Product Information

Forest Beckwood 20x10 Reverse Apex Shed - 8 Windows - Double Door

The Forest Beckwood 20x10 Reverse Apex Shed with 8 Windows and Double Doors is a premium, large-capacity garden building designed for those needing exceptional storage space. Built in Britain for British gardens, this substantial wooden shed combines traditional styling with strong, durable construction, making it ideal for storing everything from garden tools and bikes to machinery, outdoor equipment, fishing gear and much more. Featuring Forest Garden’s improved fully modular design, the shed is made using smaller interchangeable sections, making it easier to handle, transport and assemble compared to traditional large-panel sheds. The robust pressure treated shiplap cladding provides a strong outer structure, with interlocking boards helping to create a weather-resistant and watertight finish.

Durable Pressure Treated Timber Construction

Built with strength and longevity in mind, the Beckwood 20x10 Reverse Apex Shed features premium 12mm shiplap cladding supported by sturdy 28 x 28mm framing and pressure treated floor bearers. The pressure treatment process helps protect the timber from rot and decay, and the shed comes with an impressive 25-year anti-rot guarantee for added peace of mind. Unlike many standard sheds that use OSB flooring, this model includes a robust tongue and groove boarded floor. This provides a stronger foundation, making it suitable for storing heavier items such as lawnmowers, garden machinery, bicycles, tools and workshop equipment.

Spacious Reverse Apex Design with Weatherproof Protection

With its huge 20x10 footprint, this reverse apex shed offers an exceptional amount of storage space, giving you plenty of room to organise your belongings or create a dedicated workshop area. The traditional reverse apex roof design not only enhances the appearance of the shed but also provides excellent internal height and usability. The roof is constructed using an 8mm solid sheet material and finished with a durable green mineral felt covering. This provides reliable protection against rain, wind and changing weather conditions, helping to keep your stored items safe and dry throughout the year.

Secure Double Doors and Acrylic Glazed Windows

The wide double doors make accessing the shed simple, even when storing larger items. The doors feature a reinforced double-Z frame design, helping to improve strength and prevent movement over time. Security is enhanced with hidden hinges and a heavy-duty traditional pad bolt, helping to keep your belongings protected (padlock not included). The eight fixed windows feature durable acrylic glazing, allowing natural light into the shed while providing a safer and more impact-resistant alternative to traditional glass. Acrylic glazing is designed to remain clear without yellowing or fading over time.

UK Manufactured Quality and Easy Assembly

Handcrafted in the UK using FSC® certified timber from sustainable sources, the Forest Beckwood 20x10 Reverse Apex Shed offers excellent build quality and long-lasting performance. Supplied flat packed with all required fixings and clear assembly instructions, the modular construction makes installation easier and more manageable. The shed is delivered free to most UK addresses using Forest Garden’s White Glove Delivery Service, ensuring it is placed where you need it in your garden, with all packaging removed for your convenience.
