Frame & structure
Pressure-Treated Timber Frame
The 38×50mm skeleton behind every building, timber or composite.

Why we build with this
The frame is the part no one sees and everyone relies on, so we don't vary it. Every building — timber or composite, cheapest or Heavy Duty — stands on the same 38×50mm pressure-treated skeleton. Spending the same on the structure regardless of cladding is how we keep every building square, strong and honest.
Dimensions

Measurements
Framing timber shown in section — 38mm × 50mm, pressure-treated.
Whatever's on the outside, every building in the range is built on the same 38×50mm pressure-treated timber frame. The cladding, roof and colour choices change the look and the warranty — the frame underneath doesn't change at all.
Benefits
- Identical framework across every range — timber and composite alike
- Pressure-treated against rot before assembly
- The same structural spec whichever cladding or roof you choose
