Garden Master GM3823 Garden Shed

Customisation & Layout Flexibility

The Garden Master GM3823 is highly configurable, allowing you to set up the shed to match your site conditions and how you use your space.

• Door choices: Select single or double doors, in hinged or sliding formats, depending on your access needs and available clearance.
• Door positioning: Place doors on the front, back, or end walls, and adjust the location of extra doors to create convenient entry points.
• Window placement: Add louvre windows on front, sides, and back walls to capture natural light and airflow where you need it most.
• Wall height options: Increase wall height by +150mm or +300mm to give extra headroom or to accommodate taller equipment.
• Lighting options: Add one or two skylite roof sheets to brighten the interior without needing power.
• Colour selection: Individually select colours for walls, roof, trim, and doors to coordinate with your house or garden structures.
• Interior fit-out: Use optional shelves, tool hooks, and frame kits to create organised storage or a compact workshop layout.

Optional Accessories & Upgrades

Tailor the Garden Master GM3823 Garden Shed to how you work and store your gear with a wide range of add-ons.

• GM3823 Wood Floor Kit – Precut runners and floorboards form a dedicated timber floor inside the shed, helping to keep contents off the ground.

• Frame Master Kit (Sure Frame or Kwik Frame) – Additional framing support options to enhance structural rigidity.
• Corner Flashing Upgrade – Upgraded corner trims for a neater, more finished look and added edge protection.
• Single or Double Doors – Configure your shed with single or double doors for the access width you need.

• Door Location Changes – Move the included or extra doors to front, back, or end walls to suit your site layout.
• Extra Single or Double Doors – Add additional doorways for multi-access storage and easier movement through the shed.
• Cabin Hooks – Keep doors safely secured open while you work or move items in and out.

Colour Options

Choose from Alu-Zinc or a wide selection of colours for walls, roof, trim, and doors, including Desert Sand, Grey Friars, Gull Grey, Iron Sand, Karaka, Sandstone, Smooth Cream, Ebony, Slate Grey, and Titania. Mix and match components to create a shed that coordinates with your home and landscaping.

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. The GM3823 is supplied as a kitset with high-tensile steel wall and roof sheets and matching channels.

• Wall sheets are joined with rivets into top and bottom channels, which are drilled and riveted.
• Once all wall and roof panels are assembled, stand the wall panels up, then drill and rivet them together.
• Fit the roof panels in the same manner, then drill and rivet the flashings to complete the shell.
• Finally, attach the door using the supplied hinges.
• If using the optional floor kit, assemble the precut runners and floorboards first, then build the shed on top.

DIY difficulty rating: Competent DIY project, typically a two-day build for a capable home handyman or handywoman.
