  This paper proposes a methodology for the automated construction of
rectangular floorplans (RFPs) while addressing dimensional constraints and
adjacency relations. Here, adjacency relations are taken in the form of a
dimensionless rectangular arrangement (RA) ensuring the existence of a RFP,
while dimensional constraints are given in terms of minimum width and aspect
ratio range for each room. A linear optimization model is then presented to
obtain a feasible dimensioned RFP for user-defined constraints. A GUI is also
developed for the automated generation of RFPs. The proposed model is able to
generate feasible solutions for every possible RA in a reasonable amount of
time. From the architectural perspective, this work can be seen as a
re-generation of well-known architectural plans with modified dimensions. In
the end, the regeneration of existing legacy RFPs (corresponding to the
user-defined dimensions) has been demonstrated, taking their image as input.
