Forest Beckwood 8x12 Apex Shed - No Windows - Double Door

The Forest Beckwood 8x12 Apex Shed with Double Doors and No Windows is a secure, spacious garden building that's built in Britain to cope with the British climate. Its windowless design offers enhanced privacy and security, making it ideal for storing valuable tools, bicycles, garden machinery and outdoor equipment out of sight. Constructed from premium 12mm pressure-treated shiplap tongue and groove cladding, the interlocking boards create a strong, weather-resistant seal that helps keep the contents dry all year round. The shed also features Forest Garden's fully modular design, with smaller interchangeable panels that make handling, transportation and assembly much simpler.

Built for Strength & Durability

Designed to provide years of dependable use, this Beckwood shed features 30% thicker framing than many standard timber sheds, using robust 28mm x 28mm pressure-treated timber throughout the structure. The pressure treatment protects against rot and fungal decay, allowing Forest Garden to offer a 25-year anti-rot guarantee, with no need for annual preservative treatments. The traditional apex roof not only gives the shed a classic appearance but also provides generous headroom while allowing rainwater to run off efficiently.

Heavy-Duty Floor & Weatherproof Roof

Unlike many sheds that use standard OSB flooring, this model includes a durable 12mm tongue and groove boarded floor, offering the strength needed for storing heavier items such as lawnmowers, workbenches, shelving units and power tools. The roof is manufactured from 8mm solid sheet board and finished with a durable mineral felt covering, providing reliable protection from the elements throughout the year.

Enhanced Security

With no windows, this shed keeps valuable items completely hidden from view, making it an excellent choice for secure garden storage. The wide double doors make moving larger equipment in and out easy and are reinforced with a sturdy double Z-frame for extra strength. Hidden hinges help reduce vulnerable access points, while the heavy-duty pad bolt (padlock not included) provides a secure locking system for added peace of mind.

Easy Assembly & White Glove Delivery

The modular construction makes the shed easier to assemble, thanks to manageable panel sizes designed for quicker installation. Manufactured in the UK using FSC® certified timber from sustainable sources, the shed is supplied with all required fixings and easy-to-follow assembly instructions. It also includes Forest Garden's White Glove Delivery Service, meaning it will be delivered directly into your garden with all packaging removed.
