Many people would not even consider this as a tool, but this the single most important aspect to ensure that you will have a great flow when building your shed. With your plans, you can determine the exact number of materials that you will need what type of materials and all the other tools that will be required. This is the first step always in building any structure. There are many different types of foundation that one can choose from. Depending on the size of your shed and what you plan to store inside, you can choose from either a concrete foundation or just the plain earth. The latter is not really recommendable especially if it contains a lot of moisture. To further prevent moisture from seeping into your firewood, you should put a layer of plastic on the floor and to allow good airflow for drying, under your woodpile stack your firewood on off-cut lumbers. Most firewood shed are not really that big, they are easy to make and don t require as much cost as most typical storage sheds. Without it, you might as well be walking blind, groping as you go along with your pallet shed project. Wood is not the only material you will need. So you need to prepare all the other materials and your tools as well. If you don t have some of the tools needed, you don t have to go out and buy them, just borrow them from your friends, but be sure to return them though. You can use this for trimmings and maybe even for shelves and window sidings. Drive around your town, renovations and demolitions are a good source for reclaimed materials. They can either be used as land fillers for foundation or for roofing materials. You can even go to your local junkyard and ask if they have aluminum or metal which you can get for free or buy at a minimal price. This part of your shed is very crucial. They should be able to protect the contents of your sheds and also be able to withstand harsh weather. Your plans should be very detailed as to the rafters and beams and also the type of roofing material. You can now just put your finishing touches such as trimming the shed and painting it as well.
