Modular wall unit

A modular wall unit for a modular wall system, the modular wall unit comprising:

• A) a body having:
• first and second outer wall faces;
• first and second joining faces that each extend between the first and second outer wall faces;
• at least one of the first and second joining faces for facing a joining face of a further modular wall unit of the modular wall system;
• a first through-hole extending between the first and second joining faces;
• B) a first elongate reinforcement member:
• extending between the first joining face and the second joining face and within the first through hole;
• having at least one tubular portion proximal to a terminating end of the first elongate reinforcement member,
• wherein the modular wall unit is configured such that:
• the body further comprises an internal recess extending away from and adjoining the first through hole;
• the modular wall unit further comprising an internal recess elongate reinforcement member that:
• resides in the internal recess;
• and
• is connected to the first elongate reinforcement member;
• wherein the modular wall unit further comprises one or more support members extending outwardly from the first or second outer wall face;
• and
• wherein the one or more support members comprises a first support member extending from the first elongate reinforcement member.
