More About Sreed Ebisu T Office Building

Sreed Ebisu T is a nine story office building in Ebisu, Shibuya ward, Tokyo. The building uses a hybrid structure that combines a steel post and beam frame with timber seismic frames inserted into it. The timber frame, named the seismic timber lattice shell, serves as both a structural and an interior element. Members that resist only seismic force do not require fireproofing, so the timber remains exposed. The lower floors hold restaurants or retail stores, and the upper floors hold offices. Common terraces along the staircase support breaks and interaction.

About Salhaus

Motoki Yasuhara is a Japanese architect and associate professor at the University of Tokyo. After working for nine years at the office of Riken Yamamoto, a 2024 Pritzker Prize laureate, he co-founded the architect office SALHAUS in Tokyo with Masashi Hino and Mari Tochizawa. Since then, he has received high praise for the many timber public buildings with local timber. In recent years, he has also realized several high-profile projects involving mixed-use urban architecture, including urban timber buildings.

Award Record

Salhaus is a winner of 1 A' Design Award, including this recognition.

Design Details

Unique Properties
This project is a nine-story office building in Tokyo. We tried to create a new prototype for urban timber architecture in this project. Our proposal was a hybrid structure of a steel post-and-beam frame and timber seismic frames inserted into it. This timber frame, which we call a "seismic timber lattice shell," is not only a structural but also an interior element to realize new workspaces where people can work in a more relaxed mode, enjoying the spatial value of the timber construction.
Inspiration
The design of this building was carried out during the COVID-19 pandemic. People stayed home; some even said office buildings were no longer necessary. In this project, we considered what kind of workspace would be worth visiting and working in even after online working technology was established. Our answer was architecture, which provides the comfort of a home and maximizes the value of working together.
Research
Two primary motivations for promoting the construction of timber buildings in Japan today are, reducing CO2 emissions during construction and making use of the vast forest stock. Structural strength and fire resistance are the main issues when employing timber for urban buildings. We developed a method of using timber as a seismic element to brace steel frames, which can also work as an exposed interior element; structural members that only act against seismic force do not require fireproofing.
Challenge
As this was an unprecedented construction method, we put great effort into the detailed design of the steel and timber joints. During the construction phase, we formed a team with a contractor, a steel fabricator, and a timber fabricator, both with high technical capabilities, and worked out the details of the joints while sharing 3D data. In addition, there were differences in the production accuracy between the two fabricators, so we paid close attention to the accuracy management on site.
Realization and Technology
Urban timber architectures, which have recently been booming in Japan, are dominated by multi-story buildings with post-and-beam frames that have acquired special fire-resistance certification. However, these buildings simply replace RC or steel-frame construction with timber and do not possess the spatiality unique to timber construction. Our goal was to create a new typology of urban timber architectures that maximizes the spatial value of timber construction and allows end users to enjoy the value.
Operation and Interaction
In addition to creating an intimate workspace wrapped in timber on each floor, we created rich common spaces to facilitate workers' interaction. We designed a staircase not only as a simple evacuation route but also as a daily traffic route and arranged many common terraces along it. Taking a break outdoors or communicating with people from other companies will activate collaboration and creativity among workers.
Project Duration and Location
This building's site is located in Ebisu, Shibuya-ward, Tokyo. We designed the building from June 2020 to June 2021, and construction work was carried out from June 2021 to January 2023. The building was put into use immediately after that, and all floors are currently rented out to tenants.
Specifications
This project is a 9-story, 34.3m-high rental building with a total floor area of 564.7m2 and a footprint of 80.0m2. The ground and first floors are for restaurants or retail stores, and the third to ninth floors are for offices. It has an evacuation staircase and an evacuation balcony on each floor required by law, and an elevator. In addition, it is a fireproof building under the Building Standards Act.
