Garden Master GM3815 Garden Shed

Customisation & Layout Flexibility

The Garden Master GM3815 Garden Shed is designed to be configured around your site and how you use your outdoor space. A wide range of colour, door, window, and height options make it easy to create a shed that fits both your backyard and your storage needs.

Configure to Suit Your Site

• Door Positioning – Place the main door on the long wall or move it to an end wall to align with paths, fences, or access ways.
• Extra Doors – Add extra single or double doors, including end‑wall options, for multiple access points to different areas inside the shed.
• Hinged or Sliding Doors – Choose standard hinged doors or upgrade to sliding doors where external swing space is tight.

Windows & Light

• Louvre Windows – Add louvre windows to the front, sides, or back of the shed to bring in natural light and airflow where you need it most.
• Skylite Panels – Include one or two skylite roof sheets for extra overhead light, ideal if wall space is needed for shelving or tool storage.

Height & Interior Setup

• Extra Wall Height – Increase the wall height by up to 300mm (in 50mm increments) to create more standing room and better storage for taller or longer items.
• Internal Organisation – Add tool hooks, Bruns Tool Grip, and shelf brackets to set up dedicated zones for tools, bikes, and garden gear, keeping the floor area clear.

Colour Coordination

Select matching or contrasting colours for the walls, roof, trim, and doors to complement your home, fences, and other outdoor structures.
