The Complete Handyman's Guide to Constructing Your Own Shed
Intro
Building your own shed is a fulfilling project that allows you to create a functional, customizable backyard structure. With proper planning, preparation, and step-by-step execution, you can build a high-quality shed tailored to your needs from the ground up.
This guide will walk you through the end-to-end process of constructing a shed, from developing the initial plans to putting on the finishing touches. We'll cover key steps like laying the foundation, erecting the walls, installing roofing and siding, adding doors and windows, and completing the interior and exterior detailing. With the right materials, tools, and techniques, you can have a fully-functioning shed that makes an attractive and useful addition to your outdoor space.
Building a shed requires patience and attention to detail, but the sense of accomplishment and upgrade to your property make it a rewarding DIY project. Follow the steps outlined here and you'll have the knowledge and confidence needed to build a shed from start to completion.
Planning & Design
The first step in building a shed is planning and design. This involves deciding on the size, style, and purpose of the shed.
Size
Consider how much space you need for storage or activities. A larger shed (10' x 12' or bigger) offers more room but requires more materials and work. A smaller shed (6' x 8') may meet basic needs while requiring less effort. Think about your long-term goals too so the shed doesn't quickly become too small.
Style
There are many shed styles to choose from:
- Lean-to sheds attach to another structure like a house or garage. They're easy to build and access.
- Gambrel sheds have a barn-like roofline that offers more storage space. The steep sloped roof helps shed rain and snow.
- Saltbox sheds have a simple angled roofline but provide a lot of headroom.
- Cottage sheds have a front porch and look like a tiny house. They're charming but require more detailing.
Consider factors like roof pitch, windows, and architectural details that match your home.
Purpose
How will you use the shed? For garden tool storage, a workshop, storage for larger outdoor items, or a combination? If using it as a workshop, think about lighting, electrical outlets, ventilation, and workbenches. For storage, maximize shelving and floor space. Knowing the purpose will inform other design decisions.
Take the time to carefully plan and design your shed. This will save you time, money, and frustration down the road.
Permits & Zoning
Determining if you need a permit to build a shed depends on your local zoning laws and the size of the shed. In most cases, you will need a building permit if:
- The shed's floor area exceeds 100-200 square feet. This varies by municipality, so check with your local building department.
- The shed is a permanent structure with a foundation. Temporary sheds may not require a permit.
- The shed has electricity. Electrical work usually requires permits.
- The shed is over a certain height. Often sheds over 8-12 feet tall require permits.
- You live in an area with homeowners association rules or strict zoning laws. Some neighborhoods prohibit sheds or limit their size and placement.
Even if permits aren't legally required, it's a good idea to check with your local building department. They can inform you about zoning regulations like required property line setbacks. It's better to find out ahead of time than to build a shed and be forced to move or alter it later.
Getting the proper permits also protects you down the road when selling the property. Unpermitted work can jeopardize future sales. Building code officials can ensure your shed is structurally sound and safe when built properly to code standards.
Site Preparation
Proper site preparation is a crucial first step when learning how to build a shed. Taking the time to level the ground and address drainage will create a solid foundation for your shed build.
Level the ground: Identify the exact spot where you want your shed to sit. Use a shovel, rake, and leveling tools to remove high spots and fill in low spots. Compact the soil with a hand tamp or roller. You want the ground to be as level as possible before building.
Consider drainage: Make sure water will properly drain away from the shed's foundation. Direct downspouts and gutters away from the shed. Install gravel, crushed stone, or patio blocks to encourage drainage under and around the foundation. If the ground is soggy, consider adding a drain pipe or trench filled with rocks.
Proper site prep takes effort upfront, but prevents major problems down the road. A level site with good drainage will keep your shed stable and dry for years to come. Don't cut corners here - take the time to prep the site right before moving onto the fun parts like framing and roofing.
Foundation
The foundation is a crucial part of any shed build. It provides stability and ensures the shed will last for years to come. There are two main options for shed foundations: a concrete slab or a wood frame foundation.
Concrete Slab
A concrete slab provides a solid, permanent base for your shed. To build a slab:
- Excavate the area, removing any topsoil or vegetation. Dig down about 6-8 inches.
- Fill the excavated area with a 4-inch layer of gravel and compact it down. This will provide drainage under the slab.
- Build the formwork - set up lumber frames around the perimeter to hold the concrete pour.
- Add reinforcement such as rebar or wire mesh before pouring concrete. This strengthens the slab.
- Pour a 4-6 inch thick layer of concrete into the formwork and allow to fully cure, about 5-7 days.
A concrete slab is the most durable foundation option. However, it requires more labor and materials than a wood frame.
Wood Frame
A wood frame foundation is simpler to build than a slab. To make one:
- Lay out a frame using pressure-treated lumber. Use posts or piers under heavy load points.
- Attach the frame securely to the posts with galvanized hardware.
- Enclose the frame with plywood skirting around the perimeter.
- Compact gravel under the frame for drainage.
A wood foundation is usually less expensive than a slab, but it won't last as long. Regular maintenance may be needed as the wood ages.
Choose between a concrete slab or wood frame based on your budget, timeline, and needs. Both can provide a solid foundation for a durable backyard shed. Proper site preparation is key for either option.
Framing
The framing of your shed is one of the most important parts of the build. A sturdy frame will ensure your shed lasts for years to come. There are three main framing components: the floor, walls, and roof.
Floor
- Use pressure-treated lumber for the floor joists. These resist rotting and insect damage.
- Space the joists 16-24 inches apart depending on the size of your shed. Consult building codes for exact specifications.
- Lay the joists across support beams on a concrete slab or foundation. Make sure joists are level.
- Add plywood or OSB sheathing atop the joists. This provides the floor's surface.
- Secure it with screws or decking nails. Be sure to leave a 1/8 inch gap between sheets to allow for expansion.
Walls
- Build each wall flat on the ground, then tilt up into place. This is easier than framing vertically.
- Use 2x4 studs spaced 16 inches apart for wall framing. This meets structural requirements.
- Nail a top and bottom plate to the ends of the studs for stability.
- Add diagonal bracing across the wall studs to prevent buckling.
- Install door and window headers where needed for structural support.
- Sheath the walls with plywood or OSB, leaving a 1/8 inch gap between sheets.
Roof
- Use 2x6 or 2x8 rafters spaced 16-24 inches apart. The size depends on your roof's span.
- Install collar ties between rafters for lateral stability.
- Add blocking between rafters to provide attachment points.
- Install roof sheathing using the same technique as the walls.
- Consider using metal hurricane straps to securely tie the roof to the walls.
Following proper framing techniques will yield a shed that maintains structural integrity for years of use. Don't cut corners on the framing and assembly.
Roofing
The roof is one of the most important parts of a shed, as it protects the interior from the elements. There are several common roofing materials to choose from:
Asphalt Shingles
Asphalt shingles are the most popular roofing material for sheds. They are affordable, easy to install, and come in a variety of colors and styles. The most commonly used asphalt shingles are 3-tab shingles. Make sure to use roofing felt and drip edge to properly weatherproof the roof.
Metal Roofing
Metal roofs are durable, fire-resistant, and long-lasting. Steel and aluminum are common metals used. Metal roofs can be expensive upfront but require less maintenance over time. They come in panels or shingles. Ensure proper installation for weatherproofing.
Wood Shakes/Shingles
Cedar shakes or shingles provide a rustic, natural look. They need to be installed over solid decking and require regular maintenance. Consider treating them for weather-resistance. Proper ventilation is important to prevent moisture issues.
Rolled Roofing
Rolled roofing is an affordable option made from asphalt saturated fiberglass. It comes in large rolls for easy installation. Use it over solid decking with roofing nails. Rolled roofing won't last as long as other options.
Make sure to install a roof that suits your budget, climate, and aesthetic preferences. Carefully follow installation instructions. Also properly flash and seal around protrusions like vents. With the right materials and techniques, your shed's roof will provide protection for years to come.
Siding & Exterior
Selecting the right siding material for your shed is an important decision that impacts both aesthetics and durability. Here are some of the most popular siding options to consider:
Wood Siding
- Wood siding like cedar and redwood offers a classic, natural look. It can withstand moisture and resists rot and insect damage.
- It requires staining or painting every 3-5 years to protect it from the elements. Unfinished wood will weather to a gray patina over time.
- Types of wood siding include shingles, boards, and sheets. It provides a flexible option for custom looks.
Vinyl Siding
- Vinyl is one of the most popular siding choices due to its affordability and low maintenance. It never needs painting.
- Vinyl is available in a wide range of colors and can mimic the look of wood with texture and patterns. Insulated vinyl improves energy efficiency.
- Durability varies by thickness and quality. Look for vinyl rated for high impact resistance.
- Seams need caulking to prevent water intrusion. It can become brittle and crack over time, especially when exposed to extreme heat or cold.
Metal Siding
- Aluminum, steel, and other metals offer exceptional durability and fire resistance.
- Metal siding is lightweight yet very strong. It requires little maintenance other than occasional cleaning or touch up painting.
- Look for high-quality metals that have special coatings to prevent corrosion, scratching, and denting.
- Metals conduct heat and cold easily, so insulation backing improves energy efficiency.
- Many metal siding styles are available to mimic wood, stucco, stone, and other looks.
When selecting a siding material, consider your climate, desired look, and budget. Proper installation is also key to achieving lasting performance. Combining multiple materials can provide visual interest and highlight architectural details.
Doors & Windows
When building a shed, you'll need to decide what type of doors and windows you want to install. Two of the most popular options are hinged doors and sliding doors.
Hinged Doors
Hinged doors are the classic door style with hinges on one side that allow the door to swing open and closed. Hinged doors are simple to install and use. They only require door framing on one side to attach the hinges. Hinged doors are available in a range of styles from basic slab doors to doors with glass panes or decorative details.
The downside of hinged doors is they swing outwards, which can take up space outside the shed. Hinged doors are also easier for intruders to force open compared to sliding doors.
Sliding Doors
Sliding doors move along a track, rather than swinging open on hinges. They save space because they don't have to swing outwards to open. Sliding doors are also more secure than hinged doors since they can't be forced open as easily.
Installing sliding doors takes more effort because you need door framing across the top and down both sides to attach the track. Sliding doors also need rollers and tracks that allow them to slide smoothly. Overall, sliding doors tend to be more expensive than basic hinged doors.
When deciding between hinged vs sliding doors for your shed, consider the space you have available, your budget, and how secure you want the door to be. Hinged doors work well for small sheds on a budget, while sliding doors are great for larger sheds where space efficiency and security are priorities.
Finishing Touches
Once the major construction of your shed is complete, it's time to add the finishing touches that will really make it feel like a functional building. Here are some of the final steps:
Paint
Painting the exterior of your shed will not only make it look nicer, but will also help protect the wood from damage caused by moisture, UV rays, and pests. Be sure to use high quality exterior paint and properly prepare the wood surface before painting. Apply a primer first, then 2 coats of exterior paint in your desired color.
Trim
Add trim pieces around doors, windows, and corner edges to give your shed a polished look. Trim serves both decorative and functional purposes. Choose exterior-rated trim boards and use galvanized nails to secure them. White trim provides a crisp, clean appearance, but you can stain or paint the trim any color you like.
Electricity
Adding electricity enables you to light your shed and have power available for tools or other needs. Hire a licensed electrician if you don't have electrical experience. They can assess your power needs, run wiring from your home's electrical panel, and install lighting, switches and outlets. Place lights over doors, in corners or wherever illumination is needed. GFCI outlets are recommended for safety, especially if used outdoors.
With these final touches - fresh paint, decorative trim, and electrical wiring - your DIY shed will not only look great, but will be much more usable. Take your time with the finishing steps to create a high-quality shed you'll enjoy for years to come.
