Our Story

Theodorou - Thelliez is a boutique design consultancy based in London. With a passion for creating spaces that evoke deep emotions and offer rich experiences, each project is a testament to our commitment to timeless design, where every element is thoughtfully considered and meticulously curated. 

Strongly focusing on composition, texture, materiality and artisanal savoir-faire, we strive to create spaces that surprise and delight at every turn, offering moments of discovery that engage and enchant guests throughout their journey. 

With over a decade of experience in high-end design and a background at Foster + Partners, we bring a sophisticated perspective to our work enhanced by a strong architectural discipline. Each project, whether at the scale of a residence, a restaurant or a hotel is seen as a unique opportunity to explore and innovate, while fully aligning with the clients’ aspirations. 

From London to Paris, Mykonos, Cyprus and beyond, we collaborate with a discerning clientele seeking to push design boundaries and create spaces with a long lasting impact.
