20′ x 10′ Forest Timberdale 25yr Guarantee Tongue & Groove Pressure Treated Double Door Reverse Apex Shed (6.00m x 3.21m)

Overview

Built to a 20′ x 10′ footprint, this Forest Timberdale shed uses pressure treated tongue and groove timber and a reverse apex roof, backed by a 25 year guarantee against rot. The reverse orientation suits gardens where the shed’s long side faces the main view from the house or path, giving a neater roofline from that angle.

Key Features

• Spacious 20′ x 10′ floor area
• Pressure treated tongue and groove cladding
• 25 year guarantee against rot
• Reverse apex roof orientation
• Wide double doors
• Solid, weather-resistant framing

Roof Types

The reverse apex roof runs its ridge from front to back rather than side to side, a layout many customers prefer when the shed sits with its length facing the garden. It sheds rain just as effectively as a standard apex while presenting a different roofline from the front.

Dimensions

• Overall size: 20′ x 10′ (6.00m x 3.21m)
• Roof style: Reverse apex
• Cladding: Pressure treated tongue and groove timber
• Door: Double door access

Construction

Interlocking tongue and groove boards form a tight, draught-resistant wall, fitted to a solid timber frame built to carry the roof load and stand up to daily use. Because the timber itself is pressure treated rather than surface-coated, protection runs right through the wood rather than sitting on top of it.

Treatment & Guarantee

The pressure treatment process is what allows Forest to offer a 25 year guarantee against rot on this shed, giving long-term confidence without the need for annual re-treatment to maintain the cover.

Doors & Windows / Security

The wide double doors make loading and unloading straightforward, and both can be fitted with a padlock for security. Tongue and groove cladding also helps reduce draughts compared with lighter overlap boards.

Frequently Asked Questions

Is the guarantee transferable? The 25 year guarantee applies to the timber and is tied to the property, so check current terms at the time of any sale.

How does reverse apex differ from apex? The ridge runs the opposite way, which changes how the roofline appears depending on which side faces you.

Does the shed need a base? Yes, a firm, level base is essential for a stable installation.
