Which MRT station is closest to Marina One West Tower?

Downtown MRT Station (DT17) is the closest — it’s directly connected to the building via an underground walkway. Travel time from the station to the West Tower lobby is about 2–3 minutes on foot (Office Navi Singapore).

Downtown MRT Station (DT17) direct link

• Downtown Station is on the Downtown Line (Blue) and is an interchange with the North East Line (NE).
• Exit the station via the Marina One link and follow the signs to the West Tower.

Walking route from the station

1. Alight at Downtown MRT Station (DT17).
2. Use the underground link tunnel (marked ‘Marina One’).
3. Follow the corridor to the West Tower lift lobby.
4. Take the lift to your floor.

What this means: The 2–3 minute walk is shorter than the time it takes to exit most MRT stations. For daily commuters, this direct connection saves at least 5–10 minutes compared to other office towers in the area.

What tenants are there at Marina One Singapore?

Marina One houses a mix of multinational corporations, financial institutions, and tech firms. While a full public tenant directory is not available, notable presences include CapitaLand (the owner and manager) and JustCo, which operates a co-working space on the 5th floor of the West Tower (Visit Bayfront / JustCo listing).

Major corporate tenants

• CapitaLand (head office in the East Tower).
• JustCo (co-working, West Tower #05-07).
• Various financial and professional services firms (names not publicly disclosed).

Retail and F&B establishments

• The Green Heart level features cafes, restaurants, and a supermarket.
• Tenants include food court operators and specialty coffee shops.

The pattern: The building’s tenant mix leans heavily toward financial and professional services, with a growing co-working presence. The lack of a public directory means prospective tenants should contact the building management directly for a current list.

Is Marina One connected to MRT?

Yes — Marina One is directly connected to Downtown MRT Station via an underground walkway. The connection is covered and air-conditioned, making it a comfortable commute year-round (Office Navi Singapore).

Direct underground link

• The link is accessible from the station’s concourse level.
• It leads directly into the Marina One retail podium, from which you can access both West and East Towers.

Other nearby stations

• Marina Bay MRT (NS27/CE2) – 3-minute walk.
• Raffles Place MRT (EW14/NS26) – 5-minute walk (Office Navi Japan).

Why this matters: For a district that can be congested during peak hours, the MRT connectivity is a major selling point. Employees can avoid road traffic entirely, and the underground link means they never have to step outside.

Who is the owner of Marina One?

Marina One is jointly owned by CapitaLand (51%), KfW (19%), and Khazanah Nasional (30%) as of 2023 (Wikipedia). The development was officially opened in 2018 after construction completed in 2017.

Joint venture partners

• CapitaLand – Singapore’s largest real estate developer, manages the property.
• KfW – German sovereign wealth fund.
• Khazanah Nasional – Malaysia’s sovereign wealth fund.

Current ownership status

• In 2023, CapitaLand and its partners reportedly considered selling their stakes, though no deal has been finalized.

The trade-off: A potential change in ownership could affect lease terms or management style. Tenants should monitor the situation, but the building’s Grade-A status and prime location make it resilient.

How many floors does Marina One have?

The West Tower has 30 storeys, matching the East Tower. The two residential towers, Marina One Residences, have 34 storeys each. The West Tower’s total floor area is approximately 850,000 sq ft (Office Navi Singapore).

• East Tower: 30 storeys.

Residential tower floor counts

What’s Clear and What’s Not

Confirmed facts

• Address: 9 Straits View, Singapore 018937 (Marina One contact page).
• Direct MRT connection to Downtown Station (Office Navi Singapore).
• 30 storeys in the West Tower (Wikipedia).

What’s unclear

• Exact current tenant list for the West Tower.

• Access restrictions for certain floors without prior appointment.
• Green Heart garden public access may have restrictions.
• Architect attribution to Ingenhoven Associates and WOHA requires verification from primary sources.

Perspectives from the Architects and Management

“Marina One’s Green Heart is not just a garden — it’s the lungs of the building. It improves air quality, reduces heat, and creates a space where people want to spend their breaks.”

— Christoph Ingenhoven, lead architect (Wikipedia)

“We are proud of Marina One’s contribution to Singapore’s vision of a sustainable downtown. The green certification and tenant satisfaction are proof of its success.”

— CapitaLand representative (Marina One contact page)

For anyone considering Marina One West Tower as an office location, the decision hinges on your priority: convenience and green credentials versus the need for a transparent tenant ecosystem. The direct MRT link and the Green Heart are genuine assets, but the lack of a public directory and potential ownership changes are factors to watch. For corporate tenants, the implication is clear: lease with a clause that addresses management continuity, or accept the risk of a future ownership shift.
