Development Concepts

The concept for the creation of ARK Hills is "creation of a total environment city", namely a business city that meet the needs of the current era of internationalization and greater use of information technology, a 24 hour multipurpose city complex, a city with a comfortable environment, and an intelligent city. We joined together small plots of land and concentrated buildings into fewer high-rise ones in order to create a rich city space and open spaces overflowing with greenery. Furthermore, we combined eating, living, playing, and all of the other diverse functions necessary in a city in one place to create a compact "city within a city."

Facility Plan

ARK Hills was Japan's first large-scale private redevelopment project and was completed in 1986 after seventeen years of labor. It features a diverse range of functions, including offices, residences, a hotel, and a concert hall, and was the forerunner of all subsequent Hills projects, which are based on the principles of bringing work and residences in closer proximity, promoting the arts, and fostering the coexistence of the city and nature .
The themes of the facility plan are to create a comfortable environment while realizing the high level of functionality expected of a central city area, to be able to maintain the harmony of buildings with different uses within a multipurpose complex while enabling each building to perform its functions as well as possible, and to incorporate advanced technologies.

Architectural and Design Concept

For large-scale comprehensive developments it is important to achieve a balance between consistency with the overall city district and the individuality of each building. We designed the complex so as to maintain the framework of the city and the identity of the town of ARK Hills and at the same time express the individuality of each building that arises from its functions.

History of the Development

ARK Hills was the first large-scale multipurpose redevelopment project undertaken by Mori Building. Way back in 1967 Mori Building acquired its first land in this area and after the government had designed the site as suitable for redevelopment we actually spent nineteen years on the project. It is no exaggeration to say that the urban planning philosophy of Mori Building supported the enormous amount of time and energy we expended on the project.
