Your basement is the most untapped space in your home.

Whether it's a family room the kids actually want to hang out in, the entertainment space you've been sketching in your head, or a fully finished guest suite — our 5-star team takes you from concrete walls to a space you won't believe is underground.

At Cook Construction, we handle every step — design, framing, electrical, plumbing, and finishing — so you're never juggling contractors. Just one team, one vision, one result you'll love.

Wherever you are in Colorado — Arvada, Thornton, Denver, Westminster, Broomfield, Boulder, or Brighton — experience construction as it should be.

  • Every guy deserves a space that's 100% his. Big screen, surround sound, cold drinks on tap — and nobody asking to change the channel. Whether it's game day headquarters, a poker room, or just the place you disappear to after a long week, we build man caves that your buddies will never want to leave.

    Custom built-ins. Sound-ready wiring. Bar-ready plumbing. We think of everything so you just have to show up.

  • Movie nights. Homework stations. A play area that isn't your living room. The best family basements aren't just extra square footage — they're where your family actually lives. We design spaces that grow with your kids, give everyone room to breathe, and keep the upstairs looking like adults live there.

    Durable finishes. Smart layouts. Built for real life, not a magazine cover.

  • When family moves in, everyone deserves their dignity. A private entrance, a full bathroom, a kitchenette — we build suites that feel like their own apartment, not a spare bedroom with a microwave. Your parents stay close. Your household stays sane.

    ADA-friendly options available. Separate climate control. Designed for comfort and independence.
