Two person work environment

A space dividing assembly including at least a first top member having first and second substantially parallel and oppositely facing lateral edges, a top surface and an undersurface, at least a first bottom member having first and second substantially parallel and oppositely facing lateral edges and a top surface, the bottom member having a shape that is substantially similar to the shape of the top member and spaced there below so that the first and second lateral edges of the bottom member and the first and second lateral edges of the top member are substantially vertically aligned and so that the facing top member undersurface and bottom member top surface form a space there between and at least a first internal wall member having a length dimension and disposed in the space between the top and bottom members with the length dimension substantially parallel to the first lateral edge of the top member and with the internal wall member spaced apart from the first and second lateral edges and closer to the first lateral edge than to the second lateral edge, the internal wall extending between the undersurface of the top member and the top surface of the bottom member so that the internal wall member divides at least a portion of the space between the top and bottom members into a first shelf space accessible from adjacent the first lateral edge of the top member and a second shelf space accessible from adjacent the second lateral edge of the top member.
