In the context of the luxury real estate market continuously raising standards in design and amenities, the Sun Grand City Tay Ho complex complex—one of the landmark developments in Tay Ho District, Hanoi—continues to make its mark by incorporating KBB automatic revolving door solutions into its main lobby. This scope was directly implemented by Sonha Auto, playing a significant role in elevating the reception space, optimizing operational efficiency, and reinforcing the overall prestige of the project.
Introduction to the Sun Grand City Tay Ho Complex project
Sun Grand City Tay Ho View is strategically located in Tay Ho District and developed on a 16,000 m² site, comprising nine towers ranging from 16 to 39 floors, along with three interconnected basement levels. With advantages in transportation infrastructure, West Lake scenery, and convenient connectivity to the city center, the project is regarded as one of the key highlights of the luxury real estate market.
Sun Grand City Tay Ho View is developed as a multifunctional mixed-use complex, harmoniously integrating residential living, commercial, and service spaces. With a large scale and well-structured master planning, the project places strong emphasis on user experience and long-term sustainable operational value.
Positioned in the high-end segment, the project targets clients with stringent requirements for living quality, amenities, and spatial image. From architectural design and finishing materials to technical systems, every element is carefully selected to meet high standards of aesthetics, safety, and comfort.
For luxury complexes, the main lobby is not merely an entrance area but the space that most clearly reflects the project’s prestige, architectural style, and operational quality. A standard-compliant lobby must simultaneously meet multiple requirements:
- High aesthetics, harmonized with the overall architectural concept
- Effective control of pedestrian traffic flow
- Assurance of comfort, safety, and user experience
- Contribution to energy optimization for the entire building
For this reason, the selection of entrance solutions for the main lobby of Sun Grand City Tay Ho View was given special attention by the developer, with KBB automatic revolving doors being identified as the most suitable solution.

The completion of the KBB automatic revolving door installation at Sun Grand City Tay Ho View marks an important milestone in the overall project completion process. This scope contributes to the refinement of the lobby space, enhances operational efficiency, and reinforces the premium positioning of the complex. Sonha Auto was entrusted to implement the installation of three KBB automatic revolving door systems with a diameter of 3 meters at the main lobby area. The execution was carried out on schedule, in strict compliance with the project’s technical requirements and safety standards.
The completed KBB automatic revolving door system not only meets technical demands but also contributes to the creation of a refined, modern, and luxurious appearance for the main lobby of the complex.
