In all the designs we applied the golden rule of analogy used by the ancient Greeks for the construction of their temples. For instance this rule was used for the construction of Parthenon and the temple of Zeus in Olympia.

In the construction of all the houses we used also parian marble stones.This marble is extremely fine - grained and almost transparent. It was used to build some of the most important monuments of the classic period such as, Ermis of Praxitelis, Niki of Samothrakis, and the forefront of the temple of Delphi. For house constructions the golden rule is applied on the width and length of rooms based on the 2 to 1 analogy.

Which leads us to the golden number Ö=1,1618 and to the golden mean.

This number is the golden number Ö connected with the ancient holy number 5. Ö is applied on the rooms analogies and gives unique beauty and properties to the space.

It maybe useful to remind that the golden mean is the number which if it's increased or decreased by 1 it becomes equal to it's opposite.

Therefore there are two golden means which are the positive square roots of the previous equation. The two square roots are equal to

Ö1=1,618 and Ö2=0,618.
