Garden Master GM3018SE Garden Shed

Customise the GM3018SE to Suit Your Site

The Garden Master GM3018SE is highly configurable, allowing you to tailor both the look and layout of the shed to your property and how you plan to use it.

• Extensive Colour Choice: Select from a wide palette of colours for the walls, roof, trim, and door so the shed blends with your home or stands out as a feature.
• Flexible Door Options: Start with the included single door or upgrade to double doors; add extra doors in the opposite end wall, or choose sliding doors where swing space is limited.
• Configurable Door Position: Position doors where they best suit your access and pathways, making it easier to get large or frequently used items in and out.
• Window Placement: Add louvre windows to the front left and/or front right to bring light and ventilation exactly where you need it.
• Adjustable Wall Height: Increase wall height in 50mm steps (up to 300mm) for more headroom and better clearance for tall storage.
• Lighting Options: Incorporate a skylight roof panel if you want additional natural light without adding more windows.
• Interior Fit‑Out: Use shelving brackets, tool hooks, Bruns Tool Grip, and other accessories to create an organised storage system tailored to your gear.

These sheds are designed to be DIY projects, however we also offer a full install service at fixed prices should you prefer someone else to do this for you. Typically a shed of this size would take one of the installers we use *one day*. See shed options for pricing.

DIY Construction & Assembly

Straightforward installation for someone with good DIY skills. Wall sheets are joined with rivets, and the top and bottom channels are drilled and riveted. Once all wall and roof panels are prepared, stand the wall panels up, then drill and rivet them together. The roof panels are installed in the same manner, followed by drilling and riveting the flashings to the shed. Finally, attach the door using the supplied hinges.

If you choose the optional floor kit, the precut runners and floorboards are simply nailed together with a hammer. If using a kitset floor, assemble it before you start erecting the shed.
