The lifestyle division at The Communications Store will lead on the long-term programme, including media relations, ambassador alignments, and digital and design consultancy. The team will also oversee The Conran Shop's activity during the London Design Festival this September.
The Conran Shop was founded by Sir Terence Conran in 1974. Over the past three years the business has been given a new direction by chairman and creative director Jasper Conran. The shop has stores in Chelsea and Marylebone in the UK, and Paris and Japan overseas, selling furniture, lighting, home accessories and gifts.
The Conran Shop said: "The Communications Store’s experience, contacts and reputation in the lifestyle and design space will prove invaluable to us as we seek to move forward."
The Communications Store said: "The Conran Shop is a brand we have admired for many years, first under Terence Conran and more recently under Jasper’s innovative creative direction."
