Spur of the moment decision. My son-n-law and I bought a pre-built wood frame metal walled and roofed building. Was built on site by seller unfinished on inside. Once shell was built, my son-n-law and I did all the inside work: framing, plumbing, electrical and finishing. All the inside done in traditional rustic cabin style. Looks sort of plain on the outside but absolutely beautiful and unique on the inside. We built this cabin because when guest came to visit, our house was full and there was no place for guest to sleep. Has worked extremely well. Also is stand by "dog house" if wife kicks us out for a spell!
