THE higher-end of the public housing market is showing its first signs of cooling, with the Housing Board's latest condo-style flats receiving a lacklustre response. With only one day left to the closing of applications, Natura Loft at Bishan has drawn about 600 applications for 480 flats, its developer told The Straits Times yesterday. This is in stark contrast to the previous three projects built under HDB's design, build and sell scheme (DBSS), which attracted overwhelming demand. The first project, Premiere @ Tampines, was a hit, with 6,000 applications for 616 homes; City View @ Boon Keng had 3,500 buyers vying for 714 flats while the third project, Park Central at Ang Mo Kio, drew 2,300 bids for 578 units
