Building Primitives

Building primitives let ArchAI create complete building options, not only edit individual walls.

Whole-Building Concepts

Concept	Purpose
Building	Top-level authored building
Building part	Wing, podium, tower, annex, or phase
Massing volume	High-level volume before detailed elements
Floor plate	Level footprint and planning boundary
Structural grid	Repeating structural coordination system
Core	Vertical circulation and service center
Circulation	Corridors, lobbies, paths, ramps
Unit	Apartment, office suite, hotel room, or other program unit
Program block	Allocated use/area target
Facade system	Envelope/facade strategy
Roof system	Roof shape and assembly
Vertical shaft	MEP/service vertical continuity
Service zone	Horizontal or vertical service allocation
Parking layout	Site/building parking arrangement
