Preparation is the most important step when building a shed. If all the appropriate groundwork is completed, you can save time and money in the long run by not making costly mistakes.
First, research and select a plan. There are many available online. BuildEasy has a free plan for an eight by ten foot shed. When you browse through the choices, make sure to take into account what you want to store. If you have a 54 inch riding mower, your shed door needs to be wider than the typical 48 inches. Also make sure the plan allows for air circulation. Vents or windows allow the hot or cold air to escape and for proper ventilation should you do any projects in the shed.
Check with the local restrictions of your area. Most cities or communities require a permit to be on file for any dwelling built on residential premises. This will ensure the plan meets all neighborhood codes for safety.
Pick a good spot for the shed. A good foundation should be on firm ground with good drainage. Ground that puddles after the rain can rot the shed floor prematurely.
Purchase and pick up, or order and have delivered, all of the necessary materials. Check the list twice before starting. Having to run to the hardware store in the middle of a project can be time consuming and frustrating.
When assembling your floor, be sure to follow codes for anchoring it into the ground. Using weather resistant, pressure treated lumber is also a good idea as the bottom will almost always be exposed to the elements.
When building the walls, use low maintenance materials. You most likely won't have time to work on the shed often, so putting a little extra time and/or money into it now, will let you use the time to do the lawn work instead of shed repair.
The roof will be assembled using trusses or a ridge beam with joints. Read through your directions to see which type you are using. Also, make sure to use hurricane straps for the most secure attachment to the walls. Researching different shingles and roof types (for example aluminum) and their costs can help you make the best decision for your needs and budget.
Finish the shed with a higher-grade caulk containing silicon. Anywhere water could seep (around door, windows, and where the floor meets the walls) should be caulked. Finally, a coat of exterior paint that compliments your house color should be used to conclude your hard work.
Whenever you use tools or small equipment, be sure to follow all safety procedures. Wear protective eye wear and gloves, follow manufacturer's directions and use common sense. Have a telephone nearby for emergencies, and if possible, have someone else around that can help you if you need it.
