William Vandenburgh brings a unique blend of technical expertise and creative problem-solving to SDK Architecture. With a Bachelor of Science in Finance from Case Western Reserve University and a Master of Architecture from Pratt Institute—where he was awarded the prestigious Alpha Rho Chi Bronze Medal—he seamlessly bridges the gap between artistic vision and structural precision.

His passion for architecture was ignited at an early age, growing up on construction sites alongside his interior designer mother. Later, Will refined his hands-on skills combining a passion for growth and philanthropy working with Habitat for Humanity.  Will thrives on the challenge of transforming abstract concepts into tangible, lasting spaces, balancing creativity with meticulous attention to detail.

Dedicated to crafting environments that feel both functional and personal, he finds fulfillment in helping clients build their own unique worlds. Outside of architecture, Will is an avid outdoorsman who enjoys hiking, backpacking, and woodworking. Whether experimenting with 3D printing, strategizing over a chessboard, or cooking for friends, he is always drawn to the process of making—both in design and in life.
