Design and Construction System for Commercial Building

Design and Construction System for Hospital & Clinic

We explain about design and construction system for Commercial Building before explaining design flow.

The above diagram shows the system for designing and constructing a Commercial Building.

The client should request the design to Himematsu Architecture, and construction to a construction company.

Although the design supervision contract and the construction contract are separate, our company and the construction company will work together as a team to complete the work until the end, so the burden on the client does not increase.


We will select a local construction company near the site when the design is completed .

You may introduce a construction company with which you have a relationship.

​We highly recommend a local construction company for construction because it takes care of your defects and maintenance after construction.

Upon entering the construction, we will supervise the construction and confirm that it is being carried out according to the drawing. If it is wrong, we point it out and correct it.

Since the construction checking system works, you can safely complete the building.
