The shed comes in 2 packages, and a 3rd, if you asked for the additional 3 shelves. It can be left out in the weather, it won’t hurt the pieces, but the boxes will, of course, come apart, and you will have to transport it piece by piece to where you want it installed. Best to make sure you have it placed where you want it installed. Each box weighs close to 300 lbs. They measure about 8x2x2. If you ordered extra shelves, that is a 3rd box, make sure you receive that. I have installed my shed. I had to call to have the 3 extra shelves delivered. They did not come with the first delivery. I am still waiting for them. Not sure why they offer that if they’re not going to send it.
