Terraform Deck, Large

3.0 × 3.0 m · 9.00 m² · a complete deck, delivered to your door.

A proper outdoor room. Nine square metres, three bearers, and still no concrete slab. It arrives flat-packed on a pallet and goes down in an afternoon.

What's in the box

• 3 × aluminium bearers, cut to 3.0 m
• 16 × aluminium joists, cut to 1.445 m
• 8 edge brackets and 24 centre brackets, pre-punched to hold the spacing
• Adjustable pedestal feet
• Decking boards, clips and edge trim
• 256 galvanised hex screws, counted
• Printed instructions, parts checklist and a link to the full build video

What you bring

An 18 V drill, a hammer, a tape measure, gloves, and eye and ear protection. Nothing gets cut, so there is no saw on the list. Two people recommended at this size.

Why aluminium

The frame is the part of a deck that rots, sags, burns and gets eaten. Ours is extruded aluminium 6005-T6, so none of that happens. Under 3 kg per metre, so a full bearer goes over one shoulder. Termite proof, rot proof, non-combustible, and it never needs a coat of anything.

Kits bolt to kits, so two Larges make a 6.0 × 3.0 m deck. Foundations must be prepared to local requirements; permits and footing certification are the installer's responsibility.
