Shelter assembly

An underground shelter assembly for accommodating a small group of people, the shelter assembly comprising:

• a generally cylindrical body with a hollow internal space for accommodating the small group of people, the cylindrical body being adapted to be positioned underground;
• an access passage extending into the internal space of the cylindrical body through an entrance of the cylindrical body to allow one or more people to enter the internal space of the cylindrical body, the access passage being defined by one or more passage walls extending transversely relative to a longitudinal axis of the cylindrical body towards ground level during use to terminate in an access opening;
• wherein the internal space of the cylindrical body comprises a flat floor extending along a length of the cylindrical body, the floor being flanked by welded seating platforms on one or both lateral sides of the floor;
• wherein the floor and the one or both platforms are welded to the inner walls together to define the hollow internal space thereby reinforcing the cylindrical body for resisting the collapsing of the walls of the cylindrical body in a radially inward direction.
