Forest Timberdale 10x20 Apex Shed - Double Door - 8 Windows - 1 Opening

Designed to make garden storage straightforward, this product is part of our broad selection of wooden sheds, supported by additional garden sheds for sale for a range of outdoor spaces. The Forest Timberdale 10x20 Apex Shed - Double Door - 8 Windows - 1 Opening is a premium-quality timber shed that combines outstanding craftsmanship, impressive storage capacity and a bright, spacious interior. Expertly handcrafted in Worcestershire, this large garden building is ideal for use as a workshop, hobby room, home office or secure storage space for garden machinery, bicycles and outdoor equipment.

Designed with Forest's innovative modular construction system, the Timberdale Shed offers complete flexibility during installation. The interchangeable wall panels allow you to choose the position of the doors and windows, helping you create the ideal layout for your garden while making assembly easier than traditional large timber sheds.

Premium Tongue & Groove Construction

Built using 12mm tongue and groove timber throughout, the Timberdale range contains approximately 30% more timber than many standard garden sheds. The interlocking boards create a strong, rigid and weather-resistant structure that is built to withstand the changing British climate while maintaining its attractive appearance.

The timber has been pressure treated for long-lasting protection against rot and fungal decay and comes with Forest's impressive 25-year anti-rot guarantee. Best of all, no annual preservative treatments are required, giving you years of low-maintenance ownership.

Heavy-Duty Floor and Weatherproof Roof

The durable 12mm tongue and groove boarded floor, supported by pressure treated floor bearers, provides excellent strength for storing heavier equipment including lawnmowers, workbenches, shelving, power tools and bicycles.

The traditional apex roof creates generous internal headroom while allowing rainwater to run off efficiently. Manufactured using robust 12mm tongue and groove roof boards and finished with premium green polyester felt, it offers reliable weather protection throughout every season.

Bright Interior with Natural Light and Ventilation

Featuring eight 4mm toughened safety glass windows, this Timberdale shed benefits from an abundance of natural daylight, making it an excellent choice for anyone using the space as a workshop, hobby room or creative workspace. Toughened safety glass provides increased durability while offering a premium finish.

One opening window allows fresh air to circulate throughout the shed, helping reduce condensation and creating a more comfortable working environment during warmer months.

The wide double doors are reinforced with traditional diagonal Z-frame bracing for additional strength and are secured with a premium rim lock door latch, allowing easy access while keeping your belongings safe.

Expertly Handcrafted in Britain

Every Timberdale Shed is proudly handcrafted in Worcestershire using FSC® certified timber sourced from responsibly managed forests. Combining sustainable materials with exceptional British craftsmanship, this premium shed is designed to provide decades of dependable performance while enhancing any outdoor space.
