One option is to get a plan online, while there are free plans available, most of them are not complete, so there s really no point in getting any of them as it may even cause you more problems. What if the plan you got did not have any guidelines in laying the foundation? Without a complete detailed list of the materials needed, you may end up buying, more than what s needed. In building a wooden skid foundation, you first need to select a spot then prepare a bed of gravel which will be able to provide a flat level and stable surface to allow water to drain beneath it and keep your lumber dry. Atop this gravel you will set wood beams or timber. These beams and timber will act as the skids. The location of your firewood shed is one of the most important decision you should make It should be in an area where water does not pool around the shed, yet it should be near your home so that it would be easy for you to get firewood whenever you need it. You certainly wouldn t want to walk far just to get some when it s raining hard or there is heavy snowfall. You have to make sure though that your roof is weather tested and is capable of enduring heavy weather conditions. Even if you already have a barn, a loafing shed is still a good investment as this can be placed in the pasture where your horses graze. Or this can also be a place where you can put horses ready to give birth to keep them away from the herd and from potential danger. You should also choose only quality shed roofing materials to ensure that they will be able to guarantee you that they will be able to withstand any harsh weather, plus many of these quality materials have warranties, like the 20 year shingles. With any structure, the roof is the most critical part, it should be able to withstand a heavy load, protect against the sun, rain and winds, and equally important, look good as well. Don t be afraid to get your hands dirty, even with minimal carpentry skills, you too can build a strong, sturdy and aesthetically pleasing shed in your garden. Scour for materials that can be recycled. Old wooden crates can still be used for flooring and for walls. Fallen trees can be cut and used for rafters and as foundation, maybe even a door.
