Amenities
The Nine is a 30-storey tower over three basement levels at 9 Pham Van Dong in Mai Dich, Cau Giay. GP.Invest — the Toan Cau Real Estate Investment Joint Stock Company — built it with 350 apartments, Morrison Architects of the United States on design and Newtecons as general contractor. Completion came in 2022.
The structural approach is worth knowing because you can feel it inside the apartments: instead of a conventional column grid the building uses load-bearing walls combined with large-format glazing, which removes most of the internal columns and gives the rooms uninterrupted lines and wide views.
The other thing the project is known for is paperwork. GP.Invest handed the first 57 ownership certificates to residents in February 2023, within a few months of handover — at a time when many Hanoi projects were stuck on legal procedures. The developer has made the same claim across its other schemes, and for buyers it is a meaningful signal.

Location and getting around
The tower has two street frontages, on Pham Van Dong and Doan Ke Thien, and sits on the Ring Road 3 alignment. That puts Xuan Thuy and Ho Tung Mau, Hoang Quoc Viet and the route north to Noi Bai airport all within easy reach, and connects through to Tay Ho and Ba Dinh on one side and the Tu Liem districts on the other.
Cau Giay is the part of Hanoi with the heaviest concentration of universities and offices, which keeps the rental market here liquid year-round. The flip side is that Pham Van Dong carries a lot of through traffic, including heavy vehicles, so orientation matters when choosing a unit.
The building includes seven retail and trading floors in the podium along with landscaped space and a rooftop restaurant level, which is a denser commercial component than most residential towers of this size carry.

Who it suits
- Buyers who put legal certainty and a quick certificate ahead of a marketing story
- Families who want a column-free layout and wide glazing
- Tenants working in the Cau Giay office and university cluster
- Owners who want a tower with its own retail floors rather than a standalone block
Before you buy or rent
- Ward boundaries in Cau Giay changed in the 2025 reorganisation. The tower’s historic address is Mai Dich; confirm the current ward on the certificate if it matters for registration.
- Pham Van Dong is a busy arterial road. Ask which side the apartment faces and visit at rush hour.
- With 350 units in one building, check how many are investor-owned and let short term if a settled resident community matters to you.
- Confirm the service charge and whether the podium retail shares access or parking with residents.
