Adjustable Base for a Wooden Shed

We offer a range of high-quality, weather-resistant products that eliminate the need for concrete or digging, giving you a cleaner and more flexible alternative for outdoor construction. Our wooden shed base kits are ideal for a wide variety of structures, including sheds, summerhouses, greenhouses and decking. Whether you’re looking for a strong, reliable base for a wooden shed or a full kit tailored to your garden layout, our products are engineered to provide long-lasting support on uneven or sloped ground.
Screw the head u channel of the Swift levelling device to the frame at equal intervals. Complete this for the whole frame.
Flip the timber frame over so that the bases point to the floor. Slide the templates to the ground and pin them in position.
Move the frame leaving the templates in place, and drill the large centre holes in the ground.
Insert the base plates into the ground. Position the heads and frame over the large centre holes and drop into place.
Adjust each head to the required height and tighten each nut to secure the frame. Use a spirit level to check, and adjust if necessary.
