More About Our Portable Buildings


Sheds are a great way for you to create a useful and appealing storage solution. Whether, you need something small and economical like our MiniBarn, or prefer our more popular option of a Utility Shed, we have something for you. Take a look at our sheds page and see if our Utility Shed, Anaconda Shed, Mini Barn Shed, or Lofted Barn is the best fit for your needs.


Have you always wanted a getaway place but are worried about the affordability? Worry no more! Our portable cabins offer you the opportunity to have an affordable home or vacation place. Whether you want to have extra storage space by choosing our lofted cabin or want a more traditional-looking cabin by choosing our Mt. Lair or Outfitter, we are here to get you what you need!


Do you have the perfect home, except for not having a garage? We have you covered! Take a look at our prefabricated garages to fit your needs, whether you need some extra storage by having a lofted garage or a double-wide garage. However, if you are looking for a garage that more easily accommodates a smaller design, take a look at a utility garage!


A Greenhouse in Montana will allow you to grow all sorts of produce you never thought of before. Whether you want to extend your growing season or grow something that would never grow in Montana, our greenhouses are here to help you create a beautiful assortment of produce. Available with or without a floor, these greenhouses are built to last a lifetime!


Poly furniture is a great way to enjoy time by the fire or long conversations on the porch. We proudly sell Lux Craft Poly Furniture. So, no matter if you need a single chair or want to do the whole front porch, we have all the furniture you need! 

Dog Kennels

Dog kennels make an excellent place for your furry friends to enjoy the outdoors in safety. A beautiful shed makes up the box part of the kennel. While the run is made from wooden decking and chain link fencing. So, whether you need a small kennel for your pomeranian or a large kennel for your huskies, we are happy to give your furry friends the special treatment they deserve. 

Chicken Coops

Chicken Coops are a great way to give your feathered friends protection and make life easier. Offering a roosting area, nesting boxes, and shelter from the elements, these coops are a great addition to any backyard. If our coops don’t seem quite large enough for your needs, consider turning any one of our sheds into a chicken coop that can handle a large backyard flock. 

Livestock Shelters

Whether you have a small farmette or horse ranch, a livestock shelter is a great way to take great care of your animals. We offer two styles of shelters to accommodate your needs. If you are looking for a simple shelter, we would recommend our shelter with no room. If you are looking to have a little bit of extra room for your tack and tools, we highly recommend that you choose our horse barn with a tack room.
