5ft x 15ft Apex Shed

Long enough to store serious kit, yet slim enough to suit most gardens, the 5ft x 15ft Apex Shed is the shed that delivers on every level. If you’ve been searching for a structure that combines rugged durability, sleek design, and extended storage, your wait is over. Whether you’re housing garden machinery, bikes, tools, or patio furniture, this shed is built to safeguard your essentials through all seasons.

Crafted from tanalised Swedish redwood and built using superior tongue and groove joinery, this apex shed stands tall against the unpredictable British climate. Its elongated frame and versatile layout make it the perfect blend of practicality and presence.

Built for British Weather – Designed for Everyday Use

Let’s face it—UK weather can be unforgiving. That’s why every 5ft x 15ft Apex Shed is engineered with precision-milled, interlocking timber panels that naturally repel water and resist wind. Add in a heavy-duty floor and robust internal framing, and you’ve got a garden building that’s not only spacious but seriously secure.

Durable Construction You Can Trust

No chipboard. No shortcuts. You can rely on quality timber and craftsmanship.

Core construction details include:

• 12mm pressure-treated redwood tongue & groove cladding
• 38mm x 50mm framing throughout for reinforced stability
• 18mm heavy-duty floorboards with integrated bearers
• 12mm tongue & groove roof with 40kg bitumen felt (nail-tacked for longevity)
• 4mm horticultural glass windows (custom placement available)
• Galvanised ironmongery and Brenton pad bolts included
• Double-nailed cladding, screw-fixed framework – no staples here

Even heavy items like log splitters, lawnmowers, or workbenches are no problem with this shed.

Ideal for Narrow Gardens with Growing Needs

This mid-size shed is a real workhorse. Its longer footprint makes it ideal for narrow gardens, walkways, or alongside fences. Yet it still leaves room to move around freely inside. If upgrading from a smaller model or making space for seasonal storage, the 5ft x 15ft Apex Shed offers the perfect in-between.
