Swire Properties' application to the Town Planning Board to relax the plot ratio for the Rocky Bank luxury development on Deep Water Bay Road is likely to receive the green light from the Planning Department. The Company has asked to raise the plot ratio for the 28,200-sq ft site from 0.5 to 0.532 times to accommodate plans to redevelop the site to two three-storey luxury houses, with a buildable area of 15,000 sq ft.
