The rafter ends. The garden pergola has sculpted rafter and runner ends — a shaped profile on the end of each rafter that gives the roofline a more traditional, decorative finish. The box build uses straight square cuts on the same timber sections. The structural strength and all other options are the same across both models.

Fifty-one sizes are listed, from 1.8m deep by 1.8m wide up to 3m deep by 7.8m wide. Depth is the measurement from the house wall to the outermost post, width is how far the structure runs along the wall. Bespoke footprints are available for dimensions between or beyond the listed range.

A sound, load-bearing house wall — solid brick, blockwork or rendered block all work. The wall plate is secured to the wall first, then the outer posts go in using bolt-down feet or concrete depending on the ground. Wall fixings are included in the structure.

When a roof kit is selected, a five degree pitch is built into the frame.

Not for its core protection. The pressure treatment inside the wood handles rot and fungal decay for years without attention. What does fade is the surface stain, and that is worth reapplying every two to three years to keep the finish looking consistent. The stain is the cosmetic layer — the treatment is what holds the structure together.
