Free height of main and auxiliary space

Question:

So, what’s the deal with the free height of the main use space: is it 2.40 m according to building regulations or 2.65 m according to the Building Code?

Answer:

The building regulations state in paragraph 1: The minimum permissible clear heights of building spaces are defined as follows: 1.1.1. For primary use 2.40 m.
N.O.K. Article 2, paragraph 95. The main use spaces of buildings are those intended to serve the basic use of the building and the stay of its users in them, 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 most recent law prevails over the building code.

Question:

Does Article 8, §2.1 of the Building Regulations still apply in conjunction with the provisions of Law 4067/2012 on free height?

Answer:

Yes, it still applies and specifies how to measure the actual free height, as does the section of the same article of the Building Regulations that specifies the free height of auxiliary space as at least 2.20 m (see the issue of technical instructions from the Ministry of Environment, Energy and Climate Change for the implementation of the Building Regulations, Article 2 §95 and §96).
