This paper applies network theory to understand the physical relationships in the general arrangements generated by TU Delft packing approach. The generated arrangements are converted into weighted graph networks. The authors have developed a new scoring metric using this network and have applied this to quantitatively assess qualitative properties of the different arrangements, enabling direct comparison between concept designs. Finding and understanding these specific physical properties of the arrangements should lead to improved design space exploration of layout features of the designs generated by the TU Delft packing approach.
