Marina One Residences: CBD Living with the Circle Line Now Complete
Updated 2026-10-28
Marina One Residences is a 1,042-unit luxury development in the heart of Singapore's Downtown Core, directly connected to the MRT network. With the Circle Line loop completed in July 2026 and 114 units currently listed at an average of S$2,219 per square foot, it remains one of the CBD's most actively traded condominiums.
What is Marina One Residences?
Marina One Residences is a 99-year leasehold condominium at 21 Marina Way, developed by M+S Pte Ltd, a joint venture between Temasek Holdings and Khazanah Nasional. Completed in 2017, the development comprises 1,042 units across two 34-storey towers, with layouts ranging from one-bedroom apartments to four-bedroom units and penthouses.
The defining feature is the Green Heart, a 65,000 square foot landscaped central courtyard with a three-storey cascading waterfall, 386 species of plants and timber walkways. Below the residential towers sits a 140,000 square foot retail podium with a Cold Storage supermarket, restaurants including Majestic Restaurant and Wakanui Grill Dining, and a fitness club. Residents have a 50-metre lap pool, aquatic gym pool, concierge service, private dining rooms, teppanyaki terrace and a putting green.
How well connected is Marina One Residences by MRT?
Marina One Residences has direct underground access to Downtown MRT station on the Downtown Line and is a short walk from Marina Bay MRT, an interchange serving the North-South Line, the Thomson-East Coast Line and the Circle Line. The completion of Circle Line Stage 6 on 12 July 2026, adding Keppel, Cantonment and Prince Edward Road stations, closed the full 33-station orbital loop through Marina Bay.
That loop means residents can now reach the south-western and south-eastern parts of Singapore without transferring through the city centre. Raffles Place MRT is one stop away on the Downtown Line, and Shenton Way is within walking distance. Bus service 400 connects the Marina Bay area to Gardens by the Bay, Downtown and Tanjong Pagar.
How much does a unit at Marina One Residences cost?
There are currently 114 condominiums listed for sale on Hombble, with an average asking price of S$3,448,472 and an average size of 1,579 square feet, which works out to S$2,219 per square foot. Recent URA caveat data paints a slightly different picture at the transacted level: the median price over 64 recorded transactions in 2025 and 2026 sits at roughly S$1,960 per square foot, with most sales falling between S$1,762 and S$2,126 per square foot.
In September 2026, a two-bedroom unit sold at S$2,121 per square foot (S$2.42 million), while a one-bedroom sold at S$1,736 per square foot (S$1.326 million). A one-bedroom in May 2026 set a new per-square-foot low for the development at S$1,702. The gap between asking prices and transacted prices is worth noting for buyers budgeting their offers.
What schools and amenities are nearby?
Downtown Core is not a traditional family neighbourhood, and the nearest government primary school, Cantonment Primary School, is about 1.75 kilometres away. River Valley Primary School and Stamford Primary School are each under three kilometres. For international schooling, OWIS Suntec Campus and ACS (International) Elementary are within the CBD fringe, and HWA International School operates a campus at Marina Square offering the full International Baccalaureate programme from kindergarten through pre-university.
Daily shopping is handled by the retail podium downstairs and Marina Bay Link Mall next door. Tanjong Pagar Centre, Guoco Tower and One Raffles Place are all within a ten-minute walk, providing further dining, retail and grocery options including Little Farms and Jasons Deli. The Esplanade, Gardens by the Bay and the Singapore Flyer are all within the immediate Marina Bay precinct.
Living in Marina One Residences
The development sits at the intersection of the CBD office district and the Marina Bay waterfront, which shapes the day-to-day experience. Weekday mornings are busy with office workers passing through the retail podium, while evenings and weekends are quieter than most suburban estates. The Green Heart courtyard provides a surprising amount of greenery and shade for a city-centre location, and the integration of residential, office and retail within a single complex means most errands do not require leaving the building.
One practical consideration is the 99-year lease. The development is nine years into that lease as of 2026. For buyers comparing against freehold options in the CBD such as The Sail at Marina Bay, the remaining tenure is a factor in long-term capital planning. Rental demand is strong given the location's appeal to professionals working in the financial district.
Outlook for Marina One Residences
The completion of the Circle Line loop strengthens the transport case for Marina Bay as a residential precinct, not just a workplace. URA's long-term plans for the Greater Southern Waterfront, which stretches from Pasir Panjang to Marina East, envision new housing, parks and waterfront amenities that will fill in the area south and west of Marina One over the coming decade.
Transaction volumes remain steady and the spread of recent prices suggests the market has found a relatively stable range around S$1,900 to S$2,100 per square foot for resale units. With 114 listings currently active, buyers have a reasonable amount of choice across unit types. Sellers pricing above the transacted range should expect longer marketing periods.
