OSAKA Midosuji Daibiru Building Reconstruction Plan
An office building that offers new value
to meet the needs of today
Overview of the Midosuji Daibiru Building Reconstruction Plan
The old Midosuji Daibiru Building, which was completed in 1964 and had eight aboveground and three underground floors, was the Company’s first property acquired. The exterior consisted of mainly stainless-steel unit panels and curtain walls that blended well with ginkgo tree-lined Midosuji Avenue. The building, which received the 7th BCS Prize in 1966, was an essential part of Osaka’s urban landscape, well-suited to the city’s cosmopolitan character.
Nearly a half-century after its completion, the building was suffering from aging and declining competitiveness compared to surrounding buildings, and in 2018, we announced a redevelopment plan. To maintain the affection held for the original building, we preserved the Midosuji Daibiru Building name.

Details
Redevelopment aimed at revitalizing
the business district

Our plan to redevelop the Midosuji Daibiru Building was announced in 2018, before the COVID-19 pandemic. More than 50 years since its completion, the building’s core facilities were aging, and it had become less competitive than newer properties in terms of room configuration and ceiling height.
The Honmachi area, where the building is located, was facing a decline in status, and many large companies that previously had offices there were moving to Umeda, near Osaka Station.Still, there was strong demand from IT, consulting, construction, and interior design companies, and we wanted to revitalize the Honmachi area by rebuilding Midosuji Daibiru Building, which meant it needed to set the standard for the next generation of office buildings.

Delivering office value that remote work simply can’t achieve
The former Midosuji Daibiru Building closed in December 2020, marking the official start of the redevelopment project. This was during a period of significant social upheaval, marked by states of emergency due to the COVID-19 pandemic, which led to notable changes in how people work and the role of the office.
As work style reforms took root and remote work became widespread, we reexamined the value that office buildings should provide in this new era. We concluded that our 2018 vision of creating a building suited for diverse workspaces and working styles remains relevant in the post-pandemic era, with a new emphasis on delivering value that remote work cannot provide.
This led to the concept of “Your Premium, Your Workplace.” To develop this concept and unify our vision, we held workshops with the sales team, who regularly interact with tenants and are attuned to their needs, alongside the technical and development teams, who are focused on solving new design and construction challenges.

Boosting employee wellness

An office building for the modern era: prioritizing health and environmental sustainability
The office remains essential for fostering teamwork and developing talent through daily interactions and for driving creativity through collaboration across departments and fields, which has led to a growing awareness of the unique value that the office provides. The new Midosuji Daibiru Building, completed in January 2024, was designed to meet these needs. The second floor features a variety of spaces, including a tenant-exclusive lounge, to facilitate communication, relaxation, and activity-based working (ABW), and the fourth floor has been dedicated to our first co-working office, “ouno.”
To address the growing emphasis on both the physical and mental health of employees, we have added “wellness staircases” filled with natural light to encourage walking, as well as “refreshment terraces” that allow people to get some fresh air and reset mentally. To connect with the greenery along Midosuji, we’ve added indoor and outdoor landscaping on the first and second floors, reflecting our commitment to environmental sustainability and harmony with nature.
The metal facade, reminiscent of the previous building, reflects the bustle of people walking down the street.
The building has been a pillar of the city’s growth and a mirror of its vibrancy, and we are committed to further elevating its value.


“ouno” dedicated shared office space floor, a first for Daibiru
The fourth floor, known as “ouno Midosuji,” is dedicated to shared office space and provides a premium workspace that includes private rooms for small groups and a lounge area with luxury furniture. Under the concept of creating a premium space for each and every individual, “ouno” offers the best (i.e., premium) environment to every worker with sophisticated designs and services. In a time when working styles are becoming increasingly diverse, “ouno” represents a new proposal from the Company created to accommodate modern work situations.

Achieving full occupancy through attentive service
Enhancing satisfaction through a unified system
Handling everything from securing tenants to helping them move in, our sales team also plays a key role in building development and launch, which is a hallmark of our sales strategy.
I believe that we were able to achieve full occupancy at completion due to this integrated strategy, and it has been rewarding to see how much our tenants enjoy being here. (K.I.)
What it means to be a developer
We made various creative choices, such as arranging greenery from the first-floor entrance to the second-floor terrace to bring a sense of nature both indoors and out. I believe this captures our company’s enduring philosophy of being in harmony with nature.
This project has reminded me of what it means to be a developer—creating vibrant buildings and lively communities. (R.T.)

Designing a clean and inviting space
Always keeping the customer’s perspective in mind
As a member of the Daibiru Group, I strive to create a clean and comfortable environment.
Office buildings see a lot of foot traffic, and I strive to maintain Daibiru’s reputation for having consistently spotless buildings, which helps people build a stronger connection with the building.
I felt grateful when a customer noticed my name tag, saw that I was from the Philippines, and offered encouragement, understanding how challenging it can be to adjust to a new country and environment. My goal is not just to gain certification as a third-class building cleaning technician but also to improve my Japanese to better communicate with everyone. I’m focused on enhancing my cleaning skills and staying motivated to do my best. (М.A.)
