Perfect Ten stands on the former City Towers site at 321 to 323 Bukit Timah Road — a collective sale that is the only realistic way a freehold plot of 104,531 sqft comes to market in this part of District 10. The development is two blocks of 24 storeys holding 230 apartments, designed by DP Architects for Japura Development Pte Ltd, the Singapore residential arm of Hong Kong-listed CK Asset Holdings.

The site planning is deliberate about its position. The blocks sit roughly 100 metres back from Bukit Timah Road, which buffers the apartments from the traffic on one of Singapore's busiest arterial roads and gives the development a quieter aspect than its address suggests. The outlook takes in the greenery of the surrounding landed estates and toward the Bukit Timah nature reserve, and the rooftop level is designed to give 360-degree views rather than a single favoured elevation.

The water programme is unusually developed for the category. The landscape deck carries a 50m infinity pool with an estimated surface area of about 600 sqm, a kids' pool of roughly 47 sqm, an aqua gym of about 43 sqm, and separate ion, spa and mineral pools of between 6 and 7 sqm each. At basement level there is a piazza, a cascading water feature, a boulevard driveway, green walls, landscape berms and a grand drop-off. Estimated maintenance fees are $522 for a two-bedroom and $610 for a three-bedroom before GST.

But the reason most buyers look here is the school belt. Anglo-Chinese School (Primary) is about 333m away and ACS (Barker Road) roughly 385m — a four-minute walk to both — with Singapore Chinese Girls' School about 623m, SCGS Primary around 695m and St Joseph's Institution roughly 825m. Newton MRT, an interchange between the North-South and Downtown lines, is about 800m, with Stevens on the Thomson-East Coast Line roughly 818m. Balmoral Plaza is about 317m and Cold Storage around 650m. The development reached TOP in the fourth quarter of 2025 and all 230 units have sold.
