5ft x 16ft Apex Shed

Looking to elevate your outdoor storage without compromising on garden space? The 5ft x 16ft Apex Shed is the ideal blend of slender dimensions and serious durability, engineered for UK weather and British back gardens. With its longer-than-average length and compact width, this model is ideally suited for storing everything from gardening gear and patio furniture to bikes, tools, and seasonal items.

Crafted from Swedish pressure-treated redwood, the shed features our signature tongue & groove construction—known for its strength, resilience, and ability to withstand the ever-changing UK climate. Designed for the modern homeowner, this shed brings form and function together in one handsome, hardwearing package.

Built for the British Climate, Ready for Every Season

Unlike many sheds on the market, the 5ft x 16ft Apex Shed is made to stand tall year-round. It’s 12mm tongue & groove cladding creates a tight interlock, ensuring your contents remain safe, dry, and well-protected from rain, frost, wind, and humidity. The robust apex roof design enhances water runoff, while heavy-duty felt and galvanised fixings extend its lifespan.

This shed doesn’t just perform; it adapts. With customisable window placement, you can maximise natural light without compromising security—ideal for workshop use or visibility.

Crafted for Longevity – Quality in Every Detail

The construction of this shed reflects our commitment to premium-grade materials and precision assembly. Everything from the flooring to the fixings has been chosen for endurance:

• 12mm tanalised redwood tongue & groove shiplap walls and roof
• 38mm x 50mm structural framing throughout
• 18mm pressure-treated floorboards with integrated bearers
• 40kg heavy-duty bitumen mineral felt (nail-tacked, not stapled)
• 4mm horticultural glass windows
• Double-nailed cladding and fully screw-fixed frames
• Galvanised hinges, nails, and Brenton padbolts

We never use OSB or chipboard. Only high-grade, pressure-treated timber enters our buildings, ensuring resistance against rot, fungal attack, and insects.

At Flat Pack Sheds, we’re proud to offer expertly built garden buildings that are as easy to assemble as they are to enjoy.
