Taisei Corporation
We, Taisei Corporation (President: Yoshiro Aikawa), hereby announce the grand opening of TAISEI SQUARE HANOI, a state-of-the-art office building in the heart of Hanoi City, Socialist Republic of Vietnam (hereinafter referred to as "Vietnam") in September 2024, which has been developed by our local subsidiary, Taisei Development Hanoi Co. Ltd. as the new office development project (this “Project”).
Taisei Group has been involved in and responsible for every aspect of this Project, from investment and development to design, construction, and operational management. We confidently position TAISEI SQUARE HANOI as the flagship of our international business. With the goal of providing the Vietnamese market with a Japanese-quality, comfortable, and eco-friendly workplace, this Project has also earned the distinction of being the first leased office building in western Hanoi to receive LEED certification. We hope that this Project sets a new standard for office buildings in Vietnam and contributes to enhancing the overall office environment in the region.
At TAISEI SQUARE HANOI, we have a wide range of tenants, including companies from Japan and Vietnam, as well as American, French, Korean, and Taiwanese firms.

LOCATION MAP
The Project site is located approximately 8 km west of central Hanoi (Hoan Kiem Lake) and enjoys a prime position along Ring Road 3, providing excellent access to Noi Bai International Airport and key industrial parks on the outskirts of Hanoi. Adding to its convenience, the adjacent Roygent Parks Hanoi*1- a hotel and serviced apartment jointly developed by Daiwa House Industry Co., Ltd. and Taisei Corporation - offers ideal accommodations for business travelers and expatriates, catering to both short- and long-term stays.

BULDING’S NAME AND LOGO
The name "SQUARE" reflects both the simple, square shape of the building and its role as a central hub, or plaza, in the western area of Hanoi. The red dot symbolizes Japan, while the letter "T" stands for TAISEI and references the T-square, a vital tool in architectural design during the analog era. By honoring the craftsmanship spirit, we have embedded our commitment to creating an office environment that embodies the finest qualities of Japanese standards.

DESIGN CONCEPT
The design motif draws inspiration from the clean, restrained aesthetics of Japanese architecture, characterized by its precise horizontal and vertical lines. The combination of wood and stone-like materials adds warmth and tranquility to the monochrome, formal setting, creating an office space that is both calm and inviting.

BUILDING FEATURES
By leveraging Taisei Corporation's advanced technical expertise and incorporating innovative structural design, we have created a spacious, well-proportioned, column-free area that allows for highly efficient office layouts. In addition, we are addressing common concerns in Hanoi office buildings - such as toilets, air conditioning, and elevators - to ensure a comfortable and seamless working environment.
- ①Toilets: Each toilet in the building has been designed to Japanese standards and is equipped with a TOTO Washlet - a hot water bidet system that is still a rarity in office buildings in Vietnam. Additionally, the women's restroom includes a powder corner a, dedicated space for makeup and personal grooming, for added convenience.
- ②Air Conditioning: The building is equipped with energy-efficient, individual air conditioning units manufactured by Panasonic. Each zone has its own temperature control, ensuring consistent comfort regardless of season or building orientation. This system allows for flexible working styles, free from time-based constraints, by offering adaptable climate control throughout the office.
- ③Elevator: In addition to the eight Fujitec high-speed elevators for office floors, there is also an elevator dedicated to the basement, allowing access to the office floor from the first floor without waiting time even during peak hours. As an office for the post-corona era, we have also introduced touchless buttons and plasma ion clusters.

BUILDING MANAGEMENT
The building will be managed by Taisei Development Hanoi Co. Ltd., in collaboration with the following Japanese partner companies, to ensure the delivery of high-quality services that meet the standards of Japanese excellence.
- Security: ALSOK VIETNAM SECURITY SERVICES JSC*2
To ensure residents and visitors enjoy peace of mind 24/7, we maintain a comprehensive security system that includes access management, regular patrols, and continuous security camera monitoring, all in accordance with our specialized security plan. - Cleaning: MEIBI VIETNAM Co., Ltd.
Our mission is to preserve the beauty and hygiene of the building, fostering an environment of excellence. Through our meticulous cleaning practices, we maintain the highest standards of sanitation, ensuring that residents and visitors alike can experience a comfortable and inviting atmosphere. - Technical Maintenance - Quality Control: VISAHO Joint Stock Company*3
In addition to our daily equipment management, our highly skilled and experienced staff is dedicated to responding swiftly and courteously to any equipment failures. We also prioritize comprehensive training for all team members to cultivate a genuine spirit of hospitality, ensuring that every interaction reflects our commitment to exceptional service.

INTRODUCTION OF CURRENT RETAIL TENANTS
We are actively seeking to attract commercial tenants to the first and second floors, enhancing amenities for office workers. Vietnam has seen a diverse array of cafes emerge, and we are pleased to welcome WAYNE'S COFFEE*4 - a global cafe brand originated in Sweden - to our building. Additionally, we’re excited to announce that PIZZA 4P’s*5, an Earth to People restaurant on a mission to Make the World Smile for Peace through its Japanese-Italian cuisine and commitment to quality ingredients, is set to begin operations soon in Hanoi.
