Structural assembly and method of assembly thereof

A method for assembling a first cardboard assembly member to a second cardboard assembly member, the method comprising:

• providing a first cardboard assembly member having two or more pairs of first, elongated connector elements fixed thereto or integral therewith, wherein each of the first connector elements:
• extending along a first axis, all first axes of the connector elements being parallel to one another,
• having one or more recesses extending along a second axis normal to the first axis, each recess in one of a pair of first connector elements being aligned with a recess in the other of said pair,
• projecting from a face of said first assembly member, and
• being made of wood, cardboard or plastic;
• inserting the first connector elements into the second cardboard assembly member;
• and
• inserting a plurality of second connector elements, each being made of wood, cardboard or plastic, into the second assembly member along said second axis so as to be received within a corresponding pair of aligned recesses of a pair of the first connector elements to thereby lock the first connector element in position and prevent detachment between the first assembly member and the second assembly member.
