Loon Lake Co. is a residential design studio focused on custom homes that belong where they’re built.
Every project starts with listening — to the land, to the needs of your family, and to the way you want your home to feel and function. We work collaboratively from concept through permitting, ensuring every line on the page serves a purpose. Whether you’re working with a builder or just beginning your vision, Loon Lake Co. offers a streamlined, high-touch process from first sketch to final set
Gerrit Szeszycki, M.Eng.
Founder/Architectural Director
Over the last 10+ years, I’ve helped bring dozens of homes to life across Michigan, Illinois, Florida, and beyond. Before founding Loon Lake Co., I was the lead designer for a high-end custom home builder, where I created hundreds of full plan sets from the ground up.
With over 20 years of experience working in Revit and AutoCAD, I bring deep technical fluency to every project — from concept modeling to permit-ready construction drawings.
Now, through Loon Lake Co., I offer that same precision, design clarity, and site-specific approach directly to homeowners and builders who value thoughtful residential design.

Chief Nap Officer
When he’s not curled up under the desk or keeping an eye on the neighborhood from the office window, Oslo ensures every plan passes the vibe check.
While not formally trained in residential design, he excels at sitting quietly through zoning reviews and offering strong opinions on lunch breaks. He’s been part of the team since day one.
