There are two great pains to building. First, getting rid of all the rubbish. Second, where to put all the materials you get delivered. Especially since sometimes they'll happen at the same time!
Mini-skips are a massive saving of time, planning and frustration, so we'd definitely recommend hiring one. But delivery... Sometimes more tricky. You are going to need a place to put all the lumber that is going to be dropped on your doorstep. The ideal place to put materials is your garage. There they will be relatively safe from the elements and any possible predators, like opportunistic and strong wood thieves.
If you're like me, your garage space might already be fully allocated. There's the used Harley, a new radial arm saw, a pickup truck and seven bicycles in various states of disrepair. To procure adequate space for beams, plywood and 2X4s could amount to a mammoth undertaking.
There is, however, one spot in the garage that always stays neat and clean and is large enough to house enough wood to build an addition. It is the parking spot for your wife's Oldsmobile.
Modern delivery trucks are usually a huge flatbed with a forklift hooked on the back. The delivery person can save you a lot of work situating your lumber if you have him place it where you want it at the time of delivery. If you're going to use it quickly, then putting it where you're going to use it can be useful. The forklift can maneuver your load into some tight places. If you take up your wife's parking spot, the forklift should have no trouble at all.
The real trouble starts when your wife comes home from that little shopping expedition you sent her on to get her out of the way while the anticipated lumber is being off-loaded. Hopefully, she will return AFTER the unloading has been completed. "What's all of this stuff doing in my parking spot!?"
Your wife is not likely to believe that the delivery was made while you were inside cleaning the house and that you didn't see where the delivery man put it. It is best to be prepared with an answer that at least has an air of practicality and inevitable necessity. "I thought I could put it all on my side of the garage, but that huge glue-laminated beam would only fit on your side."
When she nods her head skeptically and asks, "Where is your tape measure?" that's when you know that your plan for lumber storage will probably need to be revised. Twenty minutes of following her around with a tape measure will make it clear that it will be your pickup that ends up in the driveway or on the street. You're going to have to find a way to hang the bicycles from the ceiling, AND you will be required to move a ton of lumber by hand because your wife prefers her spot to any other space you clear out. (Her parking spot is close to the door, and she does not want to climb over a wall of shaved timbers to get into the house.)
