The Cumberland log cabin comes in four sizes: 392, 448, 504 and 560 square feet. I am going to give you the prices for the 392 square feet one. The insulated kit unassembled costs $16,348. The pre-built insulated basic shell costs $18,164, while the pre-built deluxe finished costs $29,924. This kit is very unique; it has two reverse gables and a centre porch. Two lofts are located at each end thanks to its great design. This log cabin kit is the perfect choice for those people that want separate lofts.
