Space Design Architects Co., Ltd.
Beautiful space for you to feel at ease
We understand designing a space to mean imbuing it with beauty and life.
Here at Space Design Architects Co., Ltd., we aim to bring not just beauty and life to each and every space we design, but also careful consideration for its inhabitants through providing healthy indoor air quality.
As a team dedicated to creating such architecture, we look forward to actively responding to your requests and inquiries.
To address structural changes in society due to Japan’s aging population, the Building Standard Law, Medical Care Law, and numerous other regulations have been revised in recent years. Along with this, we see an increasing need to revisit the architectural design of residences and facilities.
By now, we can all say that in Japan, disaster preparedness is a must. Through our seismic diagnosis and earthquake retrofitting work, we can help deliver peace of mind for you should such a day come. Considering various methods, we will propose a plan that takes into account not only performance and cost, but also design.
Surveys, Inspections, and Periodic Reports
In principle, we offer free consultation on the various aspects of architecture to those who visit our offers. We can offer this advice objectively not as a contractor, but as a third party, so please feel free to visit us.
We supervise construction to ensure building safety. From the owner’s perspective, the project’s quality and value are ensured through our careful management of the construction process.
Through attractive outdoor design including architectural illumination, we can improve a facility’s surroundings.
Addressing Sick Building Syndrome
We are making efforts against “sick building syndrome” caused the off-gassing of pollutants from building materials.
We will break down and explain fees for consultation, schematic design, drafting construction documents, and performing construction management.
