To evolve into a company that will last 100 years for the next 50 years
– Aspirations and beliefs for heights, and its pride as an expert in shaping buildings and towns –
ACA SEKKEI celebrated its 50th anniversary in July 2020. Since its founding in 1970, it has always inherited the stance of taking on challenges. With awareness and pride as a group of architectural design specialists, we have contributed widely to society through our design activities, aiming for attractive architecture that is trusted and pleased by our clients.
We will respond to the changing sophistication and complexity of society, pursue new technologies with aiming for highly worth design work. We will pursue “architecture in the environment” that is harmonized with the natural environment and local communities and create architecture that contributes to the creation of a sustainable society.
As construction demand is declining due to today’s declining birthrate and aging society, we will focus on already opened bases in Southeast Asia, where development is expected in domestic local cities and future development, and always challenge undeveloped areas with foresight. We will continue to develop and grow into a company that can meet all social needs and create new value to further refine and evolve our efforts so far and make a further leap forward in the next 50 years.
