Customisation

Customisation & Layout Options

The Garden Master GM3023 Frame Master Garden Shed is highly configurable, allowing you to tailor the layout, access and appearance to suit your site and how you work.

Door Layout & Access

  • Choose between a standard single door or upgrade to double doors for wider access.
  • Select hinged or sliding doors to best suit tight spaces or clearance restrictions.
  • Adjust the main door location from the default position to the front or back wall, or move it to an end wall.
  • Add extra single or double doors and choose where those extra doors are located for multi‑side access.

Windows, Light & Headroom

  • Add louvre windows to the front, sides or back of the shed to bring in light and fresh air.
  • Increase natural light from above with one or two skylite roof sheets.
  • Extend the shed wall height by +150mm or +300mm to create additional headroom or accommodate taller equipment.

Colour Coordination & Finishing Touches

  • Specify wall, roof, trim and door colours independently from a wide palette, including Alu‑Zinc and multiple Coloursteel‑style finishes.
  • Upgrade to corner flashings for a sharper, more finished external appearance.

By combining door placement options, additional doors, window positions, colour choices and wall‑height upgrades, you can configure this shed to fit neatly into your available space while keeping access and natural light exactly where you need them.
