How To Build A Shed

Building your own shed can be a rewarding project that provides you with additional storage space or a dedicated workspace. As opposed to using a shed kit, devising your own shed plan allows you to make the project and space entirely your own.

Whether you’re going for a more elaborate design than what is offered on the market, such as incorporating fascia board for a finished look or implementing double doors and additional windows, we’ve collated a comprehensive guide with step-by-step instructions on how to build your very own garden shed.

Note: Building permits, local building codes and regulations can vary by location, so it’s important to check with your local authorities before starting the shed build construction process.

Additionally, this guide provides a general overview and may not cover every specific detail. It’s always recommended to consult professional builders or contractors if you have any doubts or questions.

Planning and Preparation

1. Determine the purpose and size of your shed: Decide how you will use the shed (e.g., storage shed, workshop DIY shed, garden office etc) and determine the size and dimensions based on your requirements. Knowing how much your shed measures will simplify the proceeding steps. To construct an outer frame, we advise following a specific order of back wall, front wall, and sidewalls, building from the floor up.
2. Choose a suitable location: Select a level area of your property with good drainage. Consider factors such as access, sunlight exposure, and proximity to utilities.
3. Check local regulations: Contact your local building department to obtain necessary permits, guidelines, and information regarding setback distances, height restrictions, and other building requirements.
4. Create a shed design: Sketch a layout and design for your shed frame, including features like windows, doors, ventilation, shelving and the shed roof. Consider using pre-made free shed plans or software to assist in the design process.
5. Gather materials and garden tools: Make a list of all the necessary materials and tools required for the construction. Common materials include lumber, plywood, roofing materials, nails, screws, and concrete. Essential tools may include a tape measure, circular saw, hammer, drill, level, and safety equipment.

Foundation and Site Preparation

1. Clear and level the site: Remove any vegetation, rocks, or debris from the construction area. Level the ground using a shovel, rake, and a level to ensure a solid foundation for your shed base.
2. Determine the shed’s footprint: Mark the dimensions of the shed on the ground using stakes and string. This outline will serve as a guide during the construction process.
3. Excavate for the foundation: Dig post holes or trenches according to your chosen foundation type. Common options include concrete footings, concrete piers, or a gravel foundation.
4. Install the foundation: Follow the specific instructions for your chosen foundation type. This may involve pouring concrete into the footings or setting concrete piers. Alternatively, for a gravel foundation, spread and compact gravel evenly within the marked area.

Framing and Construction

Floor Construction

1. Build the wood floor frame: Construct the shed’s floor frame using pressure-treated timber. Cut and assemble the joists, rim joists, and blocking according to your shed’s dimensions. Secure the the timber frame with nails or screws.
2. Install the floor decking: Lay plywood sheets over the floor joists and shed floor framing then secure them with nails or screws, leaving a small gap between sheets to allow for expansion.

Wall Construction

1. Assemble the wall frames: Cut the wall studs and plates according to your shed’s height and layout. Build each wall frame on a flat surface and then raise them into position. Secure the frames with nails or screws. After completing the construction of the shed’s four sides, ensure that they are straight and level before fastening them to the floor. If you haven’t made a wood floor, you can secure the walls to the wall plates.
2. Install windows and doors: Follow the manufacturer’s instructions to install windows and pre-hung doors/door frames. Ensure your shed window and door components are level and properly sealed. Certain doors come pre-assembled and installed within the panel, while others may arrive separately and require alignment and installation using the included hinges. After placing the door, drill pilot holes and install any sliding bolts or padlocks included (or bought separately) for added security.
3. Raise and secure the walls: With the help of assistants, lift the wall frames and attach them to the floor frame using nails or screws. Use a level to ensure the walls are plumb and square, offering a straight edge.

Roof Construction

1. Build the shed’s roof structure: Construct the roof trusses or rafters according to your shed’s design. Install them on top of the walls, spaced according to the manufacturer’s specifications. Secure them in place.
2. Install roof sheathing: Attach plywood or oriented strand board (OSB) sheets to the roof structure using nails or screws. Leave appropriate overhangs at the edges.
3. Apply roofing materials: Install roof felt or underlayment, followed by your chosen roofing material (e.g. shingles, metal panels). Follow the manufacturer’s instructions for proper installation.

Finishing and Details

1. Install siding or cladding: Apply siding materials (e.g. vinyl, wood, metal) to the exterior walls, following the manufacturer’s instructions and design preferences.
2. Finish the interior: Install insulation, if desired, between the wall studs. Add interior finishes such as drywall or insulated plasterboard, paneling, or plywood. Paint or stain the interior surfaces as desired.
3. Install doors and windows: Hang the doors and install windows securely. Ensure proper insulation and weather sealing around these openings.
4. Add electrical and lighting: If you plan to include electricity in your shed, consult a qualified electrician to design and install the wiring, outlets, and lighting fixtures according to local electrical codes.
5. Include shelving and storage: Install shelves, racks, or cabinets to maximise storage space within your shed. Customise the layout based on your needs.
6. Apply a protective finish: Apply a weather-resistant sealant or paint to protect the exterior surfaces of the shed from moisture, UV rays, and other environmental factors.

Final Touches and Safety Measures

1. Install gutters and downspouts: Direct rainwater away from the shed walls by installing gutters and downspouts. This will help to prevent water damage.
2. Ensure proper ventilation: Add vents or windows that can be opened to allow for proper air circulation and prevent condensation within the shed.
3. Install security measures: Consider adding security features like locks, alarms, or motion sensor lighting to protect your shed and its contents.
4. Maintain safety precautions: Throughout the construction process, prioritise safety by wearing appropriate protective gear, following tool instructions, and taking necessary precautions to prevent accidents.

Remember, building a shed requires careful planning, skill, and attention to detail. It’s essential to prioritise safety and follow building codes and regulations in your area.

If you’re unsure about any aspect of the construction process, consider consulting a professional builder or contractor for guidance.
