Prebuilt portable garage shed?
We have two of them. The one on the left is a 10 x 36 and stores both the GTS and the 28 Model A hot rod. The one on the right, 12 x 24, stores everything else, lawn tractor, snowblower, all the year furniture, motorcycles etc.
Nothing in the main garage except project work at the time. The right side shed is about 20 years old at this point in time, needs some new shingles but the floor is great.
