What We Do

Service Overview

In recent years, the Japanese residential properties are increasingly popular among foreigners.
These people are not only those who have been posted in Japan, but they also include many who have been attracted to the values of Japanese real estate properties.
However, communication proves to be a difficulty in search of a property in Japan. We have received consultations from developers as well as real estate agencies regarding the difficulty to find the right design company capable of understanding and meeting requests for specific layouts of rooms and special interior design due to the language barrier.
ONE DESIGNS offers services to our customers with our expert knowledge in English.
Although Japanese apartment have many building restrictions with renovations, with ONE DESIGNS experience and expertise , we can meet your requests involving the reconstruction of the building from skeleton.
ONE DESIGNS provides the highest quality workmanship and service to our clients.
