This is a value-enhancing renovation project for an office building located in a corner of Kanda Ogawacho, approximately 20 years old. The main areas of renovation are part of the exterior facade and building signage, the first-floor entrance, and the common areas on the standard floors (4th floor). The overall concept design concept is "Timeless & Biophilic concept design *". By making good use of the existing granite space, the amount of waste disposal due to demolition was minimized, and concept design was made cost-effective while being mindful of sustainability by fusing old and good materials with new materials. *Biophilic concept design: Design and methods that allow people in a space to feel a connection with nature. [Social Issues/Client Issues/Requests] As the building was over 20 years old, the outdated concept design of the entrance and other areas, as well as the decline in competitiveness within the area, were concerns for the future. In addition, since the building's entrance does not face the main street, the main traffic flow had a somewhat alley-like impression, and there was room for improvement in terms of the building's visibility. Based on these challenges, this project required improving the competitiveness and visibility of the property through renovations to the entrance, facade, and some standard floors. [Solution] To soften the previously dark, back-alley feel of the facade, dynamic wood-grain louvers and indirect lighting were newly installed to create a brighter building face. Inside the entrance, two different textures, glass and natural wood, were used to refresh the old-fashioned feel and aim to improve the morale of the people working there. Sanitary equipment such as toilets and kitchenettes on the office floors were also renovated to meet new standards such as antibacterial properties. Through these comprehensive renovations, the aim is to make the entire building a safe and comfortable place for the people who work there. [Customer Feedback] We are grateful to all the sales, designers, and construction staff at NOMURA Co.,Ltd. for working together as a team on this project, which has now been successfully completed. We appreciate the meticulous support at each phase. We feel that the renovated facade and entrance are functioning perfectly as the new face of the building. <Our Project Members> [Development] Takuya Kitai [Sales & Project Management] Masahiro Harada, Kayu Tatsumi [Research] Wataru Takada [design, layout] Hiroyuki Nii, Sayaka Miyane, Hitoshi Igarashi [Production & construction] Mai Sakai, Tomokuni Hasegawa, Fumiya Sasaki
