12′ x 8′ Forest Timberdale 25yr Guarantee Tongue & Groove Pressure Treated Double Door Reverse Apex Shed (3.64m x 2.61m)
Overview
This 12′ x 8′ Timberdale shed uses a reverse apex roof, where the ridge runs along the width of the building rather than the depth. Built from pressure treated tongue and groove timber, it comes with a 25 year guarantee against rot for long-term peace of mind and reliable garden storage.
Windows are fitted as standard, bringing useful daylight into the interior. For a standard apex layout at the same size, see the 12×8 Timberdale Double Door Apex Shed elsewhere in the range.
Key Features
- 12′ x 8′ (3.64m x 2.61m) reverse apex shed
- Pressure treated tongue and groove timber
- 25 year guarantee against rot
- Windowed design for natural daylight
- Double doors for wide access
Roof Types
The reverse apex roof still gives the headroom of a standard apex roofline, but with the ridge turned to run along the width of the shed. This can work better for gardens where the shed backs onto a boundary along one of the longer sides.
Dimensions
- Overall width: 12′ (3.64m)
- Overall depth: 8′ (2.61m)
- Roof style: reverse apex
- Windows: fitted as standard
Construction
Interlocking tongue and groove boards give a tighter, more weatherproof fit than plain overlap cladding, helping to keep the interior dry through the seasons and reducing draughts around the frame. Pressure treatment forces preservative into the timber during manufacture, supporting the long guarantee period.
Treatment & Guarantee
The 25 year guarantee against rot reflects the pressure treatment used on this timber. We still suggest checking cut edges and joints occasionally and touching these up with a matching preservative if required after assembly.
Doors & Windows
Double doors give wide access for garden equipment, and the fitted windows bring in useful daylight throughout the day. A windowless version of the same reverse apex layout is the 12×8 Timberdale Windowless Double Door Reverse Apex Shed.
