3 recent rule changes to floor area, land betterment and remnant land that will likely affect future property prices and en bloc sales

Over the past few weeks, several developments have taken place that many analysts predict will impact future property prices.

If you're a homeowner planning to buy or upgrade to a new property beyond the middle of next year, you might want to take note of these changes.

1. New definitions to floor area may see smaller air-con ledges

In early September, the Urban Redevelopment Authority (URA) released a circular to harmonise floor area definitions currently adopted by our four government agencies – URA, Building and Construction Authority (BCA), Singapore Civil Defence Force (SCDF) and Singapore Land Authority (SLA).

To take effect from June 1, 2023, the intent is to coordinate submissions across agencies and ensure improved productivity for the built environment profession.

Today, URA uses gross floor area (GFA) to measure building intensity, but the current measurement includes the full thickness of external walls and excludes voids.

SLA, on the other hand, uses strata area to demarcate ownership, but is only measured up to the middle of the wall and may include voids.


Discrepancies like these result in Qualified Persons (QPs) such as architects and engineers spending a lot of time calculating various floor areas to meet different agencies' regulatory requirements.

Another scenario is when property owners want to carry out addition and alteration works within their strata units. Doing so may increase GFA but not strata floor area.

For example, this confusion happens when they add an additional slab over an internal void space.

Thus, from June 1, 2023, the following changes will come into effect:

b. All strata areas will be included as GFA.

c. All voids will be excluded from the strata area.

d. BCA and SCDF will adopt an aligned definition for SGFA (statistical gross floor area) computation.

In essence, the harmonisation will help ease submission processes to fulfil different agency regulations and everyone can live harmoniously from June 1, 2023 onwards, right?

Not exactly.

Since all strata areas will be computed as GFA, all previously uncovered areas that form part of the strata area (but not GFA) will now fall under GFA.

If you remember in 2009 and 2013, URA had to revise the rules to include planter boxes, bay windows, private enclosed spaces and private roof terraces as GFA (when they weren't prior).

What happened then was that developers were creating balconies with large planter boxes and wide-open private roof terraces (because they're cheaper to construct than interiors) and charging homebuyers a significant amount for them.

The same thing happened to air-con ledges too, which at the current moment, are not counted as part of GFA (as long as they're up to one metre wide).

In 2017, 200 homeowners in La Fiesta in Sengkang, complained that some of their air-con ledges were up to five metres long (or around nine square metres) – enough to build a common bedroom these days.

In general, private condo developers usually earn four to five per cent of the total saleable area for air-con ledges. The affected La Fiesta residents estimated that they paid an average of $18 milllion in unused space for those ledges.

So, with the upcoming rule change from mid-2023, air-con ledges that are part of a strata unit will count as part of GFA – which should provide some relief to concerned homeowners.

This is because with air-con ledges now being part of GFA, developers are now forced to rethink how best to optimise the use of total floor area for the apartment – since they form a factor in the maximum number of units developers can build and the eventual per square foot (psf) price.

Note, however, that for the maintenance and security of air-con condenser placements, QPs should still comply with BCA's design.

In general, most air-con ledges should be three to five square metres (about 32 to 54 square feet) and will take up 3 per cent of total floor space.

Another area of change is in the strata void area, which will be excluded from strata area computation. This effectively removes it from any GFA inclusion based on the redefinition. In the past, some developers have included strata void areas in their total saleable area, which effectively lowers the per square foot price of the unit. PHOTO: 99.co

As the total saleable area against GFA (after GFA bonuses like balcony incentives, etc.) decreases for developers, they'll need to now find new ways to increase efficiencies, such as reducing construction cost or bidding (and hopefully winning) land parcels at a lower price.

This may not necessarily be the case all the time, especially for hotly contested land parcels and higher construction costs in a post-pandemic world.

In other words, some of these costs may be passed on to homebuyers in the form of higher psf prices. It is thus prudent to closely monitor winning land bid prices before and after June 2023.

Alternatively, we may see some future developments where air-cons for several apartment units from the same block are combined in a common area, which would exempt them from GFA calculations (up to two metres in width).

Another potential change may see better-ventilated designs to improve wind flow into the house, in lieu of additional air-con condensers (and thus, smaller ledges).

2. Land Betterment Charge rates increased for both non-landed and landed residential use due to recent high-value land sales

Besides floor area definitions, the government has also increased Land Betterment Charges (LBC) for non-landed residential, landed residential, commercial and industrial groups.

Being a consolidation of the Development Charge (DC), Temporary Development Levy (TDL) and Differential Premium (DP), LBC is reviewed and revised every six months and is a payable tax when developers want to enhance a site (eg. additions and alterations) or build bigger projects (eg. en blocs).

For the period between Sept 23 to Feb 28, 2023, the LBC rate for non-landed and landed residential developments have increased by an average of 12.9 per cent and 10.2 per cent respectively.

This is in stark contrast to the 0.3 per cent and 4.8 per cent in respective average increases over the previous six months (March 2022 to August 2022).

We should point out that the average DC rate increases for non-landed and landed residential developments in the prior 6 months (September 2021 to February 2022) were 6.3 per cent and 10.9 per cent respectively.

Average rate changes (from previous 6 months)

Non-landed residential 0.30 per cent 6.30 per cent 0.30 per cent 12.90 per cent
Landed residential 1.50 per cent 10.90 per cent 4.80 per cent 10.20 per cent
Commercial -1.50 per cent -0.70 per cent 0.70 per cent 5.40 per cent
Industrial 0 per cent 0 per cent 2.20 per cent 2.30 per cent

LBC rates are closely watched because they usually indicate the rise or fall in land prices based on property types and geographical sectors. Here are the detailed rate charges based on property type and geographic sectors.

Based on the average rate increases across all four property types, it shows that land values from recent sales, such as en blocs (eg. Lakeside Apartments and Park View Mansions), shophouses, offices, retail and so on, have generally gone up.

With higher LBC rates, some developers may steer clear of participating in en blocs, or if they do, some of these redevelopment cost increases may end up being transferred to future homebuyers.

3. Revision to the sale of remnant land

The third change we want to highlight is the recent rate charge for the sale of remnant land.

Remnant land is State land which is incapable of independent development due to its small size or irregular shape.

They can sometimes be amalgamated with adjoining private lands to enhance the economic value and use of the private land.

In early 2021, a 6042-sqft freehold "remnant land"marked as Residential at Sixth Avenue was put up for auction. Surrounded by state land, this plot had a guide price of S$3m and attracted an unprecedented 100 enquiries pre-auction.

URA data shows a 4,532-sqft plot there being sold for S$3.05m (S$673 psf) in 2015.

Prior to Sept 1, the value of remnant land is based on 50 per cent of the full land value. This value is determined by applying a factor of 5/7 to the applicable LBC rate.

However, from Sept 1 onwards, remnant land will be valued for sale based on 100 per cent of the full land value for all property types (except places of worship, and civic and community institution use, which remains at 50 per cent).

The value will be determined by applying the factor of 10/7 to the applicable LBC rate.

This will definitely impact collective sales which include purchasing remnant land to enhance gross floor area. Once again, the higher cost here may end up being transferred to future homebuyers in the end.
