About Us

Over 25 Years of Construction Experience

We specialize in designing custom cabinetry, shelving, and closets for people like you—people who want to get the most out of their space! We’re located here in Sioux City and perform custom millwork that we tailor to your surroundings, with special consideration given to efficiency and organization at home and in the workplace.

We service all of our work to give you, “Peace of Mind”… as we say Satisfaction Guaranteed! The owner or project manager assures you that your project will get done on time, and receive all the attention you expect.

This way, we’re able to create an environment that mirrors your daily routine, resulting in a more effortless and enjoyable day-to-day.

Here at 3K LLC, that’s the aim—custom tailored design that simplifies life.
