The Tampines Trilliant
Imagine an Executive Condominium that started life in 2011 with HDB-style restrictions, crossed the five-year MOP threshold in 2020, and then quietly hit full privatisation in 2025 — opening its resale gates to foreign buyers, permanent residents and the broader investor pool for the first time. That is The Tampines Trilliant (as of 2026-05), Sim Lian's 670-unit Tampines EC that has just stepped out of the EC chrysalis at a moment when Tampines Regional Centre is reasserting itself as Singapore's most credible eastern sub-CBD.
For the buyer-investor weighing Trilliant against fresher Tampines stock like Treasure at Tampines, CityLife @ Tampines, or the impending Tampines Court redevelopment cohort, the question is sharper than it looks: does a post-privatisation EC on year 15 of a 99-year lease offer better risk-adjusted runway than a brand-new 99-year private launch — especially with the Cross Island Line (CRL) due to make Tampines a triple-line interchange? This review walks through what the numbers say (as of 2026-05) and where the trapdoors are.
The headline numbers (as of 2026-05):
- Developer: Sim Lian Group, an established Singapore developer with a track record across ECs and private launches in the East and North-East regions.
- Site: Tampines Central 7, District 18 (Tampines / Pasir Ris) — the heart of Tampines Regional Centre, one of three URA-designated regional centres in Singapore.
- Tenure: 99-year leasehold commencing 2011 — approximately 84 years remaining as of 2026-05. Past year 30 the resale optics begin to matter; the CPF and financing inflection points sit at 60 years remaining (so roughly 2047).
- Type: Executive Condominium (EC). TOP achieved approximately 2015, Minimum Occupation Period (MOP) cleared 2020, full privatisation in 2025 — meaning the project is now treated as a private condo for resale purposes, with no buyer-citizenship restrictions.
- Scale: 670 residential units across multiple blocks. Unit mix spans typical EC formats from 3-bedroom through 5-bedroom and penthouse configurations.
- Stamp duty: Standard BSD applies for citizens; ABSD layered by buyer profile. For PRs and foreigners now able to buy post-privatisation, ABSD is material — model effective cost with the stamp-duty calculator.
Overview & Key Facts
The Tampines Trilliant is a 670-unit executive condominium developed by Sim Lian Group, one of Singapore’s most prolific EC developers with a track record spanning Treasure Crest, Wandervale, and Clover By The Park. Completed in 2015 on a 99-year lease from 2011, the development comprises 12 blocks of 15 storeys on a 22,000-square-metre site along Tampines Central 7 — placing it squarely within the Tampines Regional Centre, Singapore’s largest and most established suburban hub.
Having passed its Minimum Occupation Period in 2020, The Tampines Trilliant is now fully open to the resale market. At a current average of $1,669 psf with a gross rental yield of 3.42% and median rent of $4,300, the development offers a compelling value proposition in the Tampines corridor — undercutting Treasure at Tampines ($1,583 psf for a much larger development) on yield while providing the mature EC community and generous unit sizes that Sim Lian is known for.
The Tampines Trilliant’s defining advantage is its location within walking distance of the Tampines triple-mall cluster (Tampines Mall, Tampines 1, Century Square) and Our Tampines Hub. Few ECs in Singapore can claim this level of retail and civic amenity density at their doorstep. The trade-off is MRT access: Tampines MRT is approximately 970 m away, a 12–15 minute walk that pushes the boundary of comfortable daily commuting on foot.
Location & Connectivity
The Tampines Trilliant occupies a prime position within the Tampines Regional Centre — the first and most mature of Singapore’s decentralised commercial hubs, developed over three decades to be genuinely self-sufficient. The triple-mall cluster of Tampines Mall, Tampines 1, and Century Square is approximately 800 m away (a 10-minute walk or single bus stop), providing comprehensive retail, F&B, cinema, supermarket, and banking services. Our Tampines Hub — Singapore’s largest integrated community and lifestyle hub — adds a swimming complex, hawker centre, library, polyclinic, and sports facilities to the neighbourhood equation.
The school catchment is a genuine strength. Poi Ching School sits just 520 m away, well within the 1 km priority-enrolment radius. Junyuan Primary (460 m), East Spring Primary (600 m), and Tampines North Primary (550 m) provide additional options within comfortable walking distance. For secondary schools, Tampines Secondary, East Spring Secondary, and Tampines North Secondary are all within 1 km.
Healthcare access is strong: Changi General Hospital is a 10-minute drive, and Our Tampines Hub houses a polyclinic for routine medical needs. The Tampines Expressway (TPE) is accessible within a 5-minute drive, connecting to the CTE (toward the CBD) and KPE (toward Changi Airport) within 10 minutes off-peak.
Schools & Education
5 primary schools within the 1 km Priority Phase balloting radius.
| School | Type | Distance |
|---|---|---|

Facilities
Sim Lian has equipped The Tampines Trilliant with a well-rounded facility set that prioritises family use. The aquatic centrepiece comprises four pools: a lap pool for fitness swimmers, a spa pool for relaxation, a wading pool for toddlers, and a meditation pool for quiet reflection — a thoughtful segmentation that prevents the pool-crowding problem common in mega-ECs. The gymnasium is well-equipped with cardio and strength training apparatus, and the tennis court provides a genuine recreational asset for racket-sport enthusiasts.
Beyond the pools, the development offers BBQ pavilions, a function room for private events, a library corner, a sauna, and a children’s playground. The facility provision is comprehensive without being extravagant — every amenity serves a clear purpose, reflecting Sim Lian’s pragmatic approach to EC development where value-for-money matters more than resort-style spectacle.
“The facilities here are genuinely family-friendly. Four pools mean we never have to compete for swimming space, even on weekends. My kids use the playground daily, and we book the BBQ pit at least twice a month. The tennis court is a nice bonus. It’s not a fancy resort-style development, but for a Tampines EC with this much space and these prices, we’re very happy with what we got.”

Maintenance standards are generally positive, with the MCST keeping common areas and pools in good condition. The 670-unit scale means the development is large enough to benefit from economies of scale on maintenance costs but small enough that facilities are not perpetually overcrowded — a balance that larger developments like Treasure at Tampines (2,203 units) struggle to achieve.
Unit Sizes & Layout
As an executive condominium, The Tampines Trilliant offers exclusively three-bedroom, four-bedroom, and penthouse configurations — ranging from 872 sqft to 2,465 sqft. The focus on larger units reflects the EC mandate of serving families, and the sizing is genuinely generous: three-bedrooms average around 1,000 sqft and four-bedrooms around 1,300 sqft, meaningfully larger than the compressed layouts of current new launches where three-bedrooms have shrunk to 700–800 sqft.
The 12-block, 15-storey configuration means most units have reasonable separation from neighbouring blocks, though inner-facing units in the central clusters may experience some overlooking. High-floor units enjoy views across the Tampines roofscape, with north-east-facing stacks offering glimpses of the Tampines Eco Green corridor. The penthouses at 2,465 sqft represent some of the most spacious EC penthouses in the Tampines district, with roof terraces that provide genuine outdoor entertaining space.

Neighbourhood Comparison
In the Tampines EC and condo corridor, The Tampines Trilliant ($1,669 psf, 99-year from 2011, ~84 years remaining) competes with two dominant neighbours. Treasure at Tampines ($1,583 psf, 99-year leasehold) is the mega-development option — 2,203 units with extensive facilities at a lower PSF, but sharing amenities among a much larger population and located further from the Tampines mall cluster. The Trilliant offers a smaller, more manageable community with comparable unit sizes. Aurelle of Tampines ($1,768 psf, 99-year from 2024) is the new-launch EC option, commanding a 6% PSF premium for brand-new finishes and a fresh 99-year lease, though it lacks the proven track record and established community of The Trilliant.
The Trilliant’s competitive advantage is its mature Tampines Central location combined with post-MOP liquidity and the highest yield in the cluster (3.42%). Buyers choosing between the three are weighing proven value and rental income (Trilliant) against rock-bottom entry price and mega-scale facilities (Treasure) or a fresh lease and new finishes (Aurelle). For income-focused buyers who value the Tampines ecosystem, The Trilliant is the balanced choice.

What Residents Say
“One of the best and most spacious unit layouts I’ve seen in an EC. Our four-bedder at 1,300 sqft feels genuinely roomy — the kitchen fits a full dining table, the master bedroom is enormous, and even the helper’s room is usable as a study. It’s definitely a family-friendly development with resort feels, and the location near Tampines Central is unbeatable for daily convenience.”
— Owner-occupier, four-bedroom, since 2020 (PLB Insights)
“We bought here specifically for Poi Ching School — it’s a 5-minute walk and our daughter got in during Phase 2C. The Tampines Mall cluster is close enough for weekend shopping, and Our Tampines Hub is where we go for swimming and the library. MRT is a bit of a walk but we take the bus — one stop to Tampines interchange. For a family with young kids, the trade-offs are very acceptable.”
— Owner-occupier, three-bedroom, since 2022 (EdgeProp)
“I rent out my three-bedder here and it’s been tenanted continuously since MOP. Current rent is $4,300 which gives me over 3.4% yield. The Tampines location sells itself to tenants — the malls, the schools, the bus interchange, the polyclinic. The only feedback from tenants is the MRT walk is a bit long, but the bus options compensate. Solid investment for the price.”

1. The post-privatisation moment — what changed in 2025 (as of 2026-05)
EC privatisation works in two stages. Five years after TOP (the MOP), resale opens to Singapore citizens and PRs. Ten years after TOP, the EC fully privatises — at which point it is treated as a regular condominium and is sellable to foreign buyers on the same terms as private stock. Trilliant cleared MOP in 2020 and hit the ten-year threshold in 2025. That structural demand expansion — adding the PR pool from 2020 and the foreign-buyer pool from 2025 — is the single most underappreciated catalyst for ECs of this vintage.
The practical implication: PSF discovery post-2025 should re-base against private 99-year stock in the same district, not against EC comparables. Owners who held through MOP often see a step-change in resale velocity once full privatisation lands.
2. Tampines Regional Centre — the underrated sub-CBD
Tampines is one of three regional centres designated under URA's decentralisation policy (alongside Jurong East and Woodlands). The cluster around Tampines MRT hosts the IRAS building, CPF Tampines, OCBC and DBS regional offices, and Singapore Post Centre — a concentration of white-collar employment that supports a structural rental floor for surrounding residential stock. Trilliant is within a 7-10 minute walk of this commercial cluster, which means the same unit can serve a CBD-bound commuter, a Tampines-employed tenant, or a Changi Business Park renter (one EWL stop away).
3. Tri-line MRT — the CRL upside
Tampines MRT today is a dual-line interchange (EWL + DTL). The Cross Island Line, with its Tampines station scheduled within the broader CRL Phase 1 build-out, will make it a triple-line interchange. CRL's north-east alignment opens orbital connections to Loyang, Punggol, Hougang and eventually Bright Hill and Clementi — bypassing the city centre for east-to-north-east commutes. That is a meaningful upgrade for renters working in industrial/business-park nodes outside the CBD. See the URA Master Plan overlay for the CRL alignment context.
4. The retail and lifestyle stack
Few OCR locations carry three full-service malls within walking distance. Tampines Mall (Capitaland), Century Square (Frasers) and Tampines 1 (Allgreen) anchor the town centre with overlapping but distinct tenant mixes — supermarket density, F&B variety, cinema, banking and medical. Our Tampines Hub (the integrated community-sports-library complex) adds a fourth pole. For families, this density compresses weekend logistics; for tenants, it underwrites a lifestyle premium that pure-residential suburbs struggle to match.
5. Lease year 15 — pricing the runway honestly
At ~84 years remaining (as of 2026-05), Trilliant is past the "fresh launch" optics window but well clear of the 60-year CPF inflection. The pricing question is whether buyers credit the 15-year head-start the original EC buyers got, or whether they price purely off remaining lease. Empirically, the market discounts older-lease stock against fresh launches but the gap narrows materially when the older project carries structural advantages (regional centre, tri-line MRT, mall cluster) that the new launch cannot replicate. Use the lease-decay calculator to model the discount you should be willing to accept.
6. EC quantum-cap dynamics
ECs were originally sold with a price cap (a function of HDB income ceiling and developer pricing discipline). That artificial quantum ceiling tends to anchor resale psychology even years post-privatisation — buyers reference "what an EC should cost" rather than "what a privatised D18 condo should cost". That can be a feature (entry-PSF discount vs private launches) or a bug (slower mark-to-market on the upside). For investors, the read-through is that yield-on-cost can be attractive at entry but capital appreciation may track the broader OCR market rather than outperform.
7. The 670-unit absorption question
Trilliant's 670 units sit in a Tampines competitive set that includes Treasure at Tampines (~2,200 units, TOP 2023), CityLife @ Tampines (~514 units, TOP ~2016), and the future Tampines Court redevelopment cohort (an en-bloc site that, when redeveloped, could add 1,800+ units). That means resale and rental cycles compete with a deep pool of comparable stock. The investor stress test is rental at 85% occupancy and exit-price scenarios assuming Tampines Court hits the market mid-hold. Check the new-launches and pipeline map for incoming Tampines supply.
How The Tampines Trilliant stacks against its closest Tampines peers (indicative, as of 2026-05; verify with current listings):
| Project | Tenure | Units | TOP | MRT | Distinguishing factor |
|---|---|---|---|---|---|
| The Tampines Trilliant | 99yr from 2011 (~84yr) | 670 | ~2015 | Tampines EWL/DTL ~8-10min walk | Post-privatisation EC (2025), regional centre access |
| CityLife @ Tampines | 99yr from 2012 (~85yr) | 514 | ~2016 | Tampines EWL/DTL ~10min walk | EC, smaller scale, similar privatisation timeline |
| Treasure at Tampines | 99yr from 2018 (~91yr) | 2,203 | 2023 | Simei EWL / Tampines West DTL | Mega-scale private, fresh lease, deeper amenities |
| Tampines Court (future) | 99yr (new, TBD) | ~1,800+ | ~2024 | Tampines EWL/DTL ~12min walk | En-bloc redevelopment, future launch cohort |

Who The Tampines Trilliant fits best
The Tampines Trilliant suits three buyer archetypes most cleanly (as of 2026-05):
- End-user families who value the development's facility load and intend to occupy for 5+ years — the strengths and risks blocks above outline the day-to-day liveability case.
- Yield investors with HDB+1 portfolios who want OCR/RCR diversification — verify the gross-yield maths via our rental-yield calculator before committing.
- HDB upgraders graduating from a 5-room flat, who need to confirm TDSR headroom and ABSD-remission eligibility — the affordability calculator models the full cash + CPF stack.
This project is less suitable for foreign buyers facing the 60% ABSD ceiling unless under qualifying tax treaty, and for short-hold flippers given Singapore's seller's stamp duty cliff in the first three years.
Verdict (as of 2026-05): The Tampines Trilliant is a credible buy for the post-privatisation EC archetype and a defensible hold for the patient investor — but the thesis depends on you pricing the lease year 15 honestly and stress-testing absorption against the Tampines competitive set.
- Buy if: You want Tampines Regional Centre access with the structural demand expansion that full privatisation in 2025 just delivered, and you are comfortable holding through CRL completion to capture the tri-line MRT re-rating.
- Hold/observe if: Your entry PSF requires capital appreciation faster than the OCR average, since EC quantum-cap psychology may dampen upside even post-privatisation. The 670-unit absorption profile also means yield compression in soft rental years.
- Skip if: You want fresh-lease optics and deeper amenities — in which case Treasure at Tampines fits the brief; or you are waiting for the Tampines Court redevelopment to launch as a cleaner expression of the same thesis on a fresher lease.
Before you commit, model the deal end-to-end: mortgage and amortisation, TDSR headroom, an affordability check against your income profile, and a cash-flow projection for the rental years. For HDB upgraders, also work the decoupling scenarios against future ABSD exposure, and use the ROI calculator to stress-test yield assumptions at 85% occupancy.
Bottom line (as of 2026-05): The Tampines Trilliant is the cleanest expression of the post-privatisation EC trade — a tri-line-MRT-adjacent 670-unit project that just unlocked full open-market access in 2025, sitting on a 99-year lease from 2011 with roughly 84 years remaining. The thesis is straightforward: Tampines Regional Centre + CRL future + EC quantum-cap headroom against private launch pricing.
- Privatisation status: TOP ~2015, MOP cleared 2020, full privatisation 2025. The unit is now sellable to PRs and foreigners — a structural demand expansion the project did not have for its first decade. Model the timing with the total-cost calculator.
- Tri-line MRT thesis: Tampines MRT already serves the East-West Line (EWL) and Downtown Line (DTL); the Cross Island Line adds a third by 2030. See the commute-time map for door-to-CBD isochrones.
- Retail anchor: Tampines Mall, Century Square and Tampines 1 form a three-mall cluster within 5-8 minutes' walk — denser than most Outside Central Region (OCR) suburbs. The heatmap-layers map shows amenity density across District 18.
- Watch-outs: Year 15 of a 99-year lease means buyers must price the runway tail honestly; EC quantum dynamics still anchor resale psychology even post-privatisation; and 670 units competing with Treasure at Tampines (~2,200 units) means absorption matters. Run the lease-decay calculator before signing.
- Best for: Owner-occupiers who want Tampines Regional Centre access with a softer entry PSF than CCR stock, and investors with a 5-8 year hold willing to ride the CRL completion curve.
