We have a nice shed on our property and I am using it to store some pallets and plywood left over from the wedding plus my trailer and 1025R implements. My SIL also stores some of his Amazon stuff in it. But it is a long way from the house (don't know what the previous owner was thinking) and has a couple of design flaws (8' wide barn doors for example - hard to get the trailer in and out). So we are going to have Pioneer Pole Barns build one for us. We are deciding between 30x30x10 and 30x40x10 and it will depend entirely on the price difference. The desire is to be able to store the trailer, the implements, the tractor, and the Suburban and still have room left for a decent sized shop.
I'm not a fanatic DIYer like some of you guys (lack of skill), so we'll pay to have the barn built and then I will do the wiring and lighting and any other interior touches we decide on. We are in the planning stages now, so I'm thinking about leveling the area myself (good excuse for a couple more implements), and my wife is thinking about me doing the concrete floor later on. I'm not thinking about that.
I have been doing a lot of research on the subject but would welcome any ideas/suggestions/warnings that you guys might have.
