Popular Cabins Options

You'll most likely be finishing the inside of your cabin to be used as a living space. If that is the case you'll want to consider options such as insulated doors and windows to make heating and cooling your cabin more efficient. Added windows also increase the natural lighting in your cabin. If you have any questions about the options that would be good to add in your situation please give us a call. We would be happy to help you.


Loft sections come in 2 feet segments to help make more space.

The crew from Montana Structures went above and beyond with my 14×36 cabin. They made the process very easy from start to finish. With out a doubt they made dreams come true. Thank you very much!!

Extremely Pleased

The 12 X 32 Utility Shed was delivered yesterday and I’m extremely pleased with it. Titus did a great job with the delivery, levelling and positioning. The quality of the building is outstanding! Many thanks and I’m looking forward to the other two buildings.
