field energy and
When materialized space does not suit
The local magnetic field collapses
But the space there
If it is successfully merged with its energy ​
​The place creates the best vibration

With the energy of the place and repeated dialogue with the client,
How simple can it be? I asked again and again,
We will do our best to pursue minimal beauty and richness in both life and design.

Healing is allowing yourself to return to your true self.
Architecture is a place where various things are brought together, balanced, and harmonized.
