If we draw a graph where each vertex is a room (one vertex for the outside) and draw edges for doors, we'll find that the question is to draw an Eulerian path.
The prerequisites of such a path is that there will be no more than 2 vertexes with odd edges. In this case A,C,B and 'Outside' have Odd number of edges.
Therefore adding an edge A-C will leave only 2 vertexes with Odd edges and produce an Eulerian path.
To connect A and C I would probably build the shed on a cone surface so A and C.
