Keens did a nice job in installing a workshop on our family farm in South Georgia. In spite of delays with Covid they were able to get it delivered and installed with no major problems. The staff is very helpful to their customers


I cannot emphasize how happy I am with the finished product…I started working with Josh at Live Oak back in March and after numerous trips and emails, I settled on a size of a custom bldg in April. It took several months to get my pad poured but we had a very wet summer. After multiple color changes and layout mods, we locked in after the pad was poured and our building was erected in about 1.5 days by probably the best crew TBS out of Lake City has. very professional crew and no detail in installation was left out…If you are in the market for a custom built building, I would not hesitate to give them a shot. I had a previous building done by a different company that really got botched..The Sales and your concrete guy really and installation crew is what makes this. And Keen’s recommendation on who to use for concrete was also top notch…


Beautiful Work!

We purchased a shed about 6 months ago and we love it! Keen’s was professional, helpful and personable! They installed our shed in a timely manner and I highly recommend using Keen’s!

Great place. DJ came to my home twice to check the size carport that would fit on my slab. Mike was helpful in assisting me with the process of acquiring a permit. I was going to go with someone else who sold Carolina carports but when I found out that Keen’s deals with a local company, Tubular Building Systems in Lake City Florida, I made my choice. I would rather deal with a local manufacture. Thanks again.

Great place to shop a storage shed building. There storage sheds and buildings are superior quality and they offer the best building – frame wood or steel, loads of door and window options, wall and roof finish options all at the highest FL wind code. Steel Carports, RV and Boat covers, large steel garage buildings, and other custom steel buildings and more are offered as well. Gazebos, Two story buildings, Dog Kennel/Houses and more quality and long lasting products as well. Nothing is more satisfying than owning the best quality products for a fair price that last!
