Tsukuru Jisho Completes Registration as a First-Class Architectural Office

Tsukuru Jisho Co., Ltd. (Headquarters: Minato-ku, Tokyo) has announced that it has completed its registration as a First-Class Architectural Office.

With the mission to "Create land, create towns, create together," the company has been redesigning real estate development using digital technology. With this registration, the company, which already holds a specific construction permit, now encompasses business planning, construction, as well as design and construction supervision capabilities. Moving forward, the company will offer a wider range of options to assemble optimal project structures for each case, enabling real estate investors and developers to make highly effective investment and development decisions from conception to execution.

Yuichi Kaneko, who holds certifications as a First-Class Architect, First-Class Construction Management Engineer, and Real Estate Notary, has been appointed as the chief architect of the First-Class Architectural Office. The company will promote its design and construction supervision system with the chief architect at its core, supported by a team of multiple specialized personnel.

Two Key Industry Challenges

Challenge 1: Fragmentation between processes In real estate development, planning, design, and construction are often conducted by different entities, leading to fragmentation where initial business policies are not fully reflected in design, or construction risks are not fed back into business plans.

Challenge 2: Lack of flexibility due to standardized structures The optimal framework for development projects varies by scale, usage, and client. It is crucial to have the flexibility to select necessary functions and assemble optimal frameworks for each project rather than relying on a standardized approach.

As a company that designs the "framework" rather than just the "process" of development, Tsukuru Jisho possesses planning, design, construction supervision, and construction functions internally, working with clients to ensure land projects are viable as businesses.

Service Structure

Tsukuru Jisho possesses three internal functions: "Planning," "Design & Construction Supervision," and "Construction," which are combined flexibly based on project characteristics.

▼ Three Functions 1. Planning: Handling development planning and business promotion based on AI-powered land analysis. 2. Design & Construction Supervision: Handling design and construction supervision as a First-Class Architectural Office. 3. Construction: Handling the construction phase as a primary contractor or construction management (CM) representative based on its specific construction permit.

▼ Three Frameworks Based on Project Characteristics - CM Representative Type: Handles design, construction supervision, and CM for projects where the client is the project owner. - Prime Contractor Type: Undertakes construction as a licensed specific construction contractor for projects where assuming construction risk is effective. - Design Supervision Type: Handles design quality assurance and business integration for projects where the client's existing structure is to be respected.
