Softwood Decking, heavy duty pressure treated timber deck boards screwed to a solid pressure treated timber frame.
If you already have a design for the deck, i.e. shape of deck, differing levels, stair positioning and board directions, then simple instruction on these details are all the installation team will need.
Would you like the platform to finish flush with existing ground levels? For example grassed areas, patios, swimming pools, etc, some excavation may be required.
Is the platform higher than the standard step up of 6 inches? Does it have open edges? Then balustrades (handrails) are required for safety.
If the platform is higher than just the standard step up of 6 inches a Skirting is recommended for aesthetics. The first 6 inches are included and referred to as the fascia board from which the Skirt continues down to ground level.
