GLS Sites

Government Land Sales sites and tender data

Understanding GLS Sites

Key Takeaways

  • Map data is refreshed from URA, HDB and OneMap APIs — hover any marker for live values.
  • Use the filter panel to narrow results by district, bedroom type, price range, or tenure.
  • Click any marker or polygon to drill down into the underlying property or area detail.

What It Does

The Government Land Sales (GLS) programme is how Singapore's government releases state land for private development. Sites come in two lists: the Confirmed List (guaranteed for tender) and the Reserve List (triggered only when a developer applies). GLS supply directly controls new private housing stock.

Why It Matters

How GLS Affects Prices

  • High-bid sites: Record land bids push new launch prices higher, setting a floor for surrounding resale values. The Zion Road site (D9) was awarded at ~$1,200 psf ppr — signalling $2,500+ PSF launches.
  • Supply concentration: Multiple sites in the same district (e.g., Lentor corridor with 5+ projects) can create temporary oversupply, softening near-term prices but building long-term township value.
  • EC sites: Executive Condominiums from GLS offer a hybrid path — HDB eligibility at launch, privatised after 10 years. Tampines and Tengah EC sites are key 2026 launches.

Investment Implications

Watch for districts with no upcoming GLS supply — limited new stock supports resale premiums. Conversely, districts with multiple confirmed sites may see short-term competition but long-term transformation (as seen in Tengah, now Singapore's newest town). Reserve list sites are wildcards — their activation signals developer confidence in that micro-market.

How It Works

  • Pan and zoom to the area of Singapore you are interested in.
  • Use the filter panel to narrow results by district, bedroom type, or price range.
  • Hover any marker or polygon for a tooltip with exact values.
  • Click a marker to open the underlying property or area detail page.

Examples

D22 Tengah confirmed list site: estimating supply impact on nearby condos

Inputs
Site type
Confirmed List — guaranteed tender
Location
Tengah Plantation (D22)
Estimated yield
~560 residential units
Nearby condos
Copen Grand EC, Novo Place EC (within 1km)
Results
D22 current pipeline
3 confirmed sites, ~1,400 estimated units over 18 months
Absorption benchmark
D22 average monthly take-up ~45 units
Supply/demand ratio
~31 months of forward supply at current absorption

How to read this: A confirmed GLS site in D22 adds supply certainty: this development WILL be launched, introducing competitive inventory for existing nearby owners. 31 months of forward supply at current absorption rates is elevated — above the 18-month equilibrium level — which historically correlates with developer pricing restraint and softer secondary market appreciation. An owner of a nearby D22 EC should monitor whether the confirmed list supply ratio improves or worsens with each GLS announcement cycle. The map makes the spatial concentration of supply visible: if 3 confirmed sites cluster in the same 2km radius, the supply pressure is real, not diffuse.

Reserve list site near Zion Road: reading developer interest signals

Inputs
Site type
Reserve List — triggered only on developer application
Location
Zion Road (D3, RCR)
Site area
~0.85ha, estimated 350 units
Context
Adjacent to River Valley / Robertson Quay RCR demand zone
Results
Reserve list status
Not yet triggered (no application)
Interpretation
Developers not yet bidding — demand insufficient at current price levels
Nearby condo benchmark
D3 RCR median ~$2,200 PSF
Trigger signal to watch
Application filed = developers see profitable launch price above $2,200 PSF

How to read this: A reserve list site that has not been triggered is a demand signal as informative as one that has. Developers apply for reserve list sites only when they are confident the land can be profitably developed at current or near-term market prices. The Zion Road site sitting untriggered means no developer currently believes launch prices justify the land acquisition cost — which tells a secondary market buyer that developer competition in D3 is not imminent. If the site is triggered in the next 6 months, that signals developer confidence in D3 pricing, which is a positive signal for nearby resale values. The map tracks this status in real time.

Tips & Pitfalls

Expert Tips

  • Zoom out first to spot macro patterns before diving into individual districts.
  • Compare this map against the rental yield map to find high-demand, low-price outliers.
  • Use the legend to understand colour encoding — the same colour can mean different things on different maps.

Common Pitfalls

  • Judging a district by headline colour alone — the underlying sample size varies wildly across Singapore.
  • Confusing median with mean when both are shown — means are skewed by luxury outliers.
  • Forgetting that new-launch prices are discounted — resale prices are a better benchmark for fair value.

Frequently Asked Questions

Where does the map data come from?
Data is sourced from URA (Urban Redevelopment Authority), HDB, OneMap, and official Singapore government APIs, refreshed monthly.
How often is the map updated?
Transaction-based maps refresh monthly as URA and HDB publish new data. Planning layers (Master Plan, GLS) update as gazetted.
Can I filter by district or bedroom type?
Yes — use the filter panel on the map. Filter state is preserved in the URL so you can share a deep link to a specific view.
