not changed the essence of the house: it is still a building comprised of distinct parts. And those transitional spaces that mark the evolution of the house are still visible. What is different is that they have been softened and blended, giving it a sense of harmony.

The drawing room walls in Edward Bulmer Natural Paint's 'Jonquil' and curtains in 'Sevres' cotton from Fortuny provide a background for comfortable seating. This includes bespoke sofas covered in Robert Kime's 'Opium Poppy' linen, a pair of David Seyfried's 'Salvesen Graham' chairs in Claremont's 'Milano Linen' and an armchair reupholstered in Salvesen Graham's 'Genevieve' cotton mix weave. On the console table in front of Chloë Lamb's Beachcomber oil painting, a metal agave leaf table lamp has been teamed with an ‘Ashoka Stripe’ linen shade from Robert Kime.

This can also be felt upstairs, where eight bedrooms are found off rambling, interconnected halls. One significant change here was the creation of a wonderful enfilade of rooms, which sees the owners' large main bedroom connected to a generous bathroom via a dressing room. Mary laughs as she says, 'I think we're probably getting known for giving clients really lovely, massive main bedroom suites, and that means there's usually a guest bedroom that meets its fate at our hands.' In this case, the sacrifice was justified: it is a luxuriant space, packed with pattern and impossibly charming.

The bedroom is also the perfect spot to take in the views of the rolling Hampshire landscape that surrounds the house (there is even a window seat to encourage this). Deep in the heart of the English countryside, this is a house formed over several centuries that has been gently ushered into the modern era in a way that feels so right.
