Rowlinson Shed in a Box

The Rowlinson Shed in a Box is a practical, affordable alternative to a traditional timber shed—offering versatile outdoor storage that fits perfectly into a range of garden sizes. Whether you’re looking to store gardening tools, protect your motorbike, or shield your firewood from the elements, this shelter has you covered. This compact and effective unit is ideal for gardens where space is at a premium. Constructed with a 35mm diameter steel frame and finished in a premium powder coating, it’s built to resist rust, chipping, peeling, and corrosion. Its patent-pending ShelterLock® 3X stabilisers provide outstanding structural integrity, keeping the shed steady even in tougher conditions. The triple-layer woven polyethylene cover is heat-sealed rather than stitched, ensuring maximum water resistance. It’s also UV-treated inside, outside, and in-between, protecting it from fading, wear, and sun damage over time. The ratchet-tight tensioning system guarantees a snug fit between the cover and frame, and the easy-slide cross rail makes installation and adjustments simple. Available in a range of sizes, the Shed in a Box offers reliable protection for whatever you need to store—without the maintenance demands of a traditional wooden shed.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
