Rowlinson Workshop 9x18ft Garden Shed / Storage

The Rowlinson 9x18ft Workshop is the ultimate solution for those needing a versatile, spacious outdoor building that can serve as a workshop, hobby space, or large-scale storage. Whether you're a keen woodworker, an avid gardener, or simply need somewhere to house bikes, tools, and outdoor gear, this expansive workshop offers plenty of room to do it all comfortably. With its impressive 9x18ft footprint, there’s space to set up workbenches, shelves, and still have room left over for equipment and materials. The apex roof and high eaves give excellent vertical height, making the interior feel airy and accessible for users of all heights.

Bright, Comfortable, and Easy to Access

Thanks to twelve fixed styrene-glazed side windows and two front windows, the interior of the workshop is flooded with natural daylight. This bright environment makes it ideal for daytime use, whether you’re potting plants, fixing machinery, or simply sorting garden tools. The shatter-resistant styrene glazing provides a safe alternative to traditional glass while allowing for excellent visibility inside. The double doors are wide enough for wheeling in larger items, from lawnmowers to bikes, and feature tongue and groove cladding with double ‘Z’ bracing for added strength and stability. Robust zinc-coated hinges help ensure long-lasting performance and secure closure.

Durable Materials for Long-Term Use

This workshop is constructed using 12mm European kiln-dried tongue and groove shiplap cladding, offering excellent protection from the elements. The roof is made from moisture-resistant OSB and finished with a premium-grade mineral roofing felt, ensuring durability in all weather conditions. The structure is supported by strong 45x28mm and 35x28mm internal framing, giving you confidence in its long-term performance. Supplied in a dipped honey-brown finish, it blends naturally into garden surroundings and can be further customised with paint or stain. And, importantly, all timber is sustainably sourced, making this an eco-conscious choice too.
