Forest Timberdale 10x20 Apex Shed - Double Door - 8 Windows - 2 Opening

The Forest Timberdale 10x20 Apex Shed - Double Door - 8 Windows - 2 Opening is one of the largest and most versatile sheds in the Timberdale range, expertly handcrafted in Worcestershire to provide exceptional strength, premium quality and outstanding durability. With its generous internal space, this shed is ideal for use as a workshop, hobby room, studio or secure garden storage for tools, machinery, bicycles and outdoor equipment.

Designed with Forest's innovative modular construction system, the Timberdale Shed allows you to choose the position of the doors and windows during assembly. This flexible design makes installation easier while allowing you to configure the shed to perfectly suit your garden and available space.

Premium Tongue & Groove Construction

Manufactured using high-quality 12mm tongue and groove timber throughout, the Timberdale range contains approximately 30% more timber than many standard garden sheds. The tightly interlocking boards create a rigid, weather-resistant structure that is built to withstand the changing British climate while maintaining a premium finish.

The timber is pressure treated to provide long-lasting protection against rot and fungal decay and is backed by Forest's market-leading 25-year anti-rot guarantee. With no annual preservative treatments required, you can enjoy years of low-maintenance ownership.

Strong Floor and Weatherproof Roof

The heavy-duty 12mm tongue and groove boarded floor is supported by pressure treated floor bearers, providing the strength needed to store heavier items such as lawnmowers, workbenches, shelving, power tools and other bulky equipment.

The traditional apex roof creates excellent headroom while allowing rainwater to run off efficiently. Built using durable 12mm tongue and groove roof boards and finished with premium green polyester felt, it offers dependable weather protection all year round.

Bright Interior with Excellent Ventilation

With eight 4mm toughened safety glass windows, this Timberdale shed is flooded with natural daylight, making it an excellent choice for anyone wanting to use the space as a workshop, creative studio or hobby room. Toughened safety glass provides excellent durability while giving the shed a premium appearance.

Two opening windows allow fresh air to circulate throughout the building, helping reduce condensation and creating a comfortable environment during warmer months or when spending extended periods working inside.

The wide double doors are reinforced with traditional diagonal Z-frame bracing for additional strength and fitted with a premium rim lock door latch to provide reliable everyday security.

Expertly Handcrafted in Britain

Proudly handcrafted in Worcestershire using FSC® certified timber sourced from responsibly managed forests, the Timberdale range combines sustainable materials with exceptional British craftsmanship. Built to last for decades, this premium shed offers both outstanding performance and timeless garden appeal.
