Why the Beast is known as the “Bomb Shelter”

Substantial framing, thick interlocking cladding and pressure-treated timber create our strongest shed range.

01

Every timber component Tanalised

Pressure treatment helps protect the building throughout, not just selected visible components.

02

Robust 3" × 2" framework

Substantial planed timber framing gives the shed its exceptionally strong and sturdy structure.

03

Approximately 20mm finished cladding

Heavy 25mm tongue-and-groove boards are planed to an approximately 20mm finished thickness.

04

Protected from the elements

Premium materials and interlocking construction create a dependable long-term outdoor building.

Heavy-duty door hardware

Secure fittings built into the structure

The lock and hinges are fixed through the cladding and substantial framework rather than relying on surface screws alone.

Heavy-duty Beast Shed hasp and staple lock

Heavy-duty hasp and staple

The lock fitting is securely bolted and screwed through the cladding and framework. Once closed, its screws and bolts are concealed.

Hinges bolted through the framework

The hinges are secured through the heavy framework, so simply removing the visible screws does not release the hinge from the building.
