It all started when…

“I fell in love with Art History at boarding school and decided to continue to study it at Christie’s Education in London. During this time, I discovered a passion for contemporary design when I worked for David Gill in his incredibly inspiring St James's space. In particular, I was completely mesmerised by the designs of Mattia Bonetti and had the pleasure of working with other artists such as Barnaby Barford and Zaha Hadid. I then studied Art Business with Sotheby’s Institute where I expanded my knowledge base in art markets, emerging markets, contemporary design and art; essentially all things 'art business.’ I now love working with emerging artists, designers and craftsmen on Decor A List, helping clients furnish a home as unique as they are and help clients with their first art collection or expand their existing one.”



Based between London and Canada, Catherine brings clarity and quality to each project to ensure your requirements are met in a smooth, enjoyable and transparent manner. Known for her expert colour selection and pairings of traditional shapes with modern art and accessories, Catherine often incorporates clean, tailored lines and punches of tasteful patterns in her interiors blurring the boundaries between design, art and interiors.

Promoting the importance of wellness in design, Catherine’s attention equally revolves around holistic design to ensure form meets function not only in an attractive manner, but in a way that is beneficial to your overall wellbeing.

Considering factors such as natural light, storage, natural materials, air quality, ergonomics and most importantly how you feel in a space, holistic design ensures that your home is responsive to your needs, behaviours and requirements, while being tailored in a way that is unique to you.

Catherine's interest for art and interior design has never been far from her heart and her education at Christie's Education and Sotheby's Institute, as well as her extensive experience within the art world have heightened this passion to where she is today.

Working with an array of clients in the UK and globally, Catherine specialises in bespoke interiors, complete renovations, custom furniture design for truly one-off pieces as well as the sourcing of Fine and Decorative Art. She helps her clients expand their collection, start their first one or design a unique space that encompasses the arts.

Catherine’s eponymous global luxury interior brand, Decor A List, is known for its global designs, promotion of craftsmanship and sophisticated style pioneered by Catherine herself. Decor A List's breadth spans from limited edition furniture, original art by contemporary artists and home furnishings ranging from luxe bedding, fine china, accessories, wall coverings, lighting, rugs and objets d'art. Very much echoing Catherine's signature style, she has juxtaposed raw with refined, old with new, and sophistication with pizazz; effortlessly blending pieces and artworks from diverse periods in one curated space.

Your home should tell your story in a curated manner where art and design exist effortlessly in harmony to promote comfort, aesthetics and wellness.
