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 roofline, which simply turns the ridge to run along the width rather than the depth of the building. Built from pressure treated tongue and groove timber, it carries a 25 year guarantee against rot.
Windows are fitted as standard, and the layout suits gardens where the roof ridge needs to run a particular way. For a standard apex version of the same size, see the 12×8 Timberdale Double Door Apex Shed.

Roof Types
A reverse apex roof still rises to a central ridge for good headroom, but the ridge runs along the width of the shed rather than the depth. This can suit certain garden layouts better, particularly where the shed sits against a boundary on one of the longer sides.

Construction
Tongue and groove boards interlock along their edges for a tighter fit than plain overlap cladding, helping keep the interior dry. The timber is pressure treated during manufacture, which is what supports the shed’s long guarantee period against rot.
Treatment & Guarantee
Pressure treatment is what allows this shed to carry its 25 year guarantee against rot when properly maintained. Check cut edges and joints occasionally and touch these up with a compatible preservative if needed.
Doors & Windows
Double doors open wide for easy access with mowers, bikes and garden furniture, and windows bring in useful daylight. For a windowless reverse apex version of the same size, see the 12×8 Timberdale Windowless Double Door Reverse Apex Shed.
