So, if two or more persons are building the shed, you can simultenously build the foundation and the shed itself. Also in some states if a structure is not permanent, you won t need to apply for a permit, eliminating the fees involved and the time spent in waiting for your permit. There are some disadvantages though when using a skids foundation. You may think that having a fairly good slope and enough driving space would be enough, that isn t the case. Many of these machines have an undercarriage and can just as easily ground over the threshold of the door. Six inches of space under both sides of your door opening will allow you to have an easier time to take your machinery in and out. You can do this by using by using storage shed kits and pre-fabricated storage shed parts. Many home specialization stores today carry these kits. There are also different choices in materials when building a storage shed, whether doing it from scratch, or by using kits. The most common are wood, steel, and vinyl. A good set of plans, whether you downloaded it for free, bought it, or created it yourself should have a complete and detailed list of all the materials you will need, including their exact measurements. The options you would want to do, have a step by step guideline, a drawing of the structure, preferably 3D, and illustration along with the step by step instructions. Second, check with your local planning and zoning commission and show them your building plans. This way, you can be assured that you will have no problems with the authorities later on. Now let s start building. It is imperative that you have all your materials prepared before the actual building process. 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.
