Singapore’s Urban Redevelopment Authority (URA) is revising its Gross Floor Area (GFA) guidelines, a move that could fundamentally alter how developers approach residential and commercial projects. Minister of National Development Chee Hong Tat announced the potential changes on September 21, proposing a shift from rigid GFA limits to a more adaptable system. Under this approach, developers would earn additional floor space by implementing specific requirements, such as sustainability initiatives or heat mitigation strategies.
The GFA serves as a key financial benchmark for developers, determining the total built-up area—including living spaces, circulation areas, and mechanical rooms—that can be constructed on a site. Currently, URA establishes fixed GFA limits for each development, leaving little flexibility for negotiation. The proposed adjustments would allow developers to secure bonus floor space if they meet designated criteria, effectively reducing their land cost per square foot of allowable GFA.
A case study from Lentoria, a District 27 project, highlights the financial implications of GFA adjustments. The site spans 116,455 square feet with a plot ratio of 2.1, yielding a baseline GFA of approximately 244,555 square feet. Acquired through a joint tender by Hong Leong Holdings and Mitsui Fudosan for $276.36 million, the land cost equated to about $1,130 per square foot of plot ratio. If the same site received a 20% bonus GFA uplift, the total allowable built-up area would increase to 293,466 square feet, lowering the effective cost per square foot of GFA to $942, assuming the land price remained unchanged. This demonstrates why developers closely track GFA limits, as even minor adjustments can substantially influence project profitability.

How bonus GFA could reshape projects
While higher GFA does not automatically translate to proportional financial gains, construction costs, land betterment charges, and feature-specific restrictions can offset benefits, it often converts a marginally viable site into one with strong developer interest. The proposed review suggests URA may link bonus GFA to design flexibility and sustainability incentives, expanding on existing programs like the Built Environment Transformation initiative. That program already offers up to 3% extra GFA for productivity enhancements, digitalization, and green features.
Other schemes operate under similar principles. The Conserved Bungalows scheme permits developers to retain historic structures while adding extra floor space, and the CBD Incentive Scheme provides 25% to 30% GFA uplifts for converting older office buildings into residential or hotel uses. Projects such as Newport Residences and Skywaters Residences have leveraged these adjustments to revitalize the central business district.
The Strategic Development Incentive (SDI) scheme applies comparable logic to older commercial buildings, allowing taller structures or mixed-use developments, often with residential components, if they meet redevelopment objectives. These examples confirm that bonus GFA is not a novel concept, though the upcoming review may broaden its application beyond commercial zones into residential projects.

New rules for sustainability and space gains
Under the revised framework, developers may pursue two primary methods to secure additional floor space. One approach involves receiving a fixed percentage uplift when a project incorporates predefined sustainability or heat-resilience measures. The alternative allows certain green or communal elements to be excluded from the overall GFA calculation, freeing space for extra units without increasing the headline GFA figure.
Qualifying features could include extensive shading systems, rooftop gardens, or high-performance façade designs. URA’s statements indicate the agency will tie bonus magnitudes to the level of environmental performance achieved. Projects meeting higher standards could earn larger bonuses, while minimal compliance may result in modest or no additional allowance.
