From the design, which is the beginning of construction, to the structure, construction, and finally, demolition, the entire building life cycle 
Pine Tree Structural Safety Architecture (Pine Tree Architectural Office, Sonamu) has built unrivaled expertise across various fields. 
Namu A&E) is holding a special exhibition to celebrate its 12th anniversary.

This exhibition, 'Architect Jeong-Hoon Yoon', which will be held in Insa-dong for three days starting December 19, will showcase the beauty of traditional architecture.
This is a record and a site that demonstrates how the precision of modern engineering meets and resonates. 2013
The path that Sonamu Structural Safety Architecture has taken over the past 12 years since its opening in 1998 has been centered around the theme of ‘integration of architecture’.
do.

This exhibition is organized by Jeong-Hoon Yoon, an architect, construction engineer, doctor of engineering, woodworking technician, and master carpenter. 
The exhibition presents three core themes centered around Jang's work. 

First, ';어레' goes beyond a simple tool and shows the aesthetics of architectural structure. Architect Jeong-Hoon Yoon personally designed it.
These ridges are made by carving them with ';gyeolgu', a traditional Korean house custom-made method, and are made without a single nail.
It also boasts sturdiness, and all parts are designed to be assembled and disassembled, following the principles of architectural structure. 
It penetrates.

Second, ';Dohaengji' is a detailed construction drawing with a scale close to 1:1, so that the designer's intention can be accurately conveyed on site without error.
This is a 'map of architecture' that integrates the concepts of plane, section, and elevation to be implemented. 

Third, the ';horror structure' symbolizes the meeting of tradition and cutting-edge technology. It is the core that determines the depth of the Hanok roof.
By recreating the fear element of the heart with 3D printing technology, the general public can intuitively understand the complex structure of Hanok. 
Implemented so that it can be understood. 

Seminars held during the exhibition period deepen these practical achievements academically. Architect Yoon Jeong
Special sessions on Hanok, demolition, and structure led by Chairman Hoon and structural engineer Eun-jin Lee, as well as next-generation 
The lecture on chisel and AI (artificial intelligence) utilization conducted by master carpenter Kim Ga-yeon and master carpenter Yoon Young-chan is unfamiliar. 
This will be a meaningful opportunity for the public to easily understand difficult architectural techniques and share a vision for the future. 

Through this exhibition, Pine Tree Structure Safety Architecture aims to “raise the value of architecture through responsible technology and sincere practice.”
We will go out here", Chairman Yoon Jeong-hoon's philosophy is once again declared. The hands of a master carpenter who carries on the tradition and 
This exhibition, which is presented through the eyes of engineers responsible for structural safety, is a deep experience for those who love architecture. 
It will convey the resonance.
