Commercial Design-Build Contractor Work

At KOZI, we’re proud to be one of Pennsylvania’s most reliable commercial design-build contractors, offering efficient, end-to-end solutions for businesses throughout the state. By overseeing every phase of your project in-house, we help you save time, reduce costs, and minimize stress—so you can stay focused on your business while we take care of the construction.


KOZI has years of experience providing design-build services to businesses in the Lehigh Valley, including Allentown, Easton, Bethlehem, and nearby counties. Unlike the conventional construction model that involves separate contracts with architects, engineers, and builders, our integrated approach ensures consistency, accountability, and high-quality results from start to finish. Contact us today!

  • Durable Craftsmanship designed to stand the test of time
  • Responsive Service throughout every phase

"We are extremely happy with the results of our remodel. Kozi stayed with us through any changes and made sure we were happy with every aspect of the final product. We removed an old addition and deck, increased the size of the previous addition and rebuilt the deck. Kozi did a beautiful job with all of it. Thanks!"
