Setting up a shed requires a solid, reliable base to ensure its durability and stability. At Summerhouse24, we understand the importance of a proper foundation, which is why we offer tailored foundation kits designed to make the process simple and hassle-free. Here, our experts provide a clear, step-by-step guide to help you install your foundation kit with ease.

Why use a foundation kit?

Choosing a foundation kit for your shed offers several benefits:

• Tailored Fit: Each kit is specifically designed to match your Summerhouse24 garden house or shed model.
• Ease of Installation: No need to pour concrete or struggle with uneven ground—the kit simplifies the entire process.
• Durable and Stable: It ensures the shed remains level and secure, protecting it from shifting or water damage.
• Portable: If you need to relocate your shed, the foundation kit can be moved too.

Here are the main features and benefits of Summerhouse24 base foundation kit.

• The system gives you a 20 cm adjustment margin to achieve a level surface across the frame.
• No concrete or stonework is necessary, so you don’t need heavy equipment.
• In addition to the metal brackets, Summerhouse24 supplies you with the wooden frame that enables you to build your structure directly on top. You do not have to get a suitable substructure yourself.
• This DIY foundation system is up to 80% cheaper than a concrete foundation. If you are using our cabin installation service and would like our installers to assemble this base as part of the installation then you need to select “Full Kit & Install”.
• Should you decide to move your cabin or move house, this base can be easily dismantled and transported.
• Our foundations can be used for any garden house up to 45m².

The innovative foundation kit system can carry the weight of the house many times over and can be built by any DIYer who can use a cordless screwdriver and spirit level.

Tools and materials you’ll need

To install your foundation kit, gather the following:

• Foundation kit from Summerhouse24 (specific to your shed model)
• Spade or shovel
• Rake
• Spirit level
• Gravel or crushed stone
• Weed membrane
• Rubber mallet
• Tape measure
• Tamper or plate compactor

Step-by-step installation guide

Step 1: Plan and review the foundation base layout

• After placing your order, Summerhouse24 provides a foundation base plan tailored to your shed model. This plan marks the exact locations of the support points.
• Review the foundation layout and ensure the area chosen for the installation matches the plan dimensions.
• Clear and Prepare the Ground: Start by selecting an ideal spot in your garden. Ensure the area is relatively flat, has good drainage, and is clear of vegetation. A stable and even surface is essential for a durable shed base. Clear away any grass, plants, and debris using a spade. Level the area with a rake, and lay a weed membrane over the entire space to prevent weeds from growing under the shed.

Step 2: Assemble the foundation base frame

• Lay out the timber components of the base frame on the ground.
• Following the provided instructions, assemble the base frame by connecting the timber pieces securely.
• Use screws and a drill to fasten the joints. Ensure all corners are tightly connected.

Step 3: Align and measure the diagonals

• Check that the base frame is perfectly square by measuring the diagonals. Both diagonals should be equal in length.
• Adjust the frame if necessary to achieve perfect alignment, as this is crucial for a stable shed base.

Step 4: Attach support legs

• Screw a nut onto each threaded bar of the support legs, positioning it approximately at the halfway point for adjustment flexibility later.
• Attach the adjustable support legs to the base frame at the specified locations.

Step 5: Position and mark the frame

• Ensure the frame is level and correctly positioned. Use a marker or stakes to mark the ground where each support leg will be installed.
• Flip the completed base frame over and position it in the desired location for your shed.
• For added stability, anchor the frame to the ground using the stakes provided in the kit. This step is beneficial if your area experiences strong winds.

Step 6: Drill holes for threaded bars

• The holes should be deep enough to anchor the threaded bars of the support legs securely.
• Temporarily remove the base frame and drill holes into the ground at the marked locations.

Step 7: Install the base frame and support plates

• Lift the foundation base frame into place, aligning the support legs with the drilled holes.
• Insert the threaded bars into the ground and secure them by tightening the nuts.
• Install the metal support plates at the base of each leg to provide additional stability.

Step 8: Final adjustments

• Double-check that the base frame is level in all directions using a spirit level. Tap the frame with a rubber mallet as needed to level it.
• Adjust the height of the support legs as needed by turning the nuts on the threaded bars.
• Once everything is aligned and level, tighten all screws and nuts to secure the base frame.

Tips for a smooth installation

• Check the weather: Avoid working in rainy conditions, as it’s harder to level the ground.
• Check the ground: Ensure the area is free from debris, vegetation, and uneven surfaces before starting.
• Use proper tools: A spirit level, drill, and marker are essential for accurate assembly.
• Follow the instructions: Summerhouse24 provides detailed guides with the kit. Refer to them throughout the process.
• Work in teams: Some steps, such as flipping and positioning the base frame, may require two people.

Benefits of a foundation kit

• Level surface: Ensures doors and windows operate smoothly.
• Improved drainage: Gravel prevents water from pooling around the base.
• Stability: Provides a secure foundation, even in windy conditions.

Installing a foundation kit is a practical, efficient solution for setting up a shed or any garden room. With these simple steps and expert guidance from Summerhouse24, you can ensure your shed has a strong, stable base without the hassle of concrete.
