Tsukuru Jisho Completes Registration as a First-Class Architectural Firm

Tsukuru Jisho Co., Ltd., based in Minato-ku, Tokyo, has recently announced the completion of its registration as a first-class architectural firm. This development is a significant milestone for the company, which operates under the mission of "Creating land, creating communities, creating together."

The registration enables Tsukuru Jisho, which already holds a specific construction business permit, to enhance its services by adding design and construction management capabilities. This allows the company to offer comprehensive support to real estate investors and developers, providing wide-ranging options for effective investment and development decisions from the conceptual phase through to execution.

About the New Management Architect

The chief management architect for the newly registered firm is Yuichi Kaneko, a holder of three key qualifications: first-class architect, first-class construction management engineer, and licensed real estate transaction manager. The company will build a team centered around Kaneko, utilizing various specialized professionals in its design and construction management efforts.

Addressing Industry Challenges

The real estate development industry faces two primary challenges:

1. Fragmentation Between Phases: Often, the design, planning, and construction phases are managed by different entities. As a result, initial business policies may not translate effectively into the design stage, leading to construction risks that are not communicated back into the original planning phase. This disconnect can hinder project effectiveness.

2. Lack of Flexibility in Standardized Systems: Each development project is unique, depending on its scale, use, and client needs. When a rigid system is applied, the ability to select necessary functions and create optimal configurations for each project is compromised. Tsukuru Jisho aims to overcome these hurdles by designing solutions that focus on the 'structure' rather than just the 'process' of development.

Our Service Structure

Tsukuru Jisho organizes its operations around three essential functions—planning, design, and construction management—which can be flexibly combined according to the project's characteristics.

1. Planning Function: At the core of this function is land analysis and business forecasting aided by AI, driving the development plans forward.
2. Design and Construction Management Function: As a newly registered first-class architectural firm, Tsukuru Jisho is now equipped to manage design and construction oversight.
3. Construction Function: Operating under a specific construction business permit, the firm can undertake construction as either a general contractor or as a construction manager (CM), overseeing projects on behalf of clients.

Tailored Operational Structures

Through the Construction Management model as the primary focus, Tsukuru Jisho provides three distinct approaches based on project characteristics:

• - CM Model (Primary): For projects where the client is the contract owner, Tsukuru Jisho takes on the roles of design, construction management, and oversight.
• - General Contracting Model: For projects where assuming construction risk is beneficial, the company acts as the main contractor.
• - Design Supervision Model: In cases where respecting existing client structures is paramount, Tsukuru Jisho ensures design quality and alignment with project objectives.

In addition, the company is committed to redesigning the overarching real estate development industry through the establishment of digital infrastructures that connect planning, design, and construction, enhancing efficiency and outcomes.
