Development concept of this project

A lively area that makes you want to walk around downtown Miyazaki

The former NTT telephone exchange, located in the city center near Miyazaki Station, will be transformed into a lively hub of activity, with commercial facilities that are fun to walk around and offices that will energize the city.

Plan Overview

North building (Takachiho Street side)

The building has been rooted in the local community for many years as the Miyazaki branch of NTT West Japan, and while retaining its history and stately feel, it will be renovated to create a new opening that opens it up to the town.

The second and third floors will feature approximately 1,150m2 of office space per floor, a rarity in the surrounding area, with a diverse layout design that will enable new and flexible working styles. The building will also feature a piloti space directly connected to the office entrance and a rooftop terrace exclusively for tenants, providing a space for workers to relax and unwind.

The first floor is planned to be a high-quality commercial space that will add color to the daily lives of workers and visitors, with up to six stores planned.
