From Engineer to Owner: The Journey of Khun Khajee Ketsumpol
With over 30 years of experience as a professional builder, Khun Khajee Ketsumpol, founder of Nai Chang Thai Construction Company, has dedicated his life to the art of home building. Renowned for his craftsmanship and deep understanding of construction, he decided it was time to create something of his own — homes built with heart and imagination — under the name HACHI Brand.
For Khun Khajee, every building is more than just a structure; it is a piece of art waiting for its true owner. With his hands-on expertise and passion, each HACHI home comes to life through thoughtful design and masterful execution.
“We are builders at heart. Building homes is our happiness.”
The story of HACHI began with inspiration and passion.
After decades as a contractor, always following other developers’ visions, Khun Khajee decided to step into a new chapter — becoming a property developer himself. With experience, skill, and strong connections in the industry, he envisioned creating homes that reflect his own artistic vision and identity.
This led to the birth of HACHI — a brand built on passion, creativity, and craftsmanship. Every HACHI home is a one-of-a-kind creation, built not just for living, but as an expression of art and happiness.
His dedication and excellence have even earned international recognition, including awards for architectural design on the global stage.
At HACHI, each project begins from a piece of empty land and a simple idea — to create unique homes that embody freedom, art, and individuality.
Khun Khajee works closely with architects who share his vision, ensuring that no two HACHI homes are ever the same. Every design is distinctive and will never be duplicated again, making each home truly “One of a Kind in the World.”
HACHI’s mission is to turn living spaces into art — supporting architects to express their creativity while redefining what “home” can be.
“A home should not only be a place to live, but a place that inspires warmth, joy, and connection.”
Freedom of thought and creativity lie at the heart of HACHI.
For Khun Khajee, quality speaks through craftsmanship, and every home must truly resonate with its owner’s lifestyle. A HACHI home is designed to be lived in — to feel warm, personal, and full of life.
One of HACHI’s proudest milestones is the SUNONE Building, which earned global recognition at the Merit Award (USA, 2009) — honoring outstanding architectural design in the “Medium Office” category. The project was praised for its harmonious balance between form and environment, preserving the serenity of its residential neighborhood.
