As Hanoi’s office market is shifting strongly toward green workspaces, Grade A offices with green certification are becoming increasingly scarce and highly sought after. In Starlake, the new master-planned hub of the capital, demand is surging among businesses prioritizing sustainable workplaces. According to Savills, by Q2 2025, 41 percent of Hanoi’s Grade A office supply had achieved green certification, with green projects commanding rental premiums of 10 to over 20 percent.

Within this trend, Oriental Square by OSI stands out as a pioneering symbol. Developed by OSI Holdings, it is a green office building positioned at the heart of Starlake, embodying an international-standard philosophy of sustainable development.

1. Starlake as the new master-planned center and the green office trend in Hanoi

Over the past decade, Hanoi has witnessed a significant shift in investment flows, particularly in commercial and office real estate. Previously concentrated in Hoan Kiem, Ba Dinh and Cau Giay, businesses are now moving westward, where integrated planning, ample land reserves and modern infrastructure prevail.

Standing out in this shift is Starlake Tay Ho Tay, designed to become the new administrative, economic and commercial hub of the capital. With its proximity to West Lake, direct access to arterial roads such as Vo Chi Cong and Nguyen Van Huyen, and adjacency to the diplomatic quarter, Starlake is ideally positioned to serve as the “new capital” for experts, multinational corporations and high-quality businesses.

Beyond location advantages, Starlake is also embracing a new wave of green development. This is an inevitable trend, as companies increasingly seek sustainable workplaces that conserve energy and support employee well-being. According to CBRE, in Vietnam, the proportion of businesses prioritizing green-certified or eco-designed buildings has grown by over 35 percent in just five years. Features such as natural lighting, greenery and energy-saving solutions not only help protect the environment but also enhance productivity and employee retention.

In this context, the arrival of Oriental Square by OSI in central Starlake is clear evidence of strategic foresight: capturing the green office trend and creating sustainable value for both businesses and investors.
