I have about 6 menards buildings in O gauge (power plant not being one of them).
I recently looked at the HO buildings, and contemplated how they would scale up for S, and ultimately, to my eye they were to small. It seems to me, that an industrial building is generally proportioned bigger than the train, not smaller, especially when a train is going through it, or next to it. The only O buildings that look blatantly out of size to me in an S world are residential buildings. Menards O gauge factories, plants, engine facilities and barn all work in my mind because there is no set or standard size common to all structures of that nature, generally no two barns are a set size in hight, with and length. This leaves open the ability for a lot of plausibility with incorporating smaller O gauge structures into the S world. The only real issue for me is the doors. Windows on industrial and commercial facilities and be huge, and bay doors are of all sizes, but people doors....not so much. I don't much care for how the actual numbers work out to be S scale (L*W*H) but that to my eye the train and building seem proportional (more or less).
A Menards example at the top, barn meant for O gauge, but to my eye works well with S.
