finally saw the pricing info at HDB's website:
The apartments at The Pinnacle@Duxton are classified as "S" or Special apartments in view of its historical significance and award-winning design. In Phase 1, there are 352 units of Type S1 apartments with floor areas ranging from 93 to 97 sqm, and 176 units of Type S2 apartments with floor areas ranging from 105 to 108 sqm. For application of HDB policies, S1 and S2 apartments will be treated as 4-room and 5-room flats respectively.
5The indicative prices of the apartments at The Pinnacle@Duxton offered in the Phase 1 BTO launch start from $289,200 for a S1 apartment and $345,100 for a S2 apartment.
Think the prices are a bit low actually.... in comparison to the new batches of flats from Toa Payoh, Redhill and Tiong Bahru. I remembered some of these were priced around $400k for 5 room!
