“A good interior is the perfect mix between the use of the building’s architecture and the personality of the people who live there,” he says, meaning that you should work with the strengths of the building’s existing features, rather than fighting against them, and add your own creative vision on top. So if you live in a Victorian terrace make the most of the high ceilings and period features – if you live in a modern apartment, built like a square box, hit it with some punchy colours and treat it like a gallery space in which to show off your furniture. As one of House and Garden’s 100 Leading Designers, Staffan describes his filmic style as “a mix of Asian and Scandinavian functionalism, combined with a strong appreciation of furniture as sculptural art.” Lights, camera, and a lot of action.

Designed by Staffan for a client, this property in Kensington revolves around the huge sofa. “The sofa is a large part of any interior, as it takes up so much space,” Staffan says. “It should always be one of the first things you think about – everything else can fall into place around it.” Its Perspex base makes it look like it hovers, and its armrest, acting as a bookshelf, is a clever way of adding extra storage. The greys were a way of warming up the modern space. “Grey is my favourite colour because if you get the right shade, with hints of brown tones in it, it suddenly becomes so friendly and inviting.”
