The study or science of the structure and design of buildings and other physical forms, often related to architecture and philosophy.
The architectonics of the new museum were praised for their innovative design.
Architectonics is formed from "archi-" (from Greek "architekton", meaning chief or master builder) and "tectonics" (from Greek "tektonikos", meaning pertaining to building or construction). The word refers to the art and science of architecture and the structural design of buildings.
Think of a 'master builder' ('archi-') who is skilled in 'building' ('tectonics') — that's why architectonics relates to the design and structure of buildings.
