Forest Timberdale 10x20 Apex Shed - Double Door - No Windows

Forest Timberdale 10x20 Apex Shed - Double Door - No Windows

The Forest Timberdale 10x20 Apex Shed - Double Door - No Windows is the largest shed in Forest Garden's premium Timberdale collection, expertly handcrafted in Worcestershire to deliver exceptional quality, durability and security. Offering an impressive amount of internal space, this shed is perfect for storing large garden machinery, bicycles, outdoor furniture, tools or creating a spacious home workshop.

Designed with Forest's innovative modular construction system, the Timberdale Shed is easier to assemble than traditional large sheds. The interchangeable framed panels allow you to choose the position of the doors during installation, giving you complete flexibility to create the ideal layout for your outdoor space.

Premium Tongue & Groove Construction

Constructed using high-quality 12mm tongue and groove timber throughout, the Timberdale range contains approximately 30% more timber than many standard garden sheds. This creates an exceptionally rigid and long-lasting structure that is built to cope with the changing British weather while maintaining its attractive appearance.

The entire building is pressure treated to protect against rot and fungal decay and is backed by Forest's outstanding 25-year anti-rot guarantee. Unlike many timber sheds, there is no need for annual preservative treatments, allowing you to enjoy years of virtually maintenance-free ownership.

Strong Floor and Weatherproof Roof

The heavy-duty 12mm tongue and groove boarded floor is supported by pressure treated floor bearers, providing excellent strength for storing heavier items including lawnmowers, tool chests, shelving units, workbenches and power equipment.

The traditional apex roof provides generous internal headroom and encourages efficient rainwater run-off. Constructed using durable 12mm tongue and groove roof boards and finished with premium green polyester felt, it offers dependable weather protection throughout every season.

Maximum Security for Valuable Storage

This model features a windowless design, making it an ideal choice for anyone wanting maximum security and privacy. With no glazing, valuable tools, machinery and equipment remain hidden from view while the enclosed design also helps protect stored items from direct sunlight.

The wide double doors are reinforced with traditional diagonal Z-frame bracing for extra strength and long-term stability. A premium rim lock door latch provides reliable security while allowing convenient access when moving larger items in and out of the shed.

Expertly Handcrafted in Britain

Proudly manufactured in Worcestershire using FSC® certified timber from responsibly managed forests, the Timberdale range combines sustainable materials with exceptional British craftsmanship. Built to provide decades of dependable performance, this premium shed is a practical and attractive addition to any garden.
