Bell used cost-effective materials including MDF for the folding doors to the studio, sliding panels, kitchen-cupboard doors and extensive fitted shelving and storage cupboards. 'Sometimes a budget is a good thing - it forces you to concentrate on what is important,' she says. 'For Londoners, space is a luxury in itself and I prefer to maximise my area rather than pay for expensive materials. A poured resin floor, for example, is less expensive than quality concrete - and a lot cheaper than limestone,' explains Bell. Other materials used include jarrah (eucalyptus) wood for worktops, unglazed white tiles in the kitchen and bathroom and stainless-steel fittings - taps and door handles. Painting the original red bricks with white paint adds vital texture and contrasts with the smoothness of the flooring. Installing a new ceiling conceals electric and audio wiring as well as the awkward beams. Now all is harmonious matt white with a shining floor and lots of light. Despite the architectural interior, Bell swears it's a surprisingly easy space to work in. And the best thing? 'After a hard day at the office, you can shut the door and leave your work behind you.'
