What is a common feature of irregular grid systems in building design?

A common feature of irregular grid systems in building design is indeed indicative of various practical and aesthetic considerations unique to such layouts. Irregular grid systems often result in varying floor thicknesses because they adapt to the specific structural needs and functional requirements of different spaces within the building. These systems allow for greater flexibility in design, accommodating non-standard layouts, varying ceiling heights, and diverse load-bearing needs.

In contrast, minimal floor thickness is favored in many contemporary practices, particularly in structures that seek efficiency and minimize material usage. This approach is essential in irregular grids, as it can help distribute the load more effectively across various points, providing the structural integrity needed for unique designs.

The other potential choices do not align with the nature of irregular grid systems. Heavy reliance on masonry is more characteristic of traditional or uniform structural systems, which may not exhibit the varied typologies found in an irregular grid system. Uniform space planning would contradict the very essence of irregular grids, which thrive on non-uniform arrangements. Use of cantilevers can be found in various designs but is not a defining feature of irregular grid systems specifically, as it relates more to architectural style and intended aesthetic rather than the pattern of spatial organization.
