The two skyscrapers - Hang Lung Properties' Summit and Central Development's Highcliff - have been described by some as 'chopsticks'.

They were approved several years ago when there was no building height restriction in the area.

Their high-rise structures were found to be highly incompatible with the low and medium-rise building character of the area, prompting the need to impose restrictions.

Under the new rules, residential buildings within the Residential (Group B) zone along Stubbs Road and Wong Nai Chung Gap Road will be restricted to 22 storeys and a plot ratio of three times the site area.

Despite the new restrictions, the 27 property owners sought to increase the building density of certain lots to a plot ratio of between 4.5 and five times.

One owner argued that his property was next to the two skyscrapers and that a density relaxation would allow for a larger-scale redevelopment to reduce its incompatibility with the high-rise structures.

Some owners are worried of reduced redevelopment potential of their lots because of the redefined lot boundary under the new outline zoning plan for the district.

A planning board spokesman said the 27 owners' application for a density relaxation was not accepted.

But the demand by two other owners of neighbouring properties to raise potential building density was granted.

The two properties are on No44 and 53 Stubbs Road and they under a different zoning, the Residential (Group C).

In a separate objection, the two owners applied to increase the plot ratio, or building density, to 2.1 times from 0.5 time proposed under the outline zoning plan.

The board spokesman said the relaxation was acceptable because the two lots were located in a transitional area from medium-rise to low-rise developments.
