Shed guide · Construction

Cladding protects the building. Framework gives it its strength.

All our frameworks are tanalised. The main range differences are the cladding treatment and thickness, plus the heavier 3x2 framework used for Beast sheds.

Compare Standard, Tanalised and Beast side by side

The three columns below keep the specification, cladding detail, cross-section and framework together, making it easier to compare how each range is constructed.

  • Dip-treated cladding
  • Tanalised 38 × 50mm framework

Framework

What the cladding does

Our rebated shiplap joint is designed to improve rigidity while accommodating the natural movement that can occur as timber changes with the seasons. All the timber cladding we use is suitable for exterior use and can be painted, varnished or stained.

We use slow-grown timber for greater strength, durability and density. It is kiln-dried for extra stability and planed to make painting, varnishing or staining easier.

Why framework matters

Framework is the structural skeleton of the shed: the beams and joists that give the building rigidity and strength. Every range uses tanalised framework. Standard and Tanalised ranges use 38 × 50mm solid timber beams; the Beast range steps up to 3" × 2" CLS, comparable in size to building-grade framework used in modern house construction.

How the frame is assembled matters too. We screw the construction together and use supporting cross-sections where extra strength is needed.

Important:All our shed ranges use tanalised framework, even when the outer cladding itself is dip treated.
