TS 734

TS 734 is a standard concerned with the definitions used for classifying building and space elements and for dimensioning them. In practical design and documentation work, this kind of terminology standard gives architects, engineers, and draughting teams a common language for describing building parts, spaces, and their size relationships.

How the terminology is organised

From a general technical perspective, classification means grouping elements by function, position, or dimensional relationship. Walls, floors, openings, circulation areas, and rooms have different geometric and planning roles, so consistent definitions matter when drawings, specifications, and calculations need to match. The focus of TS 734 is on the descriptive framework around these elements: how they are named and how dimensioning-related concepts are understood.

Why dimensioning terms matter in practice

Dimensioning is not only about a numerical size; it also involves the measurement conventions used in design and construction. In building practice, clear distinctions between concepts such as clear size, overall size, axis lines, and openings help improve drawing clarity and coordination between components. This standard frames the definitions and classification logic associated with dimensioning rather than prescribing a building method itself.

• Provides a common terminology for classifying building and space elements.
• Supports consistent use of dimension-related definitions.
• Helps improve clarity in design drawings and technical documents.
• Applies to the general language of building measurement and element description.
