Function has to come first, so plan to make sure everything physically works in a room. It’s the same with choosing furniture. In the past, I’ve learned the hard way and chosen chairs that look incredible, but are really uncomfortable. If they’re going to be used a lot, they must be comfy. Coco Chanel once said: ‘Get dressed, then take one thing off’, and the same rule applies to interiors. People have a tendency to overwork things, but sometimes, simple is better. Lighting can play a huge part in the feel of a room. When it comes to bedrooms, I prefer a central, decorative pendant light layered with small side lights and floor lamps. Downlighting can create quite a stressful space.
