Design Center

In celebration of over 90 years in the Architectural Millwork business, Interstate + Lakeland Lumber has opened the doors to a state-of-the-art custom showroom built exactly where the original wood working shop began in 1922. The unique post and beam renovation blends seamlessly with the original space to provide a gallery-style setting for premium windows and doors, hardware and our specialty custom millwork

Our knowledgeable staff is on hand to answer any of your questions and to help provide solutions to any and all of your building challenges. Come sit and relax and discuss ideas away from the hustle and bustle of a job site.

“Drawing inspiration from the window display cases of Manhattan's jewelry stores, as well as artifacts displayed in New York's American Museum of Natural History, Sheldon Kahan has created a museum and gallery of his own.”
