Product Information

Forest 4LIFE Apex Shed 10x20 Double Door - No Windows

The Forest 4LIFE Apex Shed 10x20 with Double Doors and No Windows is the largest and most secure shed in the Forest 4LIFE overlap range. Offering an impressive amount of internal space, it's perfect for storing large garden machinery, tools, bicycles, outdoor furniture or creating a dedicated workshop. The windowless design provides additional privacy and security, making it ideal for keeping valuable equipment safely out of sight.

Part of Forest Garden's premium 4LIFE range, this shed features fully modular panels that make transportation easier, simplify assembly and create a much stronger overall structure by using more timber throughout the build.

Built to Last for Years

Constructed from traditional 7mm straight-cut overlap timber boards, the shed allows the timber to naturally expand and contract with changing weather conditions while encouraging rainwater to run off effectively.

The walls are reinforced with framing that is approximately 30% thicker than many standard overlap sheds, providing outstanding strength and stability. Every shed is pressure treated to protect against rot and fungal decay, allowing Forest Garden to offer an industry-leading 25 Year Anti-Rot Guarantee. Best of all, there is no need for annual preservative treatments, making maintenance simple and hassle-free.

Heavy-Duty Floor and Weatherproof Roof

Unlike many standard sheds that use OSB flooring, the Forest 4LIFE Apex Shed is fitted with a robust 12mm solid timber floor. This durable construction is ideal for storing heavier equipment such as ride-on lawnmowers, workbenches, shelving units, bicycles and power tools.

The roof is manufactured from strong 8mm solid sheet boarding and finished with a weatherproof green mineral felt covering, providing dependable protection from the elements throughout the year.

Maximum Security and Practical Design

The windowless design offers enhanced security by preventing valuable items from being visible from outside. Combined with the reinforced double doors, this makes the shed an excellent choice for secure storage or use as a workshop.

Additional features include:

  • Double Z-framed doors for increased strength and reduced movement
  • Hidden hinges that cannot be accessed from outside
  • Padlock-ready hasp and staple latch (padlock sold separately)
  • Traditional apex roof with smooth-planed barge boards and decorative diamond finial

Easy Assembly with White Glove Delivery

Manufactured in the UK using FSC® certified timber and other responsibly sourced materials, this premium shed includes all necessary fixings and clear assembly instructions for straightforward installation.

Forest Garden's White Glove Delivery Service is included, meaning the shed is delivered directly into your garden with all packaging removed, making the installation process even easier.
