4x18ft Apex Shed Ultimate Narrow Garden Storage In today’s world of maximising outdoor space, the 4ft x 18ft Apex Shed is a game-changing solution for homeowners seeking a durable, space-saving garden building. Designed to offer practicality without sacrificing quality or style, the 4ft x 18ft Apex Shed fits seamlessly into narrow outdoor areas—making it perfect for urban side returns, slim garden borders, or compact backyards. Despite its slim profile, this shed provides generous internal storage capacity, making it ideal for storing tools, bikes, gardening equipment, and more.
Designed for Narrow Spaces, Built for Big Storage Needs With a footprint of just 4ft in width, this shed is specifically engineered for those tricky garden layouts where standard-size sheds simply don’t work. Yet at 18ft in length, it offers ample room for storing everything from bicycles, garden tools, and ladders to seasonal items, workbenches, and hobby supplies. Imagine having your garden tools neatly lined up, your lawnmower tucked away, and still space for DIY projects—all in a shed that fits snugly along your fence or home wall.
Premium Construction with Longevity in Mind
Crafted using pressure-treated tongue-and-groove timber, our Apex Sheds not only look great but also offer decades of rot-resistant performance. The pressure treatment process protects the wood from moisture ingress, fungi, and woodworm—crucial for withstanding the UK's unpredictable weather conditions.
Build Highlights: ● Strong Internal Framing: 38mm x 50mm framing for superior structural stability. ● Tongue & Groove Cladding: Interlocking boards for enhanced weather resistance and aesthetic appeal. ● Heavy-duty Roof & Floor: Made from the same high-grade timber with added support beams underneath. ● Mineral Roofing Felt: Provides excellent water runoff and extra protection from rain and snow.
Classic Apex Roof – Style Meets Function The traditional apex roof isn’t just a design choice—it adds extra vertical space, making it easier to store tall items or install shelves along the sides. The peaked roof also encourages efficient water drainage, preventing water buildup and extending the lifespan of the roof covering. This style of roof also complements both classic and modern gardens, adding a touch of rustic charm while remaining highly functional.
