River City 21 East Towers

1991, exactly 30 years ago. River City 21 East Towers is a pioneer of Tokyo waterfront development and was completed as a prototype of a tower-type high-rise condominium that emphasizes the view.

The location is in Tsukuda 2-chome, Chuo-ku, and although the nearest station is Tsukishima Station, it is an excellent location environment with smooth access from Tokyo Station and Ginza Station, and is an area with a diverse range of tenants.
In the Edo period, it was also called Ishikawajima, and you can feel the history of the Showa era everywhere, such as the food culture unique to Tsukishima and the shopping streets with the downtown atmosphere in the modern townscape, and a unique culture has been formed even in Tokyo.

This project was planned for the purpose of large-scale renovation of a group of condominiums (four buildings), including public vacant lots, acceptance of new tenants, and new increase in asset value.

[Solution]
In addressing our clients' challenges, we developed a new concept called "1.5 Place," which involves creating a second place function and a third place time around their first place, their home. We also confirmed that there was no discrepancy between the functions and concept design direction of the newly created rooms and spaces through the implementation and analysis of surveys conducted with residents.

In particular, in response to the needs of residents, which became clear from the survey analysis, we not only improved the functionality of the entrance, meeting rooms, and lounges, but also planned co-working spaces and places where communication could be fostered, anticipating diverse ways of living, working, and gathering. As a result, we created a "highly social and altruistic space" and a "space whose value increases over time," leading to increased resident satisfaction and the creation of new attractions.

Furthermore, we also proposed solutions from an SDG perspective, not only addressing the generally accepted solutions for sustainable economic and social conditions, but also understanding the local context and user perspective of this project. By considering factors that influence the living environment, such as tradition, culture, and local characteristics, we imbued concept design concept and materials with meaning, realizing a form that is appropriate for this property.
In realizing these solutions, our company ensured that each section worked together seamlessly, effectively utilizing design, layout planning, research, implementation, and construction capabilities to respond quickly and accurately to customer requests.
