The wood of course is your most single important material. You also need tools like hammer, saw, nails, hinges, roof tacks and shingles. Based on your plans, measure your wood and cut them to size. If you re using a concrete foundation, prepare your cement. With any structure, you always build starting from the bottom. 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. Whether you decide to buy or build one this is by far your best option. If you do decide to build it yourself, then kudos to you, building a garden shed is one of the simplest task in rudimentary carpentry. If you have a great command using tools and have a free weekend or two to work on some measuring, hammering, cutting, drilling and sawing, then all you need are the proper materials, tools, building plans, and you can soon have your very own shed in your own garden made by your own two hands. But for other parts of the shed, you wouldn t need steel that are as strong, for example, for the structure or frame, you will need stronger steel, especially the rafters for roof support, but for the walls and the roof itself, sheet metal would suffice, or even corrugated steel sheets. Aside from the reputation steel has of good strength, steel is also highly desired as a building material because it requires minimal maintenance and there is virtually no infestation of bugs like termites or even carpenter bees. Depending on your choice as roof material, you can now finish your roof placing your chosen material as per manufacturer s instructions. Safety is always the key, as you would be working on the roof, there is a chance that you may fall off. If possible, get someone to work with you and make sure that when using ladders or other tools for elevation that it is secure. The ever growing need that we all have for space have led to this construction boom and it has become unavoidable for every property to have one. Many have languished in the fact that many of their tools and belongings, which are not suited to be stored inside the home, have dominated their garage and that their garage has lost its main function, to park their cars safely.
