Voronoi Diagrams-Based Floor Plans Design Method

Designing floor layouts is a crucial aspect of architectural planning. Typically, several types of layout plans are prepared before any actual construction begins: site plans, section plans, floor plans, and elevation plans.

These 2D designs not only serve as blueprints for building but also help architects visualize and communicate their unique concepts. However, manually creating these layouts can be time-consuming and requires considerable skill, especially given the varied shapes of spaces and the specific requirements for room sizes and connectivity. These challenges can discourage architects from freely exploring innovative design ideas.

To address this issue, researchers have developed many computational algorithms to aid in generating floor layouts. What you see in the image above is the algorithm developed for Xuanyu Wu, Kenji Tojo and Nobuyuki Umetani's paper, Free-form Floor Plan Design using Differentiable Voronoi Diagram.

The paper presents an innovative shape representation and optimization technique for designing floor plans using Voronoi diagrams. The Voronoi diagram implicitly defines room shapes according to distances from Voronoi sites, allowing for topological changes in the wall layout by adjusting these sites. With easy differentiation of the explicit wall representation, this method can incorporate various constraints, such as room areas and connectivity, into the optimization process. The researchers demonstrate that their approach can generate a variety of floor plans while enabling users to interactively modify the constraints.
