Hoppen is known for her signature neutral palette and trademark Perfect Neutrals, and is often referred to as the ‘Queen of Taupe’.[7] She has said of her design philosophy, “My philosophy has always remained the same. It’s about creating calm balanced environments based on Eastern cultures, i.e. order and creation of harmony. How people feel in a space is as important as the way it looks; one can’t be without the other to succeed.”[8]

In January 2014, she launched her first e-commerce store with a self-designed interiors accessories range. The same year the Daily Telegraph ranked her as the second most influential female interior designer in Britain.[9] In 2012, Vogue listed her among their list of 100 Inspirational Women and, in 2017, Evening Standard included her in their list of London’s most influential people. Kelly also appears on QVC UK, showcasing her exclusive QVC K by Kelly Hoppen range of jewellery and homewares.
