Put up that exact 10X14 Arrow shed a little over a year ago. Picked it up at my local Lowes on clearence for $200. My original plan was to build a wood frame similar to a poll bar and use the metal from the kit to side it and do a regular roof, but ran out of time and needed something quick for some overflow storage. I like to refer to it as the erector set from hell. Took about 2 weekends to put it all up working by myself with a helper it could easily be done in a weekend. That also included leveling 3 yards of crushed stone and building a wood floor/platform. All was good and it survived our winter 2 years ago when we had over 6 feet of snow but i did clear the snow off twice by the end of the winter the snow was up to the roof of the shed. A limb fell on one corner during tropical storm Irene and another during a wind storm at least they both hit almost the same spot. Some time with a block of wood and a hammer got it looking ok again. It does leak a little but for what i keep in there its no big deal. Would i do it again only if i really had to this will be replced with a wood shed of about the same size when this one rots out or with the way its goinf gets hit my another tree.
Here is a quick right up i did for another site im on with some pictures.
Someone shoot me 5,000 or so misc screws nuts and bolts 200+ hand pulled rivits and 20 or so man hrs and its almost done just the doors and a few other odds and ends. I should have just stick built it would have been done in a fraction of the time.
