We’re Helen and Simon Knox, co-founders of Lewis Knox Interior Design.

We set up this independent design studio together to practice innovative client-focused design. Interior spaces affect us all, and good design has the power to enhance people’s moods and well-being. That’s why our approach is all about creating personal and highly imaginative interiors, tailored to fit the needs of each individual project.

Having both spent more than a decade working in high-end interior design, we decided to combine our skills and start a new design studio. Along with our dedicated team, we have in-house expertise in technical architectural design, interior styling and soft furnishings. This means Lewis Knox offers a complete service for both residential and commercial properties.

Doing things differently

Too many interior designers are inflexible with their style and care more about the place they are working on than the client’s happiness. We think it’s about time this changed. Our design philosophy is to use our skills and expertise to unlock the vision of our clients and push their boundaries to explore what is possible within their space.

Doing things differently - Lewis Knox

What we do

It’s simple. Our focus is to create the ideal interior design to suit any space by working closely with our clients and listening to them carefully. Only then can we achieve a result they are guaranteed to love. Collaborating with people to take their influences and tastes on board is one of the most enjoyable aspects of our work in interior design. We like to open minds to innovative ideas and help find the perfect look. Our ‘signature style’ is to bring out our clients’ signature style, even if they’ve not discovered it yet.

What We Do - Lewis Knox

How we work

We understand that every client is unique and are committed to creating a bespoke interior design to suit each space that we work in. Whether it’s a small residential home or a large-scale commercial project, we believe that regular communication throughout the process is key.

Our aim is to get to know you, build a rapport, and create a relationship that makes the whole experience enjoyable and relaxed. We will open your eyes to new possibilities and concepts, but never force you in a direction that you don’t want to go. In short, we make it possible for you to imagine your ideal interior and use it to create your perfect space.
