Computer-Aided Architectural Plan Generation: 2D Mesh Segmentation, Search Optimisation, and Clustering for Generating Plans
In the architectural design, segmenting given floorplates into spatial partitions and subsequently deriving arrangements of architectural elements (such as walls, furniture, and entries, etc.) to form the so-called architectural plans is a complex problem. Each spatial configuration involves various constraints and variables (such as unit types, areas, and orientation) that need to be balanced. Architectural plans represent the core ideas and solutions in architectural communication. However, in practice, resolving architectural plan solutions and managing the solutions into one plan takes a significant amount of effort during the phase of schematic design. This is because the solution of spatial allocation cannot easily be procedurally derived, and the problems and constraints of the task are often ill-defined. Typically, the solution evolves over several iterations. This process requires larger numbers of solutions to be made. To address these issues, a systematic method is demanded.
This thesis interrogates a computer-aided architectural plan generation method using a parallel graph-search algorithm in combination with an evolutionary optimisation algorithm. This research tests architectural plan generations in residential design, particularly targeting the typology of the residential tower in the case study.
The aspect of the graph edge provides a way to measure the formation of the unit from the grid. This aspect will help to identify the unit types and categorise the given shapes.
This figure illustrates the architectural elements of two units as examples in order to demonstrate the correlation between the floor plan, units, and architectural elements (seed: 577).
The generator will output different spatial configurations that can fit different unit types according to the design agenda and changing area requirements. This algorithm can also be applied to situations where floor plans are rotating, like that of the Absolute Towers.
