Is it odd that this older kit is currently out selling all others? It is very flexible, but is there something about it that folks find particularily attractive ?
There are several other steel-sided kits that I think are complimentary to it.
The two steel utility sheds with and without windows are obvious as is the large steel mill building.
Or, the American Steel Pipe mill flat, the Tin Shed or even the Steel Car Barn. Personally, I like to work in some brick with my steel, like the Small Factory, the Turbine House & Plant #2.
Guess they all look good together.
If your one of the many people who have the small steel mill building, it would be great if you shared your thoughts on why you bought it and how your using it.
