Hello! I’m Geoffrey Smits, the founder of SIEdes (Smits Interior Exterior Design Studio).
I grew up in a boating family and spent a lot of time on the water from a young age. In addition to organizing sailing competitions and coaching young sailors, I have also competed in many regattas – both in smaller boats and in long-distance offshore races.

This hands-on experience deepened my appreciation for the maritime world and led me to study Naval Architecture and Maritime Technology at INHOLLAND University of Applied Sciences, where I earned my Bachelor of Engineering in 2009. Alongside yacht design, I’ve always been interested in design—everything from cars to architecture. These different influences help me bring together technical and aesthetic elements in every design.

After my studies, I began my career in yacht building, working as a designer/engineer at Victoire and Studio Delta. I then transitioned to commercial shipbuilding at Damen Shipyards, where I worked as an all-round engineer on tugboats and workboats. My expertise further expanded at Huisman Equipment B.V., where I served as a Naval Architect and CAD Coordinator, contributing to conceptual designs and studies for offshore vessels.

In 2016, I moved to C-Job Naval Architects, where I worked as Lead Naval Architect and Concept Designer, helping to establish and manage the Rotterdam branch. In 2023, while still serving as Head of C-Job Studio, I decided to follow my own path and founded SIEdes to further realize my vision for interior and exterior designs in yacht building and the real estate market.

SIEdes combines 3D modeling and photorealistic renders with practical, tailor-made design solutions. Whether it’s new yacht designs, the renovation of existing vessels, or commercial projects, I leverage my experience and expertise to ensure every project is a success.
