Free height of space main use

Question: What ultimately applies to the free height of the main use space: 2.40 m according to the building code or 2.65 m according to the N.O.K.?

Answer: The building regulations state in paragraph 1: “The minimum permissible clear heights of building spaces are defined as follows: 1.1.1. for main use 2.40 m.

N.O.K. Article 2, paragraph 95. The main areas of use of buildings are those intended for the basic use of the building and the stay of its users, such as bedrooms, living rooms, kitchens, and offices in residential buildings. For buildings constructed after the entry into force of this law, the main areas must have a clear height of at least 2.65 m.

The N.O.K. as the newer one prevails over the building code.
