rooted in love

Founded by husband-and-wife team Scott Heuvelhorst and Katerina Kouzoukas, SK Design Group brings together diverse perspectives to create a refined and cohesive design vision.

Scott is a self-trained interior designer of Dutch heritage with deep expertise in curating custom spaces. Katerina, a Chicago native of Greek heritage, is an interior architect recognized for her worldly, sophisticated aesthetic. Scott’s technical knowledge and thoughtful approach pair naturally with Katerina’s bold creativity and intuitive design sensibility.

Influenced by their international travels, the team approaches each project with a cultivated sense of place and detail. The result is carefully layered interiors that feel elevated and distinctly personal.
