The Koli Interior Door 

Introducing the first customizable modern interior door system. 

Intelligently designed to bring a modern design element to any room in the house, the Koli interior door brings a proper balance of clean lines and alignment, while simultaneously leaving some room for creativity and a personal touch.  

Like statement jewelry, but for the house.

The Koli modern door serves two purposes: it’s basic function as a room divider and a second one, providing a decorative and furnishing element to a room that communicates a personality and starts conversations.

The piece that allows for the most creative configurations in the Green Oxen collection of products, the Koli interior door comes with unlimited infill options. From frosted white glass for a modern bathroom, to printing your child’s artwork for a colorful playroom, the door is highly customizable, easy-to-install and low maintenance.

The Koli interior door is made of 100% ethically recycled aluminum, adding value to your property and defining sustainable luxury living.

The Koli interior door is a door that makes a difference.

When conceptualizing the Koli Modern Door, Green Oxen designers wanted to engineer an entire interior door system so that everything works together and nothing is needed from a 3rd party. The Koli Modern Door kit will include concealed hinges for when opening up to 135° and multi-link hinges are available for 180° opening. The mortise lock comes standard and you will have the option to purchase the leaf with or without the infill panel. See the configurator (only on desktop) for all lock and hinge options.

The Koli Modern Door System comes with a rubber seal to be installed around the system’s perimeter. The door’s casing can be combined with the revealed Vinson aluminum baseboard to create a seamless modern wall design. Allowable wall thickness range from 3-31/32” to 5-1/32”. The Koli Door System installs after wall and floor finishing. Double doors are also available. If there are special requirements for your project, let Green Oxen know and we’ll make sure you’re satisfied with your custom door order. Download a brochure.

The real fun with the Koli Modern Door System is when choosing the infill for your door. There is a multitude of infill panel options that are stock offered by Green Oxen and infinite options for a requested or custom infill. The popular infills are glass, wood, laminate, prints on acrylic. See more here.

It is the early stages of the Koli Modern Door operation, but soon customers will have the option of uploading a photo to be printed on glass or even aluminum. The resolution will be up to 450 dpi, but only high resolution photographs should be considered. Even further down the line, Green Oxen will consider allowing customers to provide their own infill.

The Koli Modern Door’s top benefit is in its sophisticated, unique look, but beyond aesthetics, the door has functional benefits. First is in how easy it is to install. The self-supporting aluminum door jamb requires no shimming.

The sleek, extra clean look is not only due to the frame and infills, but also the lever & lock that has no escutcheons.

The Koli Modern Door may also be the most sustainable metal door created. It is the perfect door for high air quality requirements, no VOC’s are used in production. The Koli is easy to clean and maintain and it is a premier product from Green Oxen. As always, recycled aluminum is in the content and it is formed using machines powered by wind energy. The perfect addition to any LEED project.

Green Oxen is committed to sustainability. We use wind energy to power the machines in our facility. All of our products are made with recycled aluminum.


We specialize in a vast selection of doors including: Rustic, Eclectic, Pocket, Barn, Kids and Printed Doors.
