How To Build A Shed Floor


For homeowners who are planning a shed project, starting with a solid shed floor is an absolute must. Without a sturdy floor, the shed itself will lack the overall strength and support that is necessary to be safe and long lasting.   Depending on the overall size and purpose of a proposed shed, homeowners may choose to pour a concrete slab or simply settle for a level bed of compacted stone as their floor and foundation.


While slabs are attractive and may be required for larger sheds, they represent an investment of both time and money.   Gravel and stone foundations are acceptable for small garden sheds, but they don’t offer a smooth and elevated surface to keep contents clean and dry. A wooden shed floor is generally the preferred method for backyard projects.


Construction is straight forward, there are no special tools required, and it’s a manageable DIY project.   Although there are variations in regards to actual construction, the fundamentals remain the same. Homeowners should consult their shed plans for recommendations. Before building a shed floor, a certain amount of site work needs to be performed. At a minimum the site should be level and compact.


Concrete or pressure treated foundation blocks will be used to support the shed floor at critical locations, and all of these blocks will need to be level with one another. To take site work a step further, many homeowners will start by excavating 4-6″ of earth, followed by placing a weed barrier and a layer of compacted stone, which will create a clean and professional site that will help promote drainage and will offer greater support for the foundation blocks.


A shed floor consists of a “wooden frame” that represents the footprint of the shed. This could be 10’x12′ or any other dimension your shed plans might call for. Within this frame, wooden floor joists are installed parallel to one another, generally spaced evenly at 16″ intervals. On top of this framing, plywood decking is installed to create the actual floor.


Here is a article about Shed Foundations, For buildings measuring 8′x6′ and under, a solid gravel base and a combination of foundation blocks supporting the structure is generally acceptable. Once your local building inspector has considered your shed plans, he will then determine the type of foundation that local codes require. -> SHED FOUNDATIONS <-


Plywood decking should be a minimum of 3/4″ in thickness, which provides adequate support for people, tools, and lawn equipment. As an alternative to plywood, 5/4″ deck boards may be used to create the finished floor. Once finished, you have essentially built a small deck, and the shed will be built directly on top.


While deck boards allow for drainage and will make maintenance easier, they may not be adequate for workshops, where there would be a concern for items dropping through spaces in the decking. Materials used for a shed floor should be pressure treated in order to withstand exposure to the elements.   Fasteners such as screws and nails should be treated or galvanized, and should be designed for framing and decking.


Homeowners should avoid using “drywall” screws, as they have limited shear strength. Unless specified otherwise, 2″x6″ floor joists will be sufficient for small shed projects.   Spacing between joists should never exceed 16″, as this will cause potential safety problems with excessive loads. When using plywood as a flooring material, joints should be staggered to promote strength.


This can be accomplished by starting with a half-sheet (4’x4′), followed by a full-sheet (4’x8′), and so on.   When considering how to build a shed floor, always check local building codes before beginning construction. An important rule of thumb; Always overbuild. While it may cost more, your shed will be safer and will last much longer.
