Customisation

Customisation & Configuration Options

The Garden Master GM3818SE Garden Shed is highly configurable, allowing you to tailor layout, colours and features to suit your site and storage requirements.

Layout & Access

  • Upgrade to sliding doors where space is tight or access is restricted, while retaining secure pad‑bolt locking.

Height & Size Adjustments

  • Increase wall height by up to 300mm in 50mm increments to gain extra headroom or accommodate longer items.

Colour Selection

  • Select Alu‑Zinc or a coloured finish for your shed.

  • Optional corner flashing upgrade for a cleaner, more defined edge detail.

Light, Ventilation & Internal Fit‑Out

  • Add louvre windows for controllable airflow and extra natural light.
  • Include one or two skylight roof sheets to brighten the interior for daytime use.

DIY Assembly

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 & Installation

Straightforward installation for someone with good DIY skills. Wall sheets are joined with rivets, with top and bottom channels drilled and riveted. Once the wall and roof panels are assembled, they are stood up, drilled and riveted together. Flashings are then drilled and riveted to the shed, and finally the door is attached using the supplied hinges. If you are using the optional floor kit, the precut runners and floorboards are simply nailed together with a hammer before you begin assembling the shed.

DIY Difficulty Rating

  • Suited to a competent DIYer; a two‑person job is recommended for handling panels safely.
  • Allow approximately one and a half days for installation for someone with good DIY skills.

Tools Required

  • Power drill
  • 3.3mm drill bits
  • Riveter
  • Hammer (for floor kit)
  • Tape measure
  • Ladder or saw stool
  • Non‑slip gloves
  • Eye protection
  • Saw horses
