The toughest and most important part of building a shed is finding the right plans. Sure you can just start building without plans, but do you know how it will look when you are done? Or you can search for free plans, but are they designed right? What I recommend is finding plans, even if it means you have to pay a little. Make sure that sample plans are provided so you know what you are getting. Do not make a purchase just because they show lots of nice sheds but no sample of the actual plans you will be buying. Look for the following before you decide to purchase:
· Saltbox sheds — they are a very attractive type of sheds which one would not mind having it anywhere in the compound. Due to its shape, it can be used to store larger amounts of items and can be used in different ways depending on their size as they come in different sizes. They are also used as children playhouses. As in the gable shed, this type of shed has two faces of roofs which meet at the center to form a peak. The only difference between the two sheds is that the saltbox sheds one of the roof sides is significantly shorter than the other.
· Wood sheds — these types of sheds are made of wood. They are the most common type of shed compared to metal and plastics. They are the most conducive as they can be used as children playhouses, outdoor office and still storage of garden tools. They are also easy to modify and renovate as increasing their size. They are preferred to other types as they blend well with the environment and give the environment a good natural look. However, they must be maintained regularly from insects as termites which feed on wood.
Remember that anything you build will either add or detract from your property's appearance and may impact your property value. Metal and vinyl materials may be easier to maintain, but are the least expensive options and tend to look cheap. Natural wood and prefinished wood products will add character and value, but are typically more expensive to buy and maintain.
Siding panels made from oriented strand board cost far less than solid wood or plywood panels, and come preprimed, saving you money and labor. Since the panels are also structural, you don’t need an additional layer of sheathing under the siding. You’ll save about $500 over the cost of cedar plywood siding. It’s the perfect material for constructing inexpensive storage sheds.

We’ve simplified the door-hanging process by mounting the door to a 1-1/2-in.-thick trim piece and then screwing the trim to the wall. An easy way to mark and cut matching hinge recesses in both the door and the trim is to clamp the trim alongside the door, making sure it extends 1/8 in. beyond the top of the door. Then mark the hinge cutout on both the door and the trim at the same time.

If you need lots of space for storage, garden room, or office space, the most common design will be the gable shed. The gable roof design has two sloped roof that resembles a little house. This design is the most popular because it blends will with your home. The gambrel shed resembles a barn. It is great for storage as no space will go to waste. A larger size gambrel shed will have enough room to build a loft. Having a loft will keep everything organized and allow you to store more stuff. By installing a ramp to the shed you can also store ATV, snowmobiles, jet skis, trailers, and such things.


Now we can actually start building!  Before you start putting down cinderblocks, lay limestone screening down in all of the channels and run and burry your electrical.  Make sure that your electrical wires are clearly marked (we used caution tape) so that nobody digs them up accidentally in the future.  Once your all set, you can start putting down some cinderblocks.  You may need to break some cinderblocks in half, and this is easily done with a chisel, a hammer, and a bit of time.  Tip:  Set Rebar posts in each corner and tie strings across to help you keep the walls straight.  You need to check every single block for level, especially on this layer as the base of the foundation will affect the rest of the foundation and in turn affect the main structure.
But I've never drilled a pilot hole in my life, so what do I know. No seriously, unless it's super delicate or thin, I just use the impact driver and make it work. Sure, sometimes the wood splits a bit, but I don't care about looks and most of my projects are built with pallets and discarded stuff anyway. But the thought of predrilling every hole?? And messing a corded driver?? Come on dude, that's laughable!
• Wastage of space — this is one of the greatest mistakes one can make. It is mostly caused by poor construction planning. You may such a mistake also by taking measurements poorly. You should consider all the activities and purposes that you will use your shed for before starting the construction. In that manner, you will be able to come up with a shed design that will suit its purpose and your wishes. One may also consider building a double floor shed to save on your compound space. You wouldn’t want to deny your kids their playing ground! You may also want to construct a different structure in the future then you get hindered due to the little space left or unless you would have to dig deeper into your pockets to modify your shed.
