Founded in 2018, DCSK is a London-based practice that is dedicated to designing buildings and spaces for the 21st Century city.

Directors Fernando Da Col, Paul Sutliff, and James Khamsi come from different countries, and have diverse track records working in cities all over the world, across a range of scales, for private and public clients. This makes us nimble, adaptable, and able understand different contexts and challenges quickly.

We bring experience in architecture and urbanism, and share a passion for making equitable and sustainable cities. Our strength is that we understand the inner life and needs of buildings, but also how buildings and spaces come together holistically to make a city.
