Hanoi, September 25, 2025 – OSI Holdings Joint Stock Company successfully held the "Test Pile Pressing Ceremony for the Oriental Mansion Project" at land lot NO 22, formerly part of Thuong Thanh Ward (now Bo De Ward), Hanoi.

In the context of Vietnam’s real estate market shifting strongly to align with international standards on sustainability, ESG (Environmental – Social – Governance) has become an essential criterion. With the Oriental Square by OSI project at Starlake, OSI Holdings aims to lead this trend, delivering a true Grade A ESG office building for the Hanoi market.

Quick to embrace this trend, OSI Holdings conveys the message “not only selling a home, but defining a new standard of living” in each of its developments. Every OSI Holdings project is more than a real estate product – it is a “manifesto” of a refined, sustainable lifestyle with enduring value.

Located at the heart of Hanoi’s new master-planned administrative–economic center, Starlake Urban Area is drawing exceptional attention from investors and the business community alike. Among its flagship developments, Oriental Square by OSI stands out as a true pioneer, setting a new international benchmark for world-class office environments in Vietnam.

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.

In the context of financial market volatility, real estate remains the most preferred asset class thanks to its tangible value, resilience against inflation and long-term profitability. However, not every real estate product delivers the expected results. Successful investors always adhere to two core principles: maximizing real usage value and unlocking sustainable cash flows over time.

Hanoi’s elite are leading a lifestyle migration westward, where prime central positioning, master-planned development, and rare ecological advantages converge. Tay Ho Tay real estate is not merely a residential choice but a symbol of refined living, international standards, and enduring value over time.

Step by step, OSI Holdings has conquered numerous challenges in the real estate arena, rising to become a pioneering developer setting new lifestyle standards through integrated real estate.

In a market often swayed by short-term growth races or “launch fast, flip quickly” trends, OSI Holdings chooses a deliberate and disciplined path, committing to developments that harmonize economic benefits, quality of life, and sustainable urbanization.
