6ft x 18ft Apex Shed

Looking for a shed that delivers on durability, security, and space? The 6ft x 18ft Apex Shed is expertly designed for homeowners who need extended storage without compromising quality. Crafted for strength and style, this long-format garden building is ideal for anyone seeking reliable shelter for tools, bikes, garden furniture, or workshop gear.

Built with weather-resilient tongue and groove cladding, the structure is engineered to withstand harsh British conditions. Whether dealing with driving rain or freezing temperatures, this shed keeps everything safe and dry. The added length allows for well-organised storage, with generous headroom making it comfortable to move about inside.

Superior Timber Construction

Unlike standard overlap sheds, our tongue-and-groove panels create a tight seal. This interlocking method significantly reduces water ingress while enhancing the building’s structural rigidity. Reinforced flooring ensures that even the heaviest tools and equipment can be stored without concern.

Timber Specifications:

• 12mm Pressure Treated Swedish Redwood Tongue & Groove Shiplap
• 38mm x 50mm Framing throughout
• 18mm Floorboards with integral bearers for raised elevation
• 12mm Roof panels using the same durable tongue and groove cladding
• 4mm Horticultural Glass for superior clarity and durability
• 40kg Heavy Duty Modified Bitumen Mineral Felt, individually nail-tacked
• Galvanised hinges and Brenton padbolts fitted as standard
