Sai Ho Building
Overview & Key Facts
Sai Ho Building is an 8-unit small residential block on Upper Serangoon Road in District 19 (OCR), situated in the Serangoon–Kovan residential corridor — a mature, established private housing area that straddles the North-East Line (Serangoon and Kovan MRT stations) and benefits from the density of the Serangoon Gardens, Kovan, and Hougang residential precincts. The development is definitively in the OCR mid-market segment: the ShiokNest score of 24/100 reflects the OCR classification and the absence of facilities, not a poor-quality address.
The rental evidence — 11 transactions averaging S$3,291 and a median of S$3,300 — positions Sai Ho Building in the D19 OCR private rental tier: affordable private apartment accommodation in an area characterised by HDB upgraders, young families, and the Serangoon Gardens expat community. Serangoon MRT (NE + CC dual-line interchange) at 830 metres and Kovan MRT (North-East Line) at 930 metres provide North-East Line access in a 10–12 minute walk.
The school catchment is a genuine strength for the D19 Serangoon corridor: Cedar Girls’ Secondary at 310 metres, Cedar Primary at 350 metres, Zhonghua Secondary at 420 metres, and Zhonghua Primary at 480 metres form a density of top schools that makes Upper Serangoon Road a well-recognised school-ballot address for families targeting Cedar Primary and the associated secondary school pipeline.
Location & Connectivity
Upper Serangoon Road is one of Singapore’s most densely populated private residential corridors in the OCR, connecting the Serangoon New Town commercial hub (Nex megamall, Serangoon MRT interchange) to the Kovan town centre and the Hougang residential estates northward. The immediate surroundings of Sai Ho Building are a mix of private apartments, HDB mid-rise blocks, conserved shophouses along the Serangoon Road corridor, and the Cedar and Zhonghua school cluster.
Serangoon MRT (North-East Line + Circle Line dual-line interchange) at 830 metres is a significant connectivity asset — the NEL reaches Little India, Dhoby Ghaut, Chinatown, and Harbourfront southward, while the Circle Line connects Paya Lebar, Bartley, Marymount, and Bishan. Kovan MRT (North-East Line) at 930 metres is the northward NEL access point. By car, the address is well positioned for Pan Island Expressway access northward and the central expressway westward.
The Serangoon Gardens estate — the colonial-era landed bungalow enclave immediately north — is a defining lifestyle anchor for the Upper Serangoon area. Chomp Chomp Food Centre (within Serangoon Gardens) is a Singapore institution-level hawker venue. NEX megamall at Serangoon MRT provides full retail, supermarket, cinema, and F&B infrastructure within a 15-minute walk or one MRT stop. The corridor has a strong community character driven by the mix of long-established residents, families targeting the Cedar and Zhonghua school cluster, and the Serangoon Gardens expat community.

Facilities
At 8 units, Sai Ho Building is a small private apartment block without conventional condo facilities. There is no swimming pool, gymnasium, or clubhouse. MCST contributions for an 8-unit block are minimal. The D19 OCR location means the overall product positioning is practical value-focused rather than lifestyle-amenity-rich.
The neighbourhood amenity substitution is strong for an OCR address: Chomp Chomp Food Centre in Serangoon Gardens, NEX megamall’s FairPrice supermarket and cinema, and the cluster of neighbourhood coffee shops and hawker stalls along the Serangoon Road and Upper Serangoon Road corridors provide daily needs within a short walk or bus ride. Serangoon Sports Centre (ActiveSG) provides pool and gym access as a substitute for in-development facilities.
Neighbourhood Comparison
The D19 modern development benchmarks are Chuan Park (99yr, 916 units, $2,596 psf), The Florence Residences (99yr, 1,410 units, $1,745 psf), Riverfront Residences (99yr, 1,451 units, $1,588 psf), and Affinity at Serangoon (99yr, 1,012 units, $1,698 psf). These large-scale leasehold developments offer active resale markets, modern facilities, and defined psf benchmarks.
Sai Ho Building is structurally different: 8 units, likely older vintage, no facilities, and a school-catchment positioning that smaller developments can sometimes sustain despite the scale disadvantage. Buyers choosing between Sai Ho Building and Chuan Park or Florence Residences are making different trade-offs: Sai Ho Building offers a smaller, potentially freehold footprint with Cedar Primary catchment at lower entry cost but zero resale liquidity; Chuan Park offers modern facilities and an active resale market at 99-year leasehold and a higher psf. The D19 school-catchment premium is the primary differentiator.

What Residents Say
“Upper Serangoon for Cedar Primary is the equivalent of Barker Road for SJI in the OCR market. Families with children targeting Cedar Primary specifically seek addresses within the 1km ballot zone. Sai Ho Building is exactly in that zone.”
— D19 school-catchment specialist via PropertyGuru agent network
“Serangoon is genuinely convenient. NEX for shopping, Chomp Chomp for food, the NEL for the city. As an OCR address it doesn’t have the CCR glamour but for practical family living the value proposition is strong.”
— D19 resident via Singapore Expats forum
Strengths & Weaknesses

- ShiokNest score 24/100 reflects OCR classification, not address quality — context required
- Serangoon MRT at 830m is a 10+ minute walk; Kovan MRT at 930m is similar
- Zero resale caveats — no public psf benchmark; requires independent valuation
- No in-development facilities — no pool, gym, or concierge

- OCR pricing limits capital appreciation upside versus CCR alternatives
- Upper Serangoon Road is a busy arterial — road-facing units may have noise exposure
Verdict
Sai Ho Building is a no-frills D19 OCR private rental income play. The Cedar Primary and Zhonghua Primary school catchment at 350–480 metres drives consistent family-tenant demand. The Serangoon MRT dual-line interchange at 830 metres provides practical connectivity. The S$3,300 median rent from 11 transactions confirms a stable, if modest, rental income stream.
The ShiokNest score of 24/100 is harsh for what is essentially an acceptable OCR school-catchment rental investment — it reflects the OCR classification, the micro scale, and the absence of facilities rather than a fundamentally flawed address. For a buyer seeking a D19 OCR school-catchment rental hold at an entry price accessible relative to CCR alternatives, and who accepts the thin resale data and the lack of facilities, Sai Ho Building delivers what it promises: a small, quiet, school-adjacent private block in an established Serangoon residential corridor.
