HS = lean-to design; LV = centrally vented design
The list above shows only the amounts used and approximate sizes of timber within the structure. It does not include concrete boxing, pegs and other general building requirements, e.g. offcuts.
In practice a further 15-20% more will be needed.
Drying trays: See elsewhere for material ideas.
Cement: The retaining walls as described will require 32-36 bags (40kg).
