Providing sturdy and secure garden storage for your tools, bicycles and other outdoor equipment, the 11 x 5 Palmako Mia Heavy Duty Lean To Shed (3.3m x 1.7m) features a 3-sided, space-saving design to help maximise your outdoor space.

Premium Build

Expertly crafted from 16mm Nordic spruce tongue and groove, this wooden shed includes readymade wall elements, ensuring a straightforward assembly, incredibly robust structure and complete weatherproof protection for your tools and equipment.

Floor and Roof

Both the floor and roof are built from 16mm tongue and groove, which is renowned for its weather resistance, durability and strength. Treated foundation joists protect the floor from ground moisture, while the fashionable lean-to roof ensures excellent rainwater runoff.

Select a Roof Covering

Please be advised that the roof does not include a cover as standard. Select from SBS or Roof Felt Underlay as an optional upgrade.

(SBS weatherproof roof covering is a thick, torch-on felt with an exceptionally long lifespan and outstanding weatherproof qualities. Unless you possess advanced DIY skills, we recommend hiring a professional installer.

Roof Underlay Felt is simple to nail on to the garden building but is only designed as a temporary solution until you have added a permanent weatherproof roof cover upgrade.)

Doors and Windows

You can gain storage-friendly access to the shed’s interior via solid wood double doors. They are fitted with a latch and padlock fixing, so rest assured that your valuable tools will remain completely safe from unwanted attention (padlock not included).

The opening window provides plenty of natural light and welcome ventilation if you’re hard at work inside. It is made from plexiglass, which is renowned for being both tougher and more transparent than conventional glass.

Simple Assembly, Generous Warranty and Choice of Sizes

Available in 2 sizes, this Palmako garden shed comes with a generous 5-year manufacturer’s parts warranty, as well as instructions and a fixings kit to help you achieve a straightforward assembly. The 3-sided design allows you to build this shed to lean to the left or right of a wall.

Wood Care

This wood shed is supplied untreated. We recommend that an initial anti-fungal treatment is applied upon assembly and repeated annually, thereafter, to support the warranty. Alternatively, you could paint your new shed for that personal touch.
