Premium Build Quality
Manufactured using 12mm Tongue & Groove timber throughout, the Timberdale Shed contains approximately 30% more timber than many standard garden sheds, providing exceptional rigidity, durability and structural strength. The solid Tongue & Groove walls, roof and floor deliver outstanding weather protection while ensuring the building remains stable and secure for years of everyday use.
The heavy-duty Tongue & Groove floor is supported by pressure-treated floor bearers, making it suitable for heavy machinery, workbenches, shelving and larger storage requirements. The reverse apex roof is constructed from solid Tongue & Groove boards and finished with premium green polyester felt for reliable weather protection throughout the seasons. Decorative smooth planed finials and barge boards complete the building with a traditional, high-quality finish.
Designed for Long-Term Performance
Pressure treated throughout, the Timberdale Shed is protected against rot and fungal decay without the need for annual preservative treatments. Supported by a market-leading 25-year anti-rot guarantee, this premium garden building is designed to provide decades of reliable performance with minimal maintenance.
Manufactured in the UK using FSC® certified timber and other responsibly sourced materials, the Timberdale range combines expert British craftsmanship with environmentally responsible timber sourcing.
Bright, Spacious and Secure
The impressive internal space provides ample room for workbenches, storage systems, ride-on lawn mowers, motorcycles, bicycles, power tools and larger garden machinery. The wide double doors, reinforced with traditional diagonal "Z" framing, make it easy to move large equipment in and out while maintaining exceptional strength and durability. A high-quality rim lock provides added security for valuable belongings.
The eight toughened safety glass windows allow generous amounts of natural daylight into the shed, while the single opening window provides adjustable ventilation to improve airflow, reduce condensation and maintain a comfortable working environment.
