Topaz Mansions
Overview & Key Facts
Topaz Mansions is a rare freehold boutique development tucked along the quiet, tree-lined Topaz Road in District 12's Potong Pasir enclave. Completed in 1993, this intimate 14-unit block occupies a private residential pocket just off Upper Serangoon Road, offering a level of seclusion that larger developments simply cannot replicate. With a small management corporation and a tight-knit community of owner-occupiers, the development has matured into a well-maintained, unhurried address that appeals strongly to those who prize privacy over prestige.
The development comprises exclusively spacious 3-bedroom apartments spanning roughly 1,055 to 1,238 sq ft — a generous footprint by today's standards — reflecting the era's preference for comfortable family-sized layouts over the shrunken configurations common in modern launches. At a 12-month average of S$1,244 psf on freehold land, Topaz Mansions represents one of the more value-laden freehold opportunities in the RCR belt, underpinned by genuine liveability rather than marketing gloss.
Transaction activity is naturally thin given the building's size — only 14 units means turnover is infrequent — but recent sales at S$1.41M–S$1.58M and a recorded PSF appreciation from S$1,228 to S$1,277 over the tracked window confirm steady, if quiet, capital preservation. With 10 rental transactions logged and a gross yield of 2.83%, the building also draws long-term investors who value freehold tenure and stable tenancy over rapid churn.
Location & Connectivity
Topaz Road branches off Upper Serangoon Road in a predominantly residential precinct sandwiched between the Potong Pasir HDB estate and the private landed and condo clusters of Bidadari. The street itself is short and lightly trafficked, lined with mature trees that give it a calm, almost kampung-adjacent character despite its central Singapore address. Residents step onto Upper Serangoon Road for buses and neighbourhood retail within a two-minute walk, yet return home to a road that sees almost no through-traffic.
Potong Pasir MRT (NE10) on the North-East Line is 460 metres away — a comfortable seven-to-eight minute stroll that makes the development genuinely car-optional for daily commuters. The NE Line connects directly to Dhoby Ghaut (one-stop interchange to the CC and NS lines), Serangoon (interchange to the CC and Cross-Island lines), and Orchard in under 15 minutes. A second MRT option — Geylang Bahru (DT24) on the Downtown Line — sits 950 metres east, offering an alternative routing through the city centre and Buona Vista without a transfer.
Day-to-day amenities are plentiful within walking range. The Poiz Centre beside Potong Pasir MRT houses an NTUC FairPrice, pharmacy, food court, and essential services. Broadway Food Centre and the Potong Pasir HDB hawker stalls provide affordable, authentic cooked food within 10 minutes on foot. NEX mall at Serangoon and City Square Mall at Farrer Park are each one MRT stop away for bigger retail runs. The Bidadari Park development nearby has introduced fresh green spaces, a heritage trail, and community gardens that have subtly elevated the neighbourhood's lifestyle quotient in recent years.

Facilities
As befits its boutique scale of 14 units, Topaz Mansions offers a focused set of communal amenities rather than the sprawling facility decks associated with larger condominiums. Residents share access to a swimming pool, a covered car park, and landscaped garden grounds that benefit from the relatively generous plot-to-unit ratio. The absence of elaborate gym wings or multiple function rooms is not a shortcoming — it keeps maintenance fees lean and communal areas genuinely usable rather than perpetually crowded. Owners regularly cite the low-density environment as the development's most prized amenity in itself: there is always a lane free in the pool and never a queue for the lift.
"What I value most is the peace and quiet. The pool is almost always empty, the grounds are well-kept, and I feel like I live in a private house rather than a condo. You can't put a price on that in Singapore." — Long-term owner-occupier, Topaz Mansions
Pricing & Market Position
Based on 3 recorded transactions, sale prices range from $1,410,000 to $1,498,000, averaging $1,464,333 (~$1,244 psf).
Rents range from $2,200 to $4,240 per month across 10 rental transactions. Current rental yield sits at approximately 2.8%.
Price Appreciation
From 2025 to 2026, the average PSF has appreciated by 3.9% (from $1,228 to $1,277 psf).
Neighbourhood Comparison
Against its D12 RCR neighbours, Topaz Mansions stands apart on two axes: tenure and price. The Orie commands S$2,730 psf on a 99-year lease; Gem Residences trades at S$1,833 psf (99-year); Verticus — the only comparable freehold peer — sits at S$2,122 psf for a newer build. Topaz Mansions at S$1,244 psf freehold implies a discount of 41% to Verticus and over 50% to The Orie. The trade-off is liquidity, vintage, and facilities depth. Buyers who require a new-build finish, a full gym-pool-BBQ deck, and developer warranty should look to those projects. Buyers who prioritise freehold land ownership, genuine bedroom sizes, and a tested community in a walkable neighbourhood will find Topaz Mansions difficult to beat on a value-per-square-foot basis within the same district.
Eight Riversuites (S$1,644 psf, 99-year) and Trevista (S$1,698 psf, 99-year) both offer more facilities and higher unit counts, but both sit on depreciating leases. Over a 20–30 year hold, the freehold premium embedded in Topaz Mansions becomes increasingly meaningful, particularly as neighbouring Bidadari continues to mature and uplift the broader Potong Pasir–Woodleigh corridor.

What Residents Say
"We've been here nine years and have no plans to move. The neighbours are stable, the management is responsive, and Potong Pasir MRT is a five-minute stroll. It's genuinely rare to find freehold this close to an interchange at this price."
— Owner-occupier family, 3-bedroom unit
"I rent here for the space. My previous condo at twice the price had a smaller living room. The building is quiet, the pool is never crowded, and getting to town on the NE Line takes about twelve minutes. Very happy with the value."
— Long-term tenant, professional couple
"As an investor, what attracted me is the freehold tenure and the Bendemeer school proximity. Families looking for a 3-bedroom within the primary school registration distance are willing to pay fair rent, and I've had consistent occupancy since I purchased."
— Investor, owns single unit for rental
Strengths & Weaknesses

- Stable rental demand with 10 recorded transactions and 2.83% gross yield
- Bidadari development nearby driving neighbourhood uplift and greenery improvements
- Quiet, low-traffic residential lane while remaining minutes from Upper Serangoon Road amenities

- Surface or older car park infrastructure typical of early 1990s boutique developments
Verdict
Topaz Mansions occupies a narrow but well-defined niche: a freehold boutique in a walkable, MRT-connected part of central Singapore, priced at a meaningful discount to newer RCR developments that offer smaller units on 99-year leases. It is not a development that courts first-time buyers seeking lifestyle amenities or investors chasing rental velocity — it is a quiet, steady address for buyers who understand that freehold land in District 12, within 500 metres of an MRT, does not depreciate to zero.
The ShiokNest score of 54/100 reflects the development's trade-offs honestly: the investment score of 44/100 acknowledges thin liquidity (14 units means infrequent comparable sales), and the facilities score reflects a minimal communal deck. But the walkability score of 78/100 is the genuine anchor — it means residents live comfortably without a car, an increasingly rare attribute at this price quantum. The 2.83% gross yield, while not exceptional, is stable and supported by consistent rental demand from Bendemeer school proximity and easy access to the CBD via the NE Line.
For the right buyer — a small family wanting space and tenure security, a savvy investor holding for long-term appreciation, or a downsizer seeking a quiet, low-maintenance home near the city — Topaz Mansions deserves serious consideration. Buy it for the land, the freehold title, and the address. Do not buy it expecting resort facilities or rapid capital gains from a thin-volume market.
