Our work


Since our inception in 2001, 186 has designed lighting and control systems for exclusive residences in every region of North America. Our work can regularly be seen in local and national magazines including Architectural Digest, Dwell, Timber Frame Homes, Luxury Living, Luxe, Architecture and Design of the West, Ski Magazine and Aspen Magazine to name a few. 186's projects have also been seen on CNBC and HGTV.

Our philosophy

At 186, we work as an integral piece of every design team and strive to create an atmosphere of cooperation with all construction trades during each project. Our simple design philosophy is to adapt our style to each individual project rather than apply our style to every project.

Our vision

In the interest of making the world a better place, 186 has a renewed interest in creating energy efficient lighting designs. As lighting technologies rapidly evolve, we are in the position to continuously adapt our design process to increase energy efficiency without sacrificing beauty or performance. Learn more...
