Description
The 12x8 Forest Timberdale Apex Shed is a superior-quality building, engineered for those who require maximum space, natural light, and accessibility. Its classic apex roof design maximises headroom along the central ridge, perfect for storing tall items. Wide-opening double doors on the 8ft gable end provide effortless access for bulky equipment, while four large windows along the side flood the interior with light, creating an ideal working environment. Built with a robust, double-framed construction, this shed is a durable and practical centrepiece for any garden.
Quality is evident in every detail. The shed features premium 12mm tongue and groove cladding on a 66 x 33mm internal frame throughout, including the robust floor and roof, ensuring a weather-tight and resilient structure. The heavy-duty floor is supported by Pressure-Treated bearers, elevating it from the ground to prevent moisture ingress. The roof is finished with a premium 40g reinforced-polyester mineral felt covering (colour may vary). Four large opening windows provide excellent ventilation and light; all are glazed with 4mm toughened safety glass. The secure double doors are internally braced with "Z" framing, Smooth Planed All Round (PAR), and are secured with a high-quality rim lock, offering easy access and reliable security.
Pressure-Treated Wood with a Timberdale Guarantee – Built to Last and Minimise Maintenance:
This Timberdale shed has been pressure-treated, forcing preservatives deep into the timber grain for complete protection against rot. This superior treatment is backed by an unbeatable 25-year anti-rot guarantee, the longest on the market. The treatment may leave a greenish tinge on the wood; this is normal and will grey over time.
The shed is completely maintenance-free, meaning it will never require retreating with a preservative, EVER. With a Timberdale Shed, you save an estimated £200 in time and treatment costs, compared to dip-treated sheds.
The manufacturer advises that if you want to paint your timber shed with a different colour, ensure the treatment you choose is recommended for pressure-treated timber.

Fully Modular Design
This shed features an improved, fully modular design, allowing full interchangeability between panels of the same size. It is delivered in smaller, easier-to-handle sections that make assembly more straightforward. This design uses more timber, resulting in a significantly more robust final build and greater flexibility in how you configure the shed.
Walls, Floor, and Roof
This shed boasts a premium 12mm tongue and groove cladding on a robust 66mm x 33mm internal frame, delivering a superior, weatherproof finish that resists warping. The floor is also a robust 12mm T&G interlocking board, strong enough for heavy items and supported by pressure-treated bearers to protect against ground damp. The 12mm T&G roof is finished with a high-grade, 140g reinforced polypropylene-backed mineral felt, ensuring the building and its contents remain dry and protected.
White Glove Delivery Service
This shed is delivered using Forest's premium White Glove Delivery Service. The specialist team will deliver the components directly to your chosen spot in the garden, saving you the effort of heavy lifting. As part of this service, they will also remove and take away all packaging, leaving your garden tidy and ready for assembly.
Optional Upgrades:
Professional Installation:
This wooden shed is supplied flat-packed for self-assembly. For ultimate convenience, you can choose our professional installation service.
Once your order is placed, the manufacturer’s installation team will send a short pre-installation questionnaire. This simple check confirms that your site is suitably flat and level, ensuring the installation day runs smoothly.
If your foundation is prepared and access is clear, the expert installers will handle the complete build. Please note that the installation team cannot dismantle or remove old buildings.
Whether you build the shed yourself or use our service, please ensure a 24-inch (60cm) clearance is left around the entire structure. This space is essential for both the assembly process and any future maintenance.
