Put up a 40 x 60 x 10 with 5 inches of concrete 4 years ago. Mine is made of wood (shingles). That was almost 5 years ago and I know I have at least $50,000 in it. The inside walls are insulated and the inside is finished (walls and ceiling). If my health is ok I plan on getting the ceiling insulated with blown in insualtion next fall.


They are never big enough but I can keep my boat under a roof. With the insulation I never did see the temperature get below 30 this winter with just the sidewalls insulated. I really find that a little odd but I am satisfied with it.


With the insulation and finished walls and ceiling i probably have close to $60,000 in it.

Had the tresses built at an angle where a person can stand in the loft....lots of room for storage.
