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.

We are Kichi Architectural Design based in Japan.
The design of homes is our main business line, but we also design HOTEL,chapel,
stores and offices.
While appreciating the inherent energy of land, we cultivate expansive ideas through repeated consultations with each client.
Our aim is to create unique spaces that resonate with the spirits of the people who will live there.
