One Sophia— Overview

For more than four decades, the brutalist structure of the former Peace Centre and Peace Mansion at 1 Sophia Road was a familiar landmark in the Selegie district. Completed in 1977, the massive complex functioned as an early example of multi-strata commercial and residential integrated design in Singapore. Over the decades, it evolved into an incredibly complex, fragmented ecosystem. The property housed local printing shops, budget music schools, small legal offices, regional travel bureaus, and late-night karaoke lounges. While it possessed undeniable nostalgia, the aging building stood in stark contrast to the rapid modernization taking place in adjacent zones like Rochor, Bencoolen, and Dhoby Ghaut.

Unlocking the potential of this prime 76,617 square foot site required immense patience, strategic vision, and massive financial capitalization. The property went through four unsuccessful collective sale attempts over a ten-year period. This represents the difficulty of managing multi-tenanted, mixed-use strata properties under Singapore's en bloc laws. The breakthrough finally arrived on 3 December 2021, when a joint venture led by SingHaiyi Group and Chip Eng Seng (CEL Development) successfully secured the property for 650 million Singapore dollars during its fifth tender attempt. This landmark transaction set the stage for one of Singapore's most anticipated urban renewal programs.

Progressing through construction with a targeted temporary occupation permit (TOP) in late 2029, the site is undergoing a dramatic structural transformation. The developer consortium is replacing raw concrete and outdated mechanical infrastructure with an integrated vertical community. Rebranded as One Sophia for the commercial offices and retail zones, and The Collective at One Sophia for the two residential towers, this major District 9 project is designed by the award-winning firm studioMilou in collaboration with ADDP Architects. Rather than inserting a standard, isolated condominium tower, the developers are introducing a biophilic design that aligns with Singapore's vision of a city in nature, offering early-stage investors a front-row seat to the revitalization of the Selegie corridor.

Developing a mixed-use project of this size, requiring the complete demolition of an aging high-density structure and the engineering of three distinct vertical towers, demands deep financial resources and complex engineering capabilities. The consortium behind One Sophia and The Collective brings together some of the most prominent institutional players in Singapore real estate, mitigating execution risks for both commercial and residential buyers.

SingHaiyi Group: A fast-growing real estate group with a diversified portfolio across Singapore, the United States, and Australia, SingHaiyi Group has built a strong reputation for luxury and high-quality residential developments. Its design philosophy emphasizes functional layouts, sustainable design features, and structural excellence. Landmark developments such as The Gazania, The Lilium, and the ultra-luxury Klimt Cairnhill in District 9 showcase SingHaiyi's versatility in delivering both boutique developments and high-end residential towers.

CEL Development (Chip Eng Seng): As the property development arm of Chip Eng Seng Corporation, CEL Development has established a strong reputation for delivering high-quality residential, commercial, and industrial properties in Singapore, Australia, and Vietnam. The company is known for its meticulous project management, functional interior planning, and premium finishes. Its portfolio includes prominent developments such as Grandeur Park Residences, Kopar at Newton, and Park Colonial, demonstrating its ability to create desirable homes that attract both owner-occupiers and tenant markets.

Ultra Infinity: This strategic consortium brings together three experienced local builders and developers: KSH Holdings, SLB Development, and Ho Lee Group. KSH Holdings, an established construction and property development group, holds an A1 grading from the Building and Construction Authority (BCA), allowing it to bid on public and private projects of unlimited contract value. SLB Development, the property development arm of Lian Beng Group, brings extensive experience in suburban and city-fringe residential projects, while Ho Lee Group contributes its structural engineering expertise. The combined capabilities of this group ensure that One Sophia benefits from high-quality construction practices and professional oversight throughout its development phase.

The architectural design of One Sophia represents a major shift from the brutalist concrete style of the former Peace Centre to a modern, open, and nature-integrated vertical community. This design is the result of a creative partnership between French architecture firm studioMilou, led by renowned architect Jean-Francois Milou, and ADDP Architects, one of Singapore's leading architectural practices.

Jean-Francois Milou is highly regarded for his sensitive restoration of historical buildings and his ability to integrate modern structures into complex urban settings, as seen in his work on the National Gallery Singapore. For One Sophia, studioMilou designed a building that respects the unique topography of Mount Sophia while establishing a prominent presence at the intersection of Selegie, Middle, and Sophia Roads. Rather than designing separate, isolated towers, the architects created a cohesive layout where the residential, office, and retail components are integrated through a series of flowing, green architectural structures.

The defining element of this design is the suspended garden, a striking architectural feature that runs along the central axis of the project. These two curved levels of lush greenery hover above the ground, creating a natural canopy over the retail podium and street-level plazas. This design helps reduce the urban heat island effect, provides natural shade, and acts as a visual bridge connecting the development to the green slopes of Mount Sophia. The residential towers are situated behind this green shield, offering residents a peaceful sanctuary that is visually and acoustically insulated from the busy roads below.

To enhance energy efficiency, the buildings feature high-performance double-glazed glass facades that maximize natural light while minimizing solar heat gain. Vertical green walls and integrated planters on the balconies of the residential towers serve as natural shading screens, softening the clean architectural lines of the towers and enriching local biodiversity. By integrating nature into the vertical surfaces of the development, the design blends the built environment with the surrounding natural landscape, providing a serene setting for residents, office workers, and retail visitors alike.

Mixed-use developments in Singapore have consistently commanded a premium over standalone residential projects due to their self-contained environments, convenience, and vibrant street life. One Sophia is carefully zoned to ensure that its residential, office, and retail components operate independently while supporting one another, creating a highly efficient vertical community.

The location of One Sophia at 1 Sophia Road sits at the convergence of three distinct urban planning zones in Singapore: the Orchard Road Shopping Belt, the Bras Basah-Bugis Arts and Heritage District, and the Rochor and Little India Planning Area. This unique position places residents, office workers, and retail operators in a highly central, culturally rich, and incredibly connected neighborhood.

Unparalleled Transit Connectivity: Residents of The Collective at One Sophia benefit from outstanding accessibility, with six MRT stations situated within a one-kilometer radius. The development is located approximately 280 meters from Bencoolen MRT Station on the Downtown Line and 440 meters from Bras Basah MRT Station on the Circle Line. The Rochor MRT Station is also a short walk away, providing direct access to the central and eastern regions of the island.

Crucially, the development is located within comfortable walking distance of the Dhoby Ghaut MRT Interchange. As one of Singapore's largest transport nodes, Dhoby Ghaut connects the North-South Line, the North-East Line, and the Circle Line in a single, air-conditioned underground hub. This dual-line and interchange connectivity means that commuting to the Central Business District at Downtown, Marina Bay, or Raffles Place takes less than ten minutes. For drivers, immediate access to major expressways such as the Central Expressway (CTE), East Coast Parkway (ECP), and Pan-Island Expressway (PIE) ensures smooth journeys to any part of the island.

The Premier Educational Hub: One Sophia is surrounded by some of Singapore's most prestigious tertiary educational institutions, creative arts academies, and primary schools. It is situated just steps from the Singapore Management University (SMU) city campus, making it highly convenient for university professionals and students. Other nearby creative and academic institutions include the School of the Arts (SOTA), Nanyang Academy of Fine Arts (NAFA), LaSalle College of the Arts, and the University of the Arts Singapore. This concentration of higher education creates a reliable, high-quality rental demographic of international students, academic researchers, and professional educators, providing residential landlords with excellent long-term rental demand.

For families with younger children, St. Margaret's Primary School is located within a one-kilometer radius, providing a highly convenient option for daily school runs. Other established schools, such as Anglo-Chinese School (Junior), Stamford Primary, and Farrer Park Primary, are located within a short driving distance, making the development highly suitable for families prioritizing quality education.

Lifestyle, Leisure, and Shopping: The lifestyle offerings around One Sophia are virtually endless. Residents are located a short walk from Plaza Singapura, a massive shopping destination that features a large Cold Storage supermarket, a Golden Village cinema, and an array of retail and dining outlets. The surrounding preservation streets of Rochor, Middle Road, and Prinsep Street are lined with heritage shophouses hosting a diverse mix of traditional coffee shops, trendy cafes, and international restaurants. To the south, the Bras Basah-Bugis district provides rich cultural experiences, with the National Museum of Singapore, Singapore Art Museum, and the historic CHIJMES complex all within comfortable walking distance.

Analyzing a mixed-use commercial and residential project of this scale requires a comprehensive financial perspective that considers the land acquisition costs, construction premiums, and expected exit values. Unlike pure greenfield residential sites, One Sophia's financial modeling is based on its high-density plot ratio and its balanced residential-commercial layout.

Land Cost Analysis and Breakeven Estimates: The consortium purchased the Peace Centre and Peace Mansion site for 650 million Singapore dollars in late 2021. When factoring in the lease top-up premium required to restore the land's tenure to a fresh 99-year leasehold, the land rate translates to approximately 1,426 Singapore dollars per square foot per plot ratio (psf ppr). After adjusting for the seven percent bonus gross floor area (GFA) permitted for the residential portion, the effective land rate is estimated at approximately 1,388 Singapore dollars psf ppr.

To determine the estimated breakeven price, developers must factor in several key components: the cost of demolition, specialized foundation works, building materials, professional architectural fees, financing charges, and marketing expenses. In the 2026 construction market, development costs for premium District 9 mixed developments are projected to bring the developer's estimated breakeven price to a range of 2,300 to 2,450 Singapore dollars per square foot. This solid baseline indicates that the initial launch prices are well-positioned relative to actual construction costs, providing a secure foundation for early-stage capital preservation.

Launch Price Benchmarking: The Collective at One Sophia launched with attractive promotional pricing starting in late 2024, with average unit prices ranging from 2,550 to 2,900 Singapore dollars per square foot depending on unit size, tower stack, and elevation. Studio units commenced from approximately 1.14 million Singapore dollars, while premium one-bedroom suites were priced from 1.35 million Singapore dollars, and two-bedroom deluxe units started at 1.71 million Singapore dollars. For larger spaces, three-bedroom luxury units were introduced from 2.85 million Singapore dollars.

When compared to recent new launches in District 9 and the wider Core Central Region, where transaction prices routinely exceed 3,200 Singapore dollars per square foot, One Sophia represents a highly competitive entry-level price point for prime central district real estate. This price positioning is particularly attractive for buyers looking for capital growth, as the entry price leaves room for future appreciation as the development nears its completion date.

Rental Yield Projections: From an investment perspective, the rental potential of The Collective at One Sophia is supported by its central location and transport connectivity. Drawing comparisons from completed projects in the Dhoby Ghaut and Selegie areas, we project that studio and one-bedroom units will attract strong interest from young professionals and international students. Based on prevailing rental rates in 2026, compact units are projected to command monthly rentals between 3,800 and 4,500 Singapore dollars, translating to a projected gross rental yield of approximately 3.6% to 4.2%. This represents a highly resilient yield compared to standard luxury developments in the central region, making it an excellent option for income-focused portfolios.

Market Scarcity and Strategic Trade-offs: The comparative data highlights the unique position of One Sophia. While boutique developments like Orchard Sophia and Hill House offer the long-term benefit of freehold or 999-year tenures, they lack the immediate convenience, extensive facilities, and dining options of a mixed-use development. Conversely, mega-projects in Bugis like Midtown Modern offer similar mixed-use convenience but at a significantly higher entry price per square foot.

The Collective at One Sophia successfully balances these elements. It offers the lifestyle benefits and capital appreciation potential of a major mixed-use development at a more competitive entry price point than nearby premium developments. This balanced position makes it highly appealing to practical buyers who prioritize active city living, immediate transit access, and strong, reliable rental demand over the premium of freehold land.

The long-term value of a real estate investment in Singapore is heavily influenced by the Urban Redevelopment Authority (URA) Master Plan. One Sophia is positioned to be a major beneficiary of some of the most ambitious urban rejuvenation and greening initiatives planned for Singapore's central districts.

The Pedestrianization of Dhoby Ghaut: A central initiative of the URA Master Plan for the Orchard and Dhoby Ghaut planning zones is the pedestrianization of Orchard Road. To create a greener and more walkable city, plans are underway to divert vehicular traffic from Penang Road, allowing the existing Istana Park to expand to three times its current size. This expanded green space will connect directly with Dhoby Ghaut Green, transforming the area into a massive, car-free urban park suitable for cultural events, family recreation, and community festivals.

For residents of One Sophia, this transformation means having a tranquil park on their doorstep. The reduction in vehicular traffic and the introduction of new landscaping will significantly improve air quality and reduce noise levels, creating a more peaceful environment for the Selegie and Sophia Road neighborhoods.

Seamless Green Connections: The master plan also emphasizes the creation of "Walk-Cycle" green pathways connecting the city's key parks. New elevated pedestrian links and shaded walkways will connect Dhoby Ghaut Green directly to the historical parklands of Fort Canning Park, creating an uninterrupted green belt from the Orchard shopping corridor to Singapore's historic hills. This enhanced connectivity allows residents of One Sophia to transition from their modern urban homes to beautiful natural parks in a matter of minutes, supporting an active, wellness-focused lifestyle.

Precinct Gentrification: The redevelopment of Peace Centre into the modern One Sophia complex is also acting as a catalyst for wider regeneration in the Selegie and Prinsep areas. Aging commercial properties nearby are expected to undergo redevelopment or major upgrades to match the modern standards set by One Sophia. This ongoing gentrification will elevate the profile of the entire neighborhood, positive affecting property values, attracting higher-profile retail brands, and driving long-term capital appreciation for property owners in the precinct.
