In the upstairs drawing room, Beata installed a plaster hood and created a backdrop of Swedish Green marble for a display of beeswax candles. It is surrounded by artwork including a geometric painting on wood by Adriana Jaros (top left), an oil by Frank Walter next to the bust, a piece by Ugo Rondinone (top right) and a Jennifer Rochlin vase below a yellow light from Original BTC.

On the other side of the room, a bioethanol fireplace set in a black Formica cabinet was removed and replaced with a wall of bespoke joinery in toffee-coloured oak. A long; low section houses a record player and a corner cupboard conceals a fridge, allowing a desk to instantly morph into a drinks table. Unable to add a working chimney, but feeling that the room needed a focal point, Beata created a sculptural plaster hood above a panel of Swedish Green marble. In front of this is a cluster of beeswax candles that, she explains, in lieu of a real fireplace, 'creates a gathering place around fire. Lighting the candles feels like a bit of a ritual - there's something quite magical about it.' Also for this space, Beata commissioned an ottoman making use of a 1930 tapestry design by the celebrated early-20th-century Swedish textile artist Märta Maās-Fietterström: 'It was the first time that the weavers in the south of Sweden, where her designs are traditionally made, had ever done something like that. So it's a really special piece.'

Leaded-glass doors were installed to create a view from the front door to the back garden. 'It's a simple trick that helps you understand the depth of the house as soon as you come in,' says Fosca Mariani, Beata's head of interior design, who worked with her on the project. Down a black spiral staircase to the lower-ground floor, hung with an Isamu Noguchi paper lantern, is the owner's new recording studio, which has Josef Frank curtains and a bespoke sound desk. A spare room for guests on the same floor has sand-coloured seagrass on the walls and ceiling, and new wardrobe doors in green and ivory tadelakt. 'It is lovely because it has a bit of movement in it,' says Beata.

In the kitchen, the existing black cabinets have been softened by the addition of a wooden island with butterfly joints. Chunky rattan bar stools from Sane were chosen as 'something substantial and handcrafted to help counterbalance the black', she explains. This room has a skylight lined with sheets of brass. 'It was a bit of an experiment and in my head I was prepared to change it back at my own expense if it looked awful. Luckily, it works beautifully. It gives an amazing glow and reflects the wildflowers that we planted on the roof above.'

Opposite the kitchen is a play area. A buttery-yellow cabinet inspired by a Le Corbusier design is used for storing toys, and a low Japanese tea table is ideal for puzzles and Lego. "There's nothing childish about it,' says Fosca. 'Everything can be swiftly put away when the children go to bed, so the room feels sophisticated and grown-up again.'

The Roche Bobois 'Mah Jong' sofa in green velvets from Romo, Abbott + Boyd and Colony is brightened by cushions in Claremont, mohair velvet and Studio Atkinson ticking in the downstairs living space. An antique textile on the wall conceals a television. Floor cushions from Futon Tokyo and Etsy are arranged on a hemp rug around a scorched-ash table.

The owners came to the project with a few pieces of their own, one of which was a Roche Bobois 'Mah Jong' sofa. 'It's not something I would naturally gravitate towards, but I actually love the 1970s conversation-pit vibe it brings to the room,' says Beata, who had it reupholstered in tonal green velvets to echo the colours of the garden. A widescreen TV is concealed behind an antique textile on a curtain pole.

Upstairs, in the main bedroom, Beata wanted simplicity and softness'. The walls are in a very light blue, with textiles providing the vehicle for colour. Behind the headboard is a patchwork from Belgium, while on the bed is what Beata calls 'the loveliest blanket in the world', in baby-soft green cashmere. Every detail is finely tuned for comfort and pleasure: 'I think we work quite well with musicians. I've always felt decorating is a bit like songwriting. Rooms are essentially compositions, often collaborative. You need harmony, but you also need a little discord'
