Born from a belief that exceptional interiors deserve exceptional execution, Studio TSL is an interior design practice that creates considered spaces where beauty, functionality and craftsmanship exist in perfect balance. Established by Creative Director Johanna van der Merwe, the studio draws on more than 17 years of experience across luxury residential, hospitality and commercial projects to transform ideas into environments that are as effortless to experience as they are to deliver.

As part of the wider TSL Group, alongside The Sourcing Lab and TSL Projects, Studio TSL approaches every project with an uncommon understanding of the complete design journey. From the earliest concept and material selections through to procurement, technical detailing and final installation, our work is guided by the belief that great design is not only imagined beautifully, but realised beautifully too.

Every space we create begins with the people who will inhabit it. We believe thoughtful interiors should reflect individuality, evoke emotion and improve the way we live, work and connect. By combining timeless design principles with an exceptional understanding of materials, craftsmanship and execution, we create spaces that feel intuitive, enduring and unmistakably personal. Our expertise lies in balancing creativity with precision, ensuring every detail serves a purpose and every finished space feels exactly as it was intended.
