The projected private flat supply for the next three to four years is 104,000 units, 2,000 more than the previous estimate.

The Housing Bureau said today there were 23,000 unsold units in completed projects at the end of December last year.

There were also 61,000 units under construction, excluding those pre-sold by developers; and 20,000 units from disposed sites where construction may start at any time.

The number of flats under construction in the fourth quarter last year was 1,900, while 5,100 units were completed during the same period.
