ABOUT

Lukas Kos creates quietly powerful spaces that enrich daily life—residences and hospitality interiors shaped by bold conceptual clarity and disciplined delivery. Working across Canada and the U.S., he brings an international body of work and a process that is clear, structured, and dependable from first sketch through construction.

In practice since 2012 (and in the profession since 2006), Lukas has led projects across high-end residential and hospitality in North America, Europe, and Asia. His work has been recognized by leading publishers and awards, including a Best of Year honour from Interior Design magazine for Cloud Villa in Shanghai, alongside recognition from the Restaurant & Bar Design Awards (London) and the A&D Trophy Awards (Hong Kong). Select projects have also been featured in major design publications and cultural campaigns.

Before founding his studio, Lukas worked in Los Angeles, Toronto, and Shanghai, including time at Frank Gehry Partners, contributing to hospitality, cultural, and luxury retail projects. Today, he leads each project with a small senior team, including a dedicated Director of Interior Design, bringing clients a steady decision-making rhythm, strong coordination, and a finished result that feels precise, lived-in, and enduring.
