6ft x 16ft Apex Shed

Experience unrivalled durability and generous storage space with our expertly crafted 6ft x 16ft Apex Shed—the perfect outdoor solution for those who require room to store, work, and organise without compromise. Designed for British gardens and engineered with robust materials, this shed offers exceptional strength, stability, and weather resistance all year round.

A Shed That Does More Than Store

This spacious apex garden shed is not just a storage space—it’s a reliable structure built to protect everything from power tools and garden furniture to bicycles and heavy equipment. The extended 16ft length offers enough room to divide the space into dedicated zones, whether you’re planning a DIY workshop or storing bulky items.

Constructed from Swedish pressure-treated redwood, the shed features tongue-and-groove shiplap cladding to keep out rain and damp. The interlocking design enhances insulation and structural integrity, providing a more solid, more weatherproof, and far longer-lasting shed than standard overlap builds.

Superior Build Quality

Each 6ft x 16ft Apex Shed is handcrafted with precision and care, using only high-grade timber—never OSB or chipboard. The fully framed and screwed panels ensure a rock-solid frame, while the 18mm floorboards and thick bearers provide a firm, raised base ideal for heavy-duty storage.

Product Features at a Glance:

• 12mm Pressure Treated Tongue & Groove Shiplap Cladding
• 38mm x 50mm Framing Throughout (Walls, Floor & Roof)
• 18mm Heavy-Duty Floorboards with Integral Bearers

Designed for UK Weather

Whether it’s wind, rain, or snow, this shed is made to handle it all. Pressure-treated and tanalised timber protects against rot, insect infestation, and moisture. So whatever the season, you can count on the shed to stay strong, dry, and secure.
