behind bonba

Kika Estarellas

Architect and Co-Founder of BONBA studio_WELL AP

Kika brings fifteen-plus years of experience as an architect and interior designer to the table. She is passionate about creativity and the relationship with her clients, perhaps owing to her fascination with cooking and the connections that happen around a table. Her experience working at studios in Barcelona, Paris and London has given her a broad perspective on design.

She doesn’t shy away from colour, and she dislikes boredom.

She is driven by a passion for creating timeless spaces that make a life well lived possible.

Alex Llusià

Architect and Co-Founder of BONBA studio_ PGDip REHAB

Alex is an architect and co-founder of BONBA studio. With over fifteen years of experience as an architect at his back and following stints at studios in Barcelona, Madrid and London, he has discovered that he is passionate about every aspect of design and how every image, object and space can make an impact on people’s lives.

He thrives on being both conceptual and pragmatic. He has a keen interest in the finer details of design and is involved at every stage of the process to ensure that the designs he creates are fully brought to life.

Self-criticism is his best friend, and he loathes the word trend.
