Susan Wyndham's house in Spain is a rare mix of exuberance and elegance

At her holiday house in the mountains of southern Spain, English interior designer Susan Wyndham has brought together furniture, lighting and fabrics from all over the world to create interiors with an exuberantly layered aesthetic

An interplay of shades of green and pink unifies all the rooms in the house, including the main bedroom. The sofas in the drawing room, bought in England, are covered in a blue-green fabric by Marvic Textiles with pink printed cushions from Claremont. What appear to be greenish-hued tapestries on each side of the fireplace are actually facsimiles, printed on linen by Zardi & Zardi: they have a warming effect in winter without looking too opulent.

Life at El Ventorillo revolves around its main terrace. The colour scheme continues here and drifts into the garden: pink and white roses and scented geraniums surround a pomegranate tree, and the evergreen oaks stretch to the horizon. Above the banquette in the seating area, a mosaic roundel of mirror and green marble, commissioned from Emma Cornish in Tangier, commemorates 30 years of marriage. Chairs covered in grey-green and white stripes surround the table in the dining area, which is covered with a colourful Indian tablecloth.

Beyond the pool is the guest house with its old vaulted Mexican wooden ceiling installed by the previous owner. ‘The decoration here is an eclectic mix of fabrics, patterns and objects – Indian cobra wall sconces, sofas in pretty blue Colefax and Fowler printed fabrics and chairs, not yet re-covered, found at Lots Road Auctions in London as well as Chinese mirrors from Ronda and obelisk bookcases from my mother-in-law painted a dark brown by Fernando the gardener. People are frightened of throwing everything together but it often works.’ The result seems to be that rare combination of exuberance and elegance.

Susan’s lifelong heroine is Jane Digby, the 19th-century English aristocrat who led a life of adventure. A copy of her carved mahogany bed, by master cabinetmaker Jamie Orr-Ewing, brings a touch of fantasy to a spare bedroom. He also worked on the Moroccan cupboards and mirrored shutters in the bathrooms, which Susan designed. The house has been a triumph in every season, and at Christmas the family feasts on roast partridge and mulled wine on the heated terrace, to the sound of goat bells in the distance.
