Don’t assume that you’re missing something if you have a question that cannot be answered within the guidelines of the shed plans. Builders at all levels will always have questions and it is better to ask the question than miss something important in the process. Go online and find a forum or a video if you have a question. Better yet, read all the little print that you skipped over in your shed plan and see if the answer is there, it might be.
For the masonry of the foundation we went out and bought 15 cinderblocks, and suplemented these with clay bricks that we got for free off of kijiji and some concrete pavestones from a neighbor's old patio. Clay bricks can only be used above ground, other wise they will erode. Looking back, it would have been easier to simply use cinderblocks and we strongly recommend it if you don't have other materials to get rid of. Also, buy more mortar than you think you will need. We ended up using a lot of mortar and if you have any extra you can always return it or pour it in the cinderblocks like we did to make the foundation even stronger.
I would advise you to aim for the type of wood that is resistant to deforming, fading, pets and dampness. Once at a local lumberyard, request for the heartwood, which is the innermost part of the wood in a tree. Unlike sapwood which is the outer most wood found in a tree, it is resistant to harsh conditions. The following species of wood are suitable for shed building: Cedar, Cyprus, and Redwood. Before buying the wood, check thoroughly that it has been well processed. Be cautious of wet wood to avoid shrinkage after you have already bought it and also Greenwood which may cause you inconveniences. The most common type of outdoor wood is pressure treated and consists of pine and fir.
There are a number of considerations when it comes to choosing an outdoor storage shed for your home. There’s the question of price, design, climate, size, and more. To begin with, realize that you get what you pay for with a storage shed. Saving a few hundred bucks on the cheapest model might not make the most sense in the long-term. This means that you’re passing on quality siding materials like cedar and vinyl. Next, think about how you want the shed to look in your yard. We’ve all seen those classic storage sheds that are designed to have the same aesthetics of your home. For instance, rustic designs for a country-style home. These complementing designs can be quite charming, and allows the shed to stand out as an addition of your home. Another option is to have your shed bleed into the landscape by covering it with plants or by planting perennial beds around the unit.
I don't waste my time on free plans, store-bought sheds, or ready-made, mail order kit solutions... been there, done that. Free means lack of user feedback and you get absolutely no customer support. With store-bought and ready-made mail order sheds: they're flimsy, profit-driven solutions that I've always had to tear apart and modify too much to get the storage space to work or to match the character and style of the home.
When you’ve decided on a shed location, dig two trenches 16 in. wide, 12 in. deep and 13 ft. long. Center the trenches 66 in. apart. Fill the trenches with a 3-in. layer of gravel and compact it with a hand tamper. Repeat this process until the trench is full. Use a level and long board to level the top layer of gravel. If the ground is flat, also make sure the gravel beds in the two trenches are level with each other.
