Domain 21
Overview & Key Facts
Domain 21 is a 141-unit leasehold condominium at 21 Delta Road in District 3, completed in 2007 and developed by Kheng Leong Co. Pte Ltd (through its development vehicle Valley Development Pte Ltd) — one of Singapore’s long-established private property companies with roots in the local market stretching back decades. The development rises across two towers — Tower 21 and Tower 23 — to 22 storeys, offering a boutique mid-rise address on the fringe of the Tiong Bahru conservation district.
District 3 occupies the city-fringe RCR (Rest of Central Region) corridor between the CBD and the Alexandra–Queenstown residential belt. Delta Road sits near the point where Tiong Bahru’s art-deco prewar shophouses give way to the modern HDB and private residential fabric of the Redhill–Alexandra precinct. For buyers navigating RCR pricing, this geography delivers genuine urban proximity — the CBD is under 4 km by road, Orchard Road under 3.5 km — without the premium ticket of Districts 9 or 10.
The development’s financials tell a coherent value story. With 32 recorded resale transactions averaging $1,828,150 ($1,750 PSF) and 177 rental transactions averaging $5,085 per month, the implied gross yield sits at approximately 3.3% — meaningfully above the 2.5–2.8% that freehold or longer-lease RCR peers typically generate. Critically, the 99-year lease from 2004 leaves approximately 77 years remaining as of 2026 — still comfortable for financing and CPF usage, though buyers should note that the 75-year CPF threshold will be crossed within roughly two years, after which CPF Ordinary Account usage for resale purchases becomes subject to increasing restrictions.
For investors, Domain 21 occupies a well-defined niche: a mid-size RCR development in a walkable Tiong Bahru-adjacent address, with a yield profile that outperforms freehold comparables in the district, at a PSF level ($1,750) that still trails newer D3 launches by a material margin. The two-tower configuration — Tower 21 offering canal views, Tower 23 facing the main road — creates meaningful within-development value differentiation that buyers should understand before committing.
Location & Connectivity
Domain 21 sits on Delta Road in the RCR city-fringe stretch of District 3, positioned between two of Singapore’s most characterful urban precincts: the Tiong Bahru conservation belt to the north and the Alexandra–Queenstown HDB estate to the south. The address is urban in character — Delta Road is a low-traffic residential street, but Alexandra Road and Lower Delta Road are both within a few minutes’ walk, providing comprehensive bus connectivity in multiple directions.
MRT access is a genuine strength. Tiong Bahru MRT (EW17) on the East West Line is approximately 680 metres from the development — a comfortable 8–10 minute walk that most residents manage door-to-door. From Tiong Bahru station, the CBD (Raffles Place, City Hall) is two to three stops east; Jurong East and the western employment corridor are accessible heading west. Havelock MRT (TE16) on the Thomson-East Coast Line is approximately 1.5 km away, adding a second MRT line for cross-island connectivity including direct access to the Marina Bay and Woodlands corridors without transfer. This dual-line access — EWL via Tiong Bahru, TEL via Havelock — represents a meaningful connectivity advantage over single-line D3 developments.
The Alexandra Road precinct delivers robust day-to-day retail and lifestyle infrastructure. IKEA Alexandra and Queensway Shopping Centre are within 1–1.5 km. Tiong Bahru Plaza, with an NTUC FairPrice, FairPrice Finest, and a dense cluster of F&B and retail tenants, is approximately 600–700 metres away. The legendary Tiong Bahru Market & Food Centre — widely regarded as one of Singapore’s finest hawker centres and a destination in its own right — is less than 1 km from the development.
The Tiong Bahru neighbourhood context is a compelling location story in its own right. The conservation belt of prewar art-deco shophouses on Yong Siak Street, Eng Hoon Street, and Tiong Bahru Road has matured into one of Singapore’s most-cited lifestyle destinations — independent cafés, bookshops, wine bars, independent grocers, and boutique retailers occupy the ground floors of what are among Singapore’s most architecturally protected streetscapes. Residents of Domain 21 are a 10–15 minute walk from this precinct, and the Tiong Bahru identity adds a liveability and aspirational quality to the address that raw proximity statistics do not fully capture.

Facilities
Domain 21 offers a well-rounded facilities package appropriate to a 141-unit boutique mid-rise development from 2007. The core amenities include a swimming pool and wading pool, gymnasium, clubhouse, outdoor pavilion, BBQ pits, and ample basement car parking. Secure lift access serves both towers, and 24-hour security with guarded access is maintained throughout the estate.
The two-tower layout — Tower 21 (three units per floor, canal-facing) and Tower 23 (four units per floor, main road-facing) — gives the development a campus-like quality that allows shared amenity space between a relatively small population of residents. With 141 units across two towers, the facilities are never under capacity pressure: the pool, gym, and clubhouse are available on demand rather than subject to the crowding that larger mass-market developments routinely experience. Residents consistently note this as a practical advantage of the boutique scale.

The direct connection to the Alexandra Park Connector via a side gate in the estate perimeter extends the development’s effective recreational footprint beyond its own grounds. The connector links to Tiong Bahru Park, Henderson Park, and ultimately the Southern Ridges trail — providing residents with access to kilometres of green corridor without touching a road. This is an amenity that upgrades the development’s lifestyle offering meaningfully beyond what its modest private grounds alone would suggest.
Maintenance standards have been consistently well-regarded in resident feedback. For a development approaching its 20th year, Domain 21’s common areas and facilities remain in sound condition — a reflection of a competent MCST and the building’s original Kheng Leong construction quality. Maintenance fees are in line with boutique D3 condos of similar vintage and facility profile.
Unit Sizes & Layout
Domain 21’s 141 units span a practical mix across four categories: 1-bedroom (560 sqft, 18 units), 1-bedroom + Study (775 sqft, 1 unit), 2-bedroom (883–1,098 sqft, 80 units across two size bands), and 3-bedroom (1,281 sqft, 36 units). The two-bedroom tier is the dominant category at 57% of all units, reflecting the development’s positioning toward investor-oriented and small-family buyers rather than the large-family market. The 3-bedroom at 1,281 sqft is spacious by current RCR standards and comfortably accommodates a couple with one or two children without the layout compromises that post-2015 RCR launches routinely impose.
The average transacted size implied by the financials — roughly 1,044 sqft at $1,828,150 average price and $1,750 PSF — aligns with the upper two-bedroom and entry three-bedroom range, confirming that the larger units account for a disproportionate share of recorded transactions. This is typical of boutique mid-size developments where the 2BR+ tier drives secondary market activity while the 1BR tier provides high-yield investment entries.
Layout quality reflects the 2007 development vintage, which preceded the industry-wide compression of internal dimensions that characterised Singapore’s new launch market from approximately 2015 onwards. Two-bedroom units in the 883–1,098 sqft range offer genuine living-room separation from the sleeping zone — a functional standard that many post-2018 RCR launches at equivalent or higher PSF no longer deliver. The 1,281 sqft three-bedroom floor plan provides three properly proportioned bedrooms with adequate combined living and dining space for owner-occupier comfort.
Finishings across all unit types are consistent with mid-market RCR standards for a 2007 Kheng Leong development — functional marble and tile flooring, standard bathroom fittings, and kitchen layouts that accommodate a working domestic kitchen without imported appliance upgrades. Units transacting in the current resale market at $1,750 PSF typically reflect some degree of renovation since original TOP condition. Buyers should budget $30,000–$60,000 for a mid-range renovation depending on unit size and condition, and inspect carefully for any deferred maintenance in the 18-year-old building fabric.

Neighbourhood Comparison
Meraprime is Domain 21’s closest and most direct competitor: a D3 leasehold development, also boutique scale, located approximately 140 metres from Tiong Bahru MRT — measurably closer to the station than Domain 21’s 680-metre walk. Developed by MCL Land, Meraprime trades at a slight PSF premium to Domain 21 in recent years, which reflects the MRT proximity advantage and MCL Land’s well-regarded construction quality. For buyers where MRT walkability is the primary location criterion, Meraprime is the superior option; Domain 21 partially compensates with its canal views (Tower 21), the Alexandra Park Connector gate, and the Tiong Bahru lifestyle immersion of the Delta Road address.
Principal Garden at Prince Charles Crescent (D3, UOL Group, 663 units, completed 2018) represents the segment above Domain 21 in scale, vintage, and developer pedigree. Transactions have averaged $1,900–$2,100 PSF in recent years — a $150–$350 PSF premium over Domain 21. The premium reflects UOL Group’s flagship-quality finishings, a substantially larger and more comprehensive facilities deck (50m lap pool, multiple tennis courts, full gym, clubhouse), and a longer effective lease (99yr from 2013, some 15+ years more remaining than Domain 21). For buyers with additional budget, Principal Garden offers a significantly upgraded product; Domain 21’s counter-case is the 3.3% yield premium versus Principal Garden’s 2.6–2.9% and the boutique character that large-scale condos cannot replicate.
In the broader D3 comparison set, Alexis (Alexandra Road, 293 units, freehold, completed 2012) offers perpetual tenure at approximately $1,700–$1,800 PSF — comparable pricing to Domain 21 but with the fundamental advantage of freehold title. For buyers who are CPF-usage sensitive or planning a long hold, Alexis’ freehold status eliminates the lease-decay risk entirely and commands consideration at similar price points. Domain 21 competes with Alexis on the Tiong Bahru address quality and the park connector access, but buyers who can acquire Alexis at equivalent or near-equivalent PSF should think carefully before choosing a 77-year leasehold over a freehold title.
On the rental demand side, Domain 21’s 177 rental transactions and $5,085 average monthly rent position it strongly within the D3 cluster. The Tiong Bahru MRT at 680 metres — not walking-distance-elite but genuinely walkable — supports professional tenant demand, and the neighbourhood’s reputation as one of Singapore’s most liveable urban precincts commands a rental premium from quality tenants who actively seek the address. For investors benchmarking yield across D3, Domain 21’s 3.3% is at the high end of the RCR yield distribution for this PSF level, which is the development’s clearest investment merit.
| Development | Tenure | TOP | Units | ~Avg PSF |
|---|---|---|---|---|
| DOMAIN 21 | 99 yrs lease commencing from 2004 | 2007 | 141 | $2,032 |
| ZYON GRAND | 99 yrs lease commencing from 2024 | 2025 | 1,079 | $3,052 |
| AVENUE SOUTH RESIDENCE | 99 yrs lease commencing from 2018 | 2021 | 1,074 | $2,261 |
| STIRLING RESIDENCES | 99 yrs lease commencing from 2017 | 2021 | 1,259 | $2,275 |
| PENRITH | 99 yrs lease commencing from 2024 | 2025 | 462 | $2,796 |
| ONE PEARL BANK | 99 yrs lease commencing from 2019 | 2021 | 774 | $2,569 |
Lease Decay Analysis
The 99-year lease runs from 2004, meaning approximately 22 years have already been consumed. Roughly 77 years remain — still comfortably within the range where most banks will offer full financing without restrictions.
| Year | Lease remaining | Implication |
|---|---|---|
| 2026 (now) | ~77 years | Full bank financing available |
| 2034 | ~69 years | CPF usage still unrestricted for most buyers |
| 2043 | ~59 years | Approaching 60-year threshold — CPF limits begin for some |
| 2063 | ~39 years | Significant financing restrictions for next buyer |
| 2103 | Expiry | Lease reverts to state |
For a buyer purchasing today with a 10-year horizon (exit around 2036), the lease situation is essentially a non-issue — you’d be selling a property with ~67 years remaining, which is still very bankable. The risk profile changes for longer holds.

What Residents Say
“Beautiful apartment building with good views of the city. Good in-house facilities like a gym and a swimming pool. Within walking distance from the MRT and a number of shops.”
— Resident review via SingaporeExpats.com
“Quiet street but close to everything — Tiong Bahru MRT is an easy walk, the food centre is great, and the park connector means you can run all the way to the Southern Ridges without crossing a road.”
— Owner review via 99.co
“Canal view from Tower 21 is genuinely lovely in the evenings. Small development means the pool is always quiet, and the management keeps the place well. The Tiong Bahru lifestyle is the real selling point for us.”
— Resident review via PropertyGuru
“Solid investment unit — rented out quickly and the yield has been good. The lease is something to watch but for now it is still very bankable. Tiong Bahru rental demand is strong.”
— Investor review via EdgeProp
The resident profile at Domain 21 reflects the dual character of the development: a mix of owner-occupiers drawn to the Tiong Bahru lifestyle address and CBD proximity, and investors attracted by the above-market yield and strong rental demand from professionals working in the CBD, HarbourFront, and the Alexandra business corridor. Expatriate tenants — particularly those from European backgrounds who appreciate the Tiong Bahru shophouse aesthetic — account for a meaningful share of the rental population and drive the strong $5,085 average monthly rent. Feedback across platforms is consistently positive on the Tiong Bahru neighbourhood, the park connector access, and the boutique scale; the lease duration is the recurring investor-level concern, and prospective buyers will hear this flagged in virtually every agent or resident conversation about the development.
Strengths & Weaknesses
- Tiong Bahru MRT (EW17) at 0.68 km — comfortable 8–10 min walk to East West Line
- Dual MRT line access — EWL via Tiong Bahru, TEL via Havelock for cross-island connectivity
- 3.3% gross yield — outperforms most freehold and longer-lease RCR comparables at similar PSF
- Alexandra Park Connector direct gate access — runs to Southern Ridges, Tiong Bahru Park without crossing a road
- Tower 21 canal views — three units per floor, quieter setting away from main road
- Tiong Bahru lifestyle precinct — conservation shophouses, hawker centre, boutique cafes within 15 min walk
- Boutique scale (141 units) — pool and gym are rarely congested
- $1,750 PSF RCR D3 value entry — below newer D3 launch pricing by $300–$500 PSF
- Strong rental demand from CBD and HarbourFront professionals, expatriate tenants
- Tiong Bahru Plaza and NTUC FairPrice within 700m for daily shopping
- 77-year lease remaining — CPF 75-year threshold will be crossed in ~2 years (2028), reducing buyer CPF optionality
- Lease decay will progressively constrain financing and resale liquidity for long holds beyond 10 years
- Kheng Leong / Valley Development — smaller developer profile versus MCL Land, UOL, or CDL comparables
- 2007 construction vintage — kitchens and bathrooms may need renovation budget of $30,000–$60,000
- No freehold option in this sub-market at equivalent PSF — Alexis (FH) is a meaningful alternative to evaluate
- Meraprime (140m from Tiong Bahru MRT) has stronger MRT proximity despite similar D3 positioning
- Tower 23 units face main road with more urban exposure and less premium outlook versus Tower 21
- Facilities modest by current standards — no lap pool or tennis court; suitable for boutique lifestyle, not resort-style living
Verdict
Domain 21’s investment case is built on three compounding strengths: a genuinely walkable MRT position (Tiong Bahru EWL, 0.68 km), a Tiong Bahru lifestyle address that commands neighbourhood premiums above what District 3 broadly delivers, and a gross yield of approximately 3.3% that outperforms most freehold and longer-lease RCR comparables at similar PSF. For investors running a yield-plus-growth model in RCR, this combination is hard to replicate in the immediate sub-market.
The 77-year lease remaining is the development’s most significant structural constraint, and it operates on two time horizons. In the near term (2–3 years), the approaching 75-year CPF threshold will incrementally reduce the eligible CPF usage for future resale buyers, which could place moderate downward pressure on resale liquidity and pricing relative to longer-lease peers. In the medium term (5–10 years), financing availability begins to narrow as lenders apply haircuts to leasehold properties with sub-70 years remaining. Neither constraint is acute today, but buyers who are not intending to hold for the full remaining lease should model a 5–8 year exit horizon as the optimal resale window before these dynamics become pricing-relevant.
On the capital appreciation side, Domain 21’s trajectory reflects steady but not spectacular growth consistent with D3 city-fringe RCR dynamics. The Tiong Bahru precinct’s sustained popularity as a lifestyle destination — and its relative supply constraint, given the conservation-area protections on surrounding shophouse land — provides a structural demand floor that insulates the address from the more volatile pricing that can characterise larger RCR mass-market precincts like Toa Payoh or Bishan. Nearby Principal Garden (D3, UOL, larger at ~663 units) and Meraprime (D3, 140m from Tiong Bahru MRT) serve as direct benchmarks: Domain 21’s advantage is boutique scale and the Alexandra Park Connector access; its disadvantage is the ageing lease.
Domain 21 is a well-positioned RCR value play for investors who understand the lease clock: buy it for the Tiong Bahru address and 3.3% yield today, hold for 5–7 years with full CPF advantage intact, and exit before the 75-year CPF threshold reshapes the buyer pool.
Owner-occupiers seeking a liveable, walkable D3 address in a boutique low-density setting will find Domain 21 genuinely attractive at current pricing. The combination of canal views (Tower 21), park connector access, Tiong Bahru lifestyle infrastructure, and Tiong Bahru MRT within a 10-minute walk represents a liveability package that many newer D3 launches at higher PSF do not materially improve upon. The caveat is that any buyer planning a long hold of 15+ years should factor lease decay into their total return modelling from the outset.
