Why this spec, for gardens where the deck steps up from a lower lawn or falls away over a slope — engineered elevation, not a ground-level lay
- structural posts sized for the elevation and span — not a chippy's guess
- handrails and balustrade built to building-regs height where the drop demands it, without looking like a scaffold
- integrated LED and drainage runs sorted at frame stage, not chased in later
Common failure modes on raised terrace decking
