Hibiya Engineering — Grand Park Tower: talk to change, act to grow

Hibiya Engineering designs and installs air-conditioning, plumbing, electrical and communications systems. Its Tokyo head branch on the 31st floor of Grand Park Tower had kept almost the same fit-out for over 25 years. A 17-member team drawn from every department rebuilt the 2,048 m² floor for about 400 people with UCHIDA YOKO, under project management by NTT Facilities.

Concept

People and information

Fixed island desks had left some islands crowded and others empty, and meeting rooms were so scarce that some staff worked from home just to join online meetings.

UCHIDA YOKO proposed “an office where people connect with people and information and move towards the future”, chosen by the project team and a staff vote.

01 · Parks

Communication parks and hybrid rooms

In an open group-address work area there are two communication parks and two hybrid meeting rooms for any department or group size. Near the guest area are a coworking lounge and a library studio that connect with other sites and customers.

Screens everywhere

Monitors at every meeting spot sped up the move to paperless work, while shared paper documents such as specifications were consolidated.
