Jojo Barr


Born in London, Jojo Barr studied Interior Design at KLC School of Design in 2007. In 2014, she established House Nine Design. Under her watchful eye, her enthusiastic and highly capable team have completed a number of high end residential properties, large developments and hotel projects across the UK and overseas.

Jojo’s honesty & professionalism have attracted a very loyal following of exceptional Clients, on projects that span from residential refurbishments and new builds to key commercial and award winning hospitality fit outs.

She believes in a hands on approach to design, creating individuality in every new assignment, by applying vigorous research and understanding of the Clients brief as well as a deep understanding of the nature of the building and its surroundings, ensuring that no one project feels the same.

“I strongly believe in authentic, timeless design where warmth, honesty and informality are the basis for my practice and feed through into everything we do. I have a strong understanding of how interiors come together, from the architecture of a space to the furniture and soft furnishings that fill it. Each element is essential to creating one cohesive look that is both considered yet uncomplicated.

I get a huge amount of satisfaction from conceptualising a Clients brief and ensuring that they are made to feel completely at ease and confident in the process and that we will deliver to them a design that surpasses their expectations.“
